SKU: 1 Category:


  • Uncurly is the only at-home Brazilian keratin that equals or exceeds any salon’s results
  • A 4 oz bottle (but we like to fill it to 4.5 oz — love ya!) contains 2-5 keratin treatments per typical client, depending on hair length, volume, porosity, and treatment iteration
  • Instructions included


Uncurly’s salon-quality formulas deliver a transformative keratin “topcoat” delivering every advantage of a top-level salon’s high-performance Brazilian keratin treatment:
  • Frizz-free, pouf-free hair — even in high humidity or heavy perspiration
  • Lasts 3-6 months — longer with successive treatments
  • Versatile styling — go straight and sleek, or loosened curls
  • Drying + styling time cut between one half and one tenth — fewer tangles, too
  • Restores hair damaged by bleach, heat, and relaxers to like-new condition
  • Natural-friendly — great for transitioning from relaxers
  • Strengthens against breakage for dramatically longer growth
  • Costs $15-$25 per typical treatment, depending on length and volume
  • Cruelty-free — no animal testing ever


Same Ingredients, Different Strengths

  • Uncurly Classic and Uncurly Plus contain exactly the same ingredients, but Uncurly Plus is a stronger concentration.
  • “Stronger” does not mean harsh or damaging. Both Uncurly Classic and Uncurly Plus are incapable of damaging your hair because they don’t break the hair’s molecular bonds the way relaxers, texturizers, and Japanese thermal reconditioning do.
  • Instead, Uncurly works by means of a protective keratin “topcoat” that smooths curl, eliminates frizz, and restores abused hair to like-new condition.
  • Both Uncurly Classic and Uncurly Plus are 100% safe for weak, damaged hair, and may be used on top of previous keratin treatments, relaxers, or hair color/bleach.

When to Choose Uncurly Classic:

  • Now in its 6th year of fabulous, high-performance results, Uncurly Classic is as effective as any salon’s Brazilian keratin treatment – indeed, more effective than many salon keratins, according to our clients.
  • Even if you had mediocre results from a salon keratin treatment, Uncurly Classic may still be right for you. When in doubt, do not hesitate to contact us for help determining the right formula for your goals. You might also consider ordering a sample.


  • You had great results with Uncurly Classic or other professional keratin treatments;  OR
  • You have Type 2 or Type 3 curls and want a frizz-free, smoothed out look, AND WHEN YOU — USE HEAT to style you still want more bend (ex: the ends turned under or flipped up) or some curl or wave, as opposed to a straighter style;  OR
  • You have low-volume or fine hair and are concerned about it looking too flat or thin.

When to Choose Uncurly Plus:

  • Uncurly Plus is formulated for hair that needs a treatment with extra “oomph” due to intense or resistant curl, extreme humidity, or preference for straighter hair. Types 3 and 4 hair will still retain some curl, particularly when air-dried, but when heat is used, they will smooth out more rapidly and easily than hair treated with Uncurly Classic. Frizz control will also be stronger and the treatment will last longer than Uncurly Classic.
  • Uncurly Plus has been extraordinarily well received by its intended clientele.
  • As Uncurly Plus wears off, the hair will pass through the stage it would have reached with Uncurly Classic.


  • You’ve used Uncurly Classic before and think your hair would perform even better with a more powerful treatment; OR
  • Your hair is difficult to straighten (i.e., Type 4a/b/c and some Type 3a/b/c hair) or has an extreme frizz problem;  AND
  • WHEN YOU — USE HEAT to style (blow dry, flat iron), you prefer a very straight look with less curl, bend, wave. You will still retain some loosened curl when air drying — particularly Type 4 hair — but it will be less than with Uncurly Classic.


If you’d like guidance in deciding which formula to use, try our free online Consultation.  We’d suggest sending in:

  • a picture or two of your hair (or similar), either air-dried or showing your styling problem
  • a picture or description of how you’d like it to look afterward (not essential but may be helpful)
  • info about your local humidity level
  • info about the styling effort you’re willing to make on a regular basis (i.e., air dry, blow dry, flat iron, etc.)

  1. Franki

    Uncurly is like liquid gold to me. It has worked wonders on my afro/asian mix curls for over 4 years now. It’s easy to apply, and leaves my curls defined and frizz free. I’ve shared Uncurly with friends and stylists, and am not surprised by the raving reviews here. I recently cut my hair into a pixie style and tried the Uncurly Plus, which made my hair straighter than anticipated. When I wrote in for help, I received and immediate and kind response and generous guidance. I am a fan for life.

  2. val wolf (verified owner)

    This product straightened my hair and left it SOFT, MANAGEABLE and SHINY better than when I paid several hundred dollars at the Salon! THANK YOU for providing this to the public to use at home!! I will continue to use on my hair !

  3. Allie boo (verified owner)

    I love this keratin treatment. I have used it before in the past and I just placed another order for it recently. I received it very fast and just like before worked wonders on my hair. I have relaxed and colored hair. Which means lots of frizz on my ends but when I use this product it rids my ends of the frizz and makes my hair look/feel so silky and healthy. This product will always be a go to for me . If it’s your first time purchasing and your a little skeptical I say go for it you won’t be disappointed!

  4. Simone L.

    I’d absolutely give this 10 stars if I could. My hair looks and feels fabulous, and it’s not flat which I was scared of. I’ve had a few bad keratin experiences before (in a salon, Keratin Express, I think?, that washed out in a month, and two home products that barely made a dent) so despite the good reviews online I was prepared to be at least somewhat disappointed but WOW. This is absolutely the best keratin treatment I’ve ever had. The staff was friendly and helped me decide which version to buy — I like patronizing good people. Very easy to do and I’ll get at least 3, maybe 4 treatments out of the bottle. Merci beaucoup!

  5. Crystal S.

    I’m glad there’s finally a place to leave a review. Uncurly was a total life changer for me. I had a Brazilian Blowout 4 years ago as a Christmas present and I loved the effects but my husband and I are grad students and it’s not in the budget right now. Someone gave me some Uncurly to try and the results were incredible. I’ve got a ton of stress in my life and it may sound shallow but I feel a lot better when my hair looks good. Naturally, it’s a frizzy, weird curl that I formerly just pulled back every day, but Uncurly makes it gorgeous, even if I air-dry it which I NEVER could have done before. I can blow dry it with or without a brush (two totally different looks, both good) in about 5 minutes and it never frizzes in fog, rain, humidity, etc. Just placed my third order. Excellent product. I never

  6. Tana B.

    All I can say is THANK YOU, THANK YOU! THANK YOU! to whomever came up with this product….my sister and I have spent countless $$$ on trying different hair products only to find that they don\’t work, or if they did, the results are short-lived. I am so glad she told me about this and got it for me….it is truly a life-changing and time-saving product. PLEASE don\’t change anything in the formulation to save money.
    🙂 🙂 🙂

  7. C. L.

    I love this product, it’s a life saver! I perform under hot lights and often in heavy costume, and I cannot begin to tell you the difference it’s made not to have my lifelong frizz problem anymore. Just placed another order and want to say how grateful I am.

  8. Cindy S.

    I moved to the middle of nowhere in Georgia and I absolutely LOVE UNCURLY. It is the closest thing to a professional keratin treatment that I have found. Actually, I take that back, it is BETTER than the salon keratin treatment I used to get in Massachusetts. The instructions and tips were fantastic. I am beyond impressed with the product and the personal customer service. Having Karen contact me to make sure which solution would be the best for my hair was something else. By the way Karen, you were right on that the classic formula was just perfect for my hair. Not only are you an honest, ethical company not trying to oversell all the additional un-needed products, all the questions that someone would need when doing a keratin treatment on their own was covered. Please be around for a long time and thank you so very much for making such a wonderful and affordable product. I look forward to being a loyal customer. Thanks again.

  9. Gemma D.

    My previous keratin had completely worn off and my hair was WILD. When I say wild I meant I’d straighten it and get a teeny bit warm and I’d look like I’d had my fingers in sockets and have to do it all over again! I tied my hair up all week to let it really do its thang and only washed it off just now and OMG I am delighted! It’s softened my curl pattern A LOT, more than any other keratin treatment has and I have paid over £100+ before. I’m fine with the current curl pattern as I never wear my hair curly anyway. I just blow dried it and put a little coconut oil on the ends and I’m good to go, no need for flat ironing! I didn’t even blow dry it properly, I just brushed my hair with the hair dryer blasting it as its bed time so when I section it and do it properly it’ll be even more sleek! I’m absolutely delighted! It feels so soft and healthy! You’re with me forever now!

    Thank you all so much for taking the time to answer lots of questions and being such a lovely group of women who seem to know their product inside out.

    Thanks so much – you’ve save my life and my bank balance 🙂

  10. Theresa R.

    I used Uncurly for the first time in 2015 and have absolutely LOVED the results! I hadn\’t had a decent keratin treatment since salons switched to the “lite” version years ago, which just doesn\’t work on my hair. Put my hair in a pony tail? Take it out and it stays smooth and straight. Get caught in a rain shower? It stays smooth and straight. I just pull it straight while drying with a hair dryer and run out the door. I LOVE LOVE LOVE this product!

  11. Tammi S.

    I purchased your keratin kit last month. I wanted to let you know your customer service was fantastic, shipping was super fast, and I cannot believe the high quality results I got with this keratin treatment! The directions were simple and clear. I feel like a fool for paying up to $600 for keratin treatments in the salons! Thanks again! T S*****

  12. Helena O’R.

    This product WORKS. I was afraid to hope for much and ended up being completely astonished at how well this product performs. I am a very happy customer.

  13. S Carlucci

    I used this last weekend. I love how my hair looks. Works every bit as well as the old Global Keratin (not sold anymore) that was the best I’ve ever used on my brillo-pad hair, until now. You rock!!

  14. Michelle H.

    I just wanted to say how great Uncurly is. I\’ve done two treatments now, and the results are exactly like a salon Brazilian Blowout. The process is easy, and with my shoulder-length hair, it looks like I\’ll get 5 treatments from one bottle of Uncurly. It\’s an amazing value vs. the salon price – at 5 treatments per bottle, I\’m saving over $1500! I also need to wash my hair pretty frequently, and I swim in a chlorinated pool. So my treatments don\’t last quite as long as they would for most people. With Uncurly, I can afford to re-treat when I need to and I always have smooth, frizz-free hair. This is really an excellent product!!!

  15. Jennifer L.

    I wanted to let you know how much I love your product. I\’ve tried everything and this is the only thing that has worked. My life has always revolved around my poufy, frizzy hair and I don\’t have to worry about it anymore. I will be recommending this product to everyone. Thank you so much!

  16. Mary J S

    My hair is healthier than ever and I\’ve now noticed that my uncurly lasts at least to the 6th month before I have to redo the process. No more shedding or breakage!!

    The best hair care decision I have ever made 🙂
    Thanks Uncurly 🙂

  17. D. Oxley

    I am totally amazed at how well this system works! I have very thick mixed curly/wavy/FRIZZY long hair that is a true PIA. I had a Brazilian blowout last year which took nearly 5 hours to accomplish and cost over $500.00.

    I absolutely loved it, but the time and expense were in my opinion prohibitive. Also I had it done in Dallas while on a business trip and I don\’t think anyone in the super eco-friendly Asheville NC where we reside most of the time even does the real version anyway.

    I\’ve been having my hair professionally blown out every week since it wore off and keeping in a bun when we are at our lake house since I cannot handle my bushy fuzzy looking hair.

    I used Uncurly 4 months ago and I still can\’t believe it. I think my results are better than with the professional job! I hardly have to even blow my hair dry and it looks about 1000% healthier/shinier too. To say I am sold is an understatement. 🙂

    As an internet business owner, I spend considerable time on the computer so to take time out of my day to write a review is a big compliment I can assure you.. 😉

    Thanks again. I am actually wearing some makeup at home and dressing nicer because my hair looks so great I want the rest of me to match. lol..

  18. Suzanne H.

    I am totally in love with Uncurly and I am going to give a shout out to you guys on my facebook page! This week has been brutal in Philly, and they are saying it’s going to feel like 107 here tomorrow. Ugh, humidity sucks but IT’S NOT DOING A THING TO MY HAIR!!!

  19. L. Randall

    I’ve been using Uncurly for 4 years. Literally all my life my hair has looked terrible with an uneven wave/ curl, super thick and frizzy, always triangulated at the bottom (if you’ve got this problem you’ll know what I mean). It used to take me an hour to blow dry and flat iron and it still looked bad, especially the back because it took an insane amount of stretching and rolling to get it right and my wrists and patience weren’t enough. Half an hour later it was frizzed again no matter what products I put in it. Uncurly is absolutely amazing. My hair ALWAYS looks great, even after I workout!!! Also, because of the manageability it gives, I’ve been able to switch to a more flattering hairstyle knowing that it won’t frizz. Never thought I’d be able to wear bangs but I am, and they look so much better on me! It takes under 15 minutes to blowdry from dripping wet, then I finesse it with a few quick slides with the flat iron. It looks as good as when my stylist does it and it lasts all day. I may not even need to touch it up the next day. It doesn’t frizz or kink up in the humidity which is saying a lot because I live in Virginia Beach where it’s year-round humid. Thanks for this incredible product!!!

  20. Janine D

    I have had the dreaded unruly curly hair my entire life, and it got worse after I had my daughter. I cannot even walk to my car from my front door on a humid day without the frizz starting. I live on the Jersey Shore, so there\’s always some kind of frizz inducing moisture in the air. I have been paying over $200 for professional keratin treatments for the past few years, plus God knows what I\’ve spent on all of the other hair products I use. My curly haired friend told me that I HAD TO try Uncurly…and so I did. This is the greatest product EVER. I knew it worked as soon as I washed it because my hair felt silky before I even used the dryer. I only had to dry it for 4 minutes (as opposed to my normal 15 of pulling and ironing!)…no product, no flat iron, and my hair is smoother than it has ever been, and straight, but with some body too! It looks like I just stepped out of a salon, but BETTER!There is no breakage, no color fading…just beautiful, silky hair! I am beyond THRILLED and can\’t stop staring at my hair in the mirror and touching it. I\’ve tried just about every product and this is by far the best one I have ever used. I am IN LOVE! I will never go to a salon and spend that kind of money again, when I can do this at home, for a fraction of the price, with better results, AND I still have two treatments left in the bottle! THANK YOU UNCURLY! Your product is like a miracle!!! Ill be telling ALL of my curly haired friends about your product!!!!

  21. Cynthia G.

    Hello, first let me say I love love love your product! It\’s the best ever. My question is can it be used on hair that has been dyed using Henna? My sister uses henna to dye her hair and wanted to know if it would be safe to use on her hair.

    • The Uncurly Girls

      Thanks for the kind words, Cynthia. And yes, Uncurly is safe on henna, as well as on process and semi-permanent color.

  22. E. Duran

    I just wanted to let you know that I am absolutely in love with Uncurly. For the first time ever in my life I am able to blow dry my hair without it looking and feeling like a Brillo pad. My course Irish/Hispanic hair is thinning and all the way down my back. I would normally wet wrap it after every shower and leave it to dry overnight but now all I need is a good 10 minute blow dry and another 10 to flat iron it. I will use this product for the rest of my life. I am thrilled with the results and the first application was a rush job to get it done before the weekend. I wish I would have taken a before picture to show the difference.

  23. Jen Phillips

    My kit arrived in Australia only 6 days after placing my order! I am so thrilled with the product – even better than a Brazilian Blowout.

    It wasn’t hard, quite easy and I even was able to stop, pick up kids, cook dinner, do baths and bed – then finish it. How’s that?

    I will be ordering more stock very soon, I never want to run out!!

  24. Shae

    By far, this is the best product I have used on my hair! This is my third order, and my mom’s a stylist so that says a lot.

  25. P. Carollo

    I have just done my 4th treatment with Uncurly and I am still blown away by this product. My hair is soft and shiny, not the crunchy, frizzy mess that I had for 50 years! I know women who go to the salon for keratin and my hair looks just as good as theirs and it lasts longer!! I don\’t understand why this isn\’t in every drugstore! Thank you! Thank you!

  26. Gina M.

    I am a faithful customer. I\’ve been using Uncurly for about 2 years now. My sister has too. I tptally love this product. Both of our hair has grown dramatically since we began using Uncurly. We have 3b/3c hair that will grow to a certain point (hovering above bra strap) but always breaks off. I believe Uncurly has prevented the breaking and we are retaining length. My hair now touches the top of my behind. LOL! Please continue producing this wonderful product. Because it’s hot and I sweat a lot, I\’ve allowed my new growth to settle in and wear my hair curly.

  27. Kim Racca

    I’ve used this product a few times and I love it! Its so easy to use….works just as good as the expensive salon versions and much more affordable. I would highly recommend it to anyone! I love it!!!

  28. Debra R.

    Just wanted to let you know I love your product. I just placed another order and less than 15 minutes later received an email with the tracking information…..SUPER FAST! I have super thick, super wavy hair and I have never experienced this level of manageability and gorgeousness from my past Brazilian Blowouts, which were in the $300 range. Thanks for the greatest and most affordable keratin straightener.

  29. N. Troske

    I’m so thrilled with this! It really works! It is easy to do, only took me an hour on shoulder length hair. It lasted through coloring (waited 2 weeks) too. I didn’t use a fan but could see why it’s recommended. It’s worth it though for these fabulous results. And I saved a ton of money! Please don’t ever stop offering this system!

  30. Kelly

    I’ve always struggled with my hair’s texture and since moving from the desert of Arizona to the humidity of Texas I was also trying to tame the kink and frizz. My hair is naturally wavy but that wave does crazy things in the humidity and no amount of product can tame my frizz. A friend of mine talked me into trying the Brazilian blow out treatment a year ago and I loved what it did but the cost was prohibitive. I was skeptical before trying Uncurly and planned ahead of time to be disappointed in yet another product, but thought for the price I would give it a try and what if it really did work? I found the entire process to be simple. The smell was the same as when I had it done in the salon and I kept a fan going to dissipate that and once the treatment was over there was no lingering smell such as you would have for days after a perm. I have even been in the rain and my hair did not frizz or fall flat. After I wash my hair now with just a quick blow dry I have achieved what would normally take me a good deal of blow drying with a round brush and then another investment of time with the flat iron. My hair is silky soft and manageable and it stays that way! I can still have my waves and they look so much better as they are smoother and even touchable. The texture of my hair does not feel as coarse and it seems healthier after the treatment and not as dry. To say that I am a satisfied customer would be an understatement. I would wholeheartedly recommend Uncurly to anyone who wants to achieve salon results at a fraction of the cost! Thank you so much for making this product available to everyone!

  31. A. Spiegelman

    LOVE, LOVE, LOVE this product. It has saved me hours of time after I wash my hair. What I really like is that I can let my hair air dry and it will be less frizzy and less puffy with a bit of a curl but if I want it totally straight I can flat iron it just a bit-maybe for six minutes and I’m done. So happy with it. I have really thick, challenging hair so Uncurly has really saved me. Highly recommend it.
    I’ve tried many other Keratins. Some were either too toxic smelling or too weak but this one was easy, a tad bit smelly for a few minutes, and actually works. I also like the personal phone call I got back from the company when I had a question. I like the product and the women who run the company so much – and I don’t even know them, but I feel I do from how well they treat their customers- so I want them to be super successful. Go Uncurly go!

  32. Milly van P.

    During my stay in California (I’m from Netherlands) at the beginning of the year I heard about the Brazilian Keratin Treatment for the first time. I have suffered from very curly/frizzy hair my whole life so it was indeed very interesting to me. I soon discovered that it was very expensive but I found a salon which offered me a reasonable price since my hair was not so long. It was great, I was very happy and immediately I wanted to find a home version that was affordable so that I could also do my daughter’s hair, she too has issues with fizzy hair. Happily I found the Uncurly.com site and decided to order the kit.

    I studied the videos on YouTube on how to actually do the whole procedure, there are many available which made it very easy. The results were great, just as good as the treatment I had at the hairdresser, my daughter was thrilled, No More Frizz, instead beautiful shiny hair! She just washes her hair now and in fact doesn’t blow dry it just enjoys the lovely loose curls. I recently did the second treatment and again it worked just like the first time. I absolutely recommend Uncurly.

  33. Avista B.

    I have NEVER had such a great experience with any product ordered online before! I LOVE IT!!!! Also, the service is impeccable! I recommend Uncurly to all of my friends, even told the girl who does my eyebrows today. She was going to get a Keratin treatment done but after she asked me what I had done with my hair she said that she was going to cancel her appointment and order it. My cousin said the same and so did my sister in law. It’s been just an amazing experience and I had enough left to use on my mom and sister. Thank you so much! Uncurly rocks!

  34. Dani Delgado

    I have naturally messy hair, that will not really curl or straighten on its own, but it’s definitely more on the curly side and there’s a lot of it which is why it naturally poofs. I have been using keratin for about 5 years, mostly at home, but also at salons a few times. In that time, I have tried several types and brands including 2 types of “Global Keratin”, one of which was disappointing and the other fantastic. If you have ever bought or researched Global, you know it’s one of the most expensive in the market, as well as the best. I was pleasantly surprised to find that Uncurly, at less than a quarter of the cost, was as good as the best Global has to offer. The effects lasted about 5 months, and lingered for a couple more months after that. My mom and I both used it, and it still have enough in the bottle for one more application. It was easy to use, although keratin applications are always time-consuming; we were thrilled that it did not call for 3-4 days without washing or styling the hair! Just as with any good keratin, the hair was much healthier and easy to straighten, blow-drying time was reduced to maybe 1/5, flat-ironing was almost unnecessary and used only for minor shaping. This is a great product for an amazing price, and I would highly recommend it to anyone who wants salon results at home!
