    Best hair purchase I've ever made!
  

*by B***L on Reviewed in the United States on September 8, 2017*

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.

    Fantastic product!
  

*by M***E on Reviewed in the United States on May 11, 2018*

If I could give this product 10 stars, I would. I had been getting Brazilian Blowouts (BB) in a salon for years at $200 per treatment. After BB stopped using formaldehyde, their treatments were basically useless...lasted less than one month. This product is fantastic! It contains formaldehyde, so use with adequate ventilation. It works WAY better and lasts WAY longer than the professional treatments. I can't begin to tell you how happy I am and how much money this saves me! I waited to write a review until I had gone through 2 complete cycles with this product (I'm now ready to apply it for the 3rd time). I wanted to make sure that it didn't just work well initially and would last. I'm happy to report that it lasts between 4 and 6 months. It all depends on how fast your hair grows. The treated part of your hair is still fine, but all the roots all over your head grow out curly/frizzy, so your hair starts to look bad again. I can't say enough good things about this product. It is probably my single favorite Amazon purchase of all time, and I buy lots of stuff!

    Very effective, but quite toxic
  

*by J***A on Reviewed in the United States on September 21, 2017*

Works really well, I've washed my hair about 4 or 5 times since using this and it is pretty much straight (I started with 2b-3-b curly hair). When you do the treatment it feels quite toxic; a lot of fumes come out when you blow dry and straighten, so def do it with windows open and if you have a face mask use it. I didn't and it was hard to breathe haha...but totally worth it. Hope it lasts for a few months! I have pretty thick hair, below shoulder length and one bottle of the smallest size was enough for my whole head. Weird instructions though, they're in broken English for some reason which is kind of worrying but oh well... it works.UPDATE: 3 Months in and my hair has slowly become wavier again, but it is amazing how long it has lasted. Initially, my hair dried almost straight, and over time it has begun to get wavier and wavier. Still nowhere near as curly as it was 3 months ago, and it is waaay easier and faster to straighten. I will definitely be buying more of this stuff and I definitely recommend it for girls struggling with the burden that is curly hair.
