I have hair down past my bra clasp, a majority 3B curls with some 2A randomly mixed in and I hate it because my curls are really disorganized. I have straightened it basically every day since I was young, which is about an hour of blow drying followed up with a straightener. Huge pain in the butt time-waster. Due to a sharp increase in workload this semester, I decided I needed a more permanent solution because still I need to look professional at work. I can't look like I've just given up, people! Anyway, I researched keratin treatments (all summer ya'll, all summer) and purchased the 120 ml bottle after reading all the reviews. After doing the treatment, I shampooed with sulfate free shampoo and conditioner and decided to test it out by just letting it air dry (I've always dreamed of doing this). I AM AMAZED! My hair is silky smooth and completely straight! Zero effort required! I literally wanted to cry tears of joy. It's been a couple of weeks and it is still perfect so I have hopes that this will last for the 3 months. For anyone interested, I did not have the patience to follow all of the directions and instead did what was recommended by another reviewer (slightly modified for laziness/impatience): 1. Shampooed (X2) with my dish soap to get all the oil and product out. I didn't feel like ordering a clarifying shampoo, ain't nobody got time for that. No conditioner or products after clarifying. 2. Comb (carefully!) with wide-tooth comb. Let hair air dry. Yeah it looked crazy. 3. A few hours later I applied the treatment all over with a dye brush and combed out the excess. I've been dyeing my hair at home for years but if you don't have practice with that you may want a friend to help that you don't mind seeing you topless. Or wear a towel. Whatever. 4. Blow dry completely. Your hair is gonna feel really bad at this point. Power through. 5. Make sure it is COMPLETELY dry and then flat iron it like you've never flat-ironed before. Go to town, get the roots, make several passes, use a comb, be serious. Torture your hair because it is the LAST time you're going to have to for a very long time (yay!). 6. I think I sat around for like an hour before I finally said forget it, there's no reason to wait, I've heat sealed this stuff and my head has cooled off. Look, I have really nice sheets and I couldn't fathom sleeping with a towel on my head to protect them, ok? Stop judging me. 7. Shampooed and conditioned with sulfate free and Voila! You already read the amazing results. This product is a godsend and I will be ordering it for the rest of my life. One drawback (not the product's fault) that I hadn't thought about it that if I let it air dry, it's pretty flat. I'm not complaining because straight is what I wanted and I can still put any kind of curl in it with a curling iron. However, I have started hitting my roots with a blow dryer for some volume and it works perfectly and takes maybe 5 minutes. Then let the rest air dry. BOOM, this stuff is gold. I just threw out tons and tons of hair products and cleared off my bathroom sink. There's so much room for activities now! Glorious. **UPDATE: I did this treatment in late Aug 2017. It is now the middle of January 2018 and I am about to do another treatment because my roots have grown out quite a bit and are starting to get wavy. It lasted over 4.5 months perfectly. Highly recommend this product.

This keratin treatment left my hair smooth, shiny, and frizz-free. It’s easy to use, works quickly, and lasts for weeks. My hair feels healthier and much easier to style. Highly recommend!

It really does work!! I have tried every type of treatment out there and my hair is so unresponsive. I've tried relaxers, I've tried perms with big curlers to soften the curl, I even got a brazilian hair treatment in the salon that did NOTHING. And let me tell you, I have very stubborn hair. I have 3B type curls and have always struggled to control it and make it pretty. My hair is coarse and fine and 50% frizz and the curls aren't uniform so it's not a good look. It takes an hour to straighten it and once it's straight it's so stiff that it doesn't look natural. I chose this product because it had such a high rating and because it seemed to be legit. I was very suspicious of all the products I looked at because even though they used so fancy name brand product on my hair at the salon it obviously wasn't strong enough to work on my hair (it did work on my cousin's wavy hair though, and took out almost all the frizz, my hair is just stubborn!!) Also, I didn't want to spend a ton of money on something that might not work so I picked this because it was a trial size. I only used about half of it so there's enough left over for another go around, it's awesome! I didn't even follow the directions and it still worked wonderfully. Let me tell you what I did: I didn't use a clarifying shampoo because I didn't want to go buy one, I just washed my hair really thoroughly and scrubbed at my scalp really good to clear away any dead skin or product. Then I rinsed my hair really well to best get rid of any soap residue. I blew it dry (a terrifying sight for my fiance!) and started to apply the product. WHEW the chemicals are strong. I would recommend doing it in a well ventilated room if at all possible because I kept having to stick my head out of the bathroom so my eyes would stop burning. I was not delicate about the application, I ended up putting too much in and my hair was def over-saturated but that's what I wanted! I let it sit in my hair for thirty minutes while I surfed the internet. I then took a fine comb and combed through my whole head getting rid of the excess product. The directions say to immediately start straightening on soaking wet hair and to me that just felt wrong and like I was going to burn my hair. So what I actually did was blow my hair dry again and THEN I straightened it. I took extra time on each section to make sure I sealed the product into my hair. It probably took an hour but obviously it was worth it. Then the gross part is that your hair is stiff and sort of greasy from the product and you can't do anything about it. You're not supposed to pull your hair back, you just have to leave it straight and down and looking yucky. The directions said to leave it in for 72 hours for very curly hair, but I had to shower after 24 hours because I had to go to work. So for the first three days I didn't shampoo it, just rinsed it and used a little conditioner, which I hardly even needed cause it worked so well. My roots are straight which is a HUGE deal as that is usually the curliest part of my hair. There is still a good amount of curl to it (because the directions say "for very curly hair leave product in for 72 hours" and I only left it in for 24 hours) at the bottom but it's pretty and manageable. The biggest difference is that there is practically ZERO frizz and the hair is SO soft. It actually looks so much healthier than before I did the treatment. I'M SO HAPPY WITH THE RESULTS! As I have half the bottle left, I will probably try again in 3 months or so and I will leave it in for longer to see if that affects the curl. I really don't feel comfortable with flat ironing soaking wet hair like the instructions tell you to but maybe someone else can let me know how it went for them and I will give it a try. I really think if I had followed the instructions to a t that my hair would have come out beautiful and straight. No regrets, I still love the results!

This product works great to eliminate frizzy hair. My hair type is 3b, left on for a little over 24 hours. Frizz gone. Easy to blow dry and straighten. Or let it dry and have soft curls. The smell is strong. Use a fan to blow the smell away from your face. Worth the price verses $300 for keratin treatment or Brazilian blowout. Lasts about 3 months, washing 2-3 times a week. Good luck!
