KERAGENBrazilian Keratin Smoothing Treatment, Blowout Straightening System for Dry and Damaged Hair, Formaldehyde Free, 2 Oz - Eliminate Curls and Frizz, Fine to Medium Hair

I didn't follow the directions. I did my own experiment and it WORKED. My hair went from 3B/4A to 3A/2C (I have a naturally inconsistent curl pattern. My hair is also so much healthier, softer, and more manageable. My hair wouldn't get fully straight before and would frizz out, now I can get it pretty straight and there's much less frizz.What I did: Applied product to dry hair and combed it straight in sections until it dried. When it was slightly damp, I straightened it using a flat iron. It straightened to be so shiny and straight. I left it like this for a couple of days and straightened it as needed. When I washed my hair I couldn't believe the results. These were better results than when I got an actual Brazilian blowout. My hair was soft and healthy. I let my curls dry without product and they were well-defined. I would highly recommend trying this. Read through the comments and check out what others have done.

Very good

This product doesn't do anything to your hair but leaving a horrendous smell for months each time you wet it. I tried instead of the regular Kerating treatment and it's been a disaster. All that besides the fact that they used to have the wrong instruction in the product description (they removed them now) and I was about to use the flat iron with the product still on my hair!!, I've would have destroyed it because this product it all greasy, thank god, I read a review from someone who noticed the problem and didn't do it. Don't use it unless you can take a rotten burning egg smell every time you wash your hair for months to come. Stick to the regular formula, that doesn't smell and softens your hair for months, I just use a little bit of it.

So far so good, I like that this product smells good, vs like chemicals. I washed my hair 3 times with clarifying shampoo. Then applied the product as if I was applying conditioner. I combed it through really well. Let it sit for only 20 minutes. Make sure to not scratch your head before hand so your scalp won’t tingle. I rinsed the keratin treatment out. Added frizz buster serum by fantasia. And blow dried. A flat ironed using moderate heat (don’t over do the flat ironing and heat) you don’t want damage. Listen to your hair. My hair is really smooth and I don’t have to flat iron everyday.. Do a test patch. Don’t leave product in too long. I did that once. And my hair was shedding and scalp had extreme Dandruff. But this formula seems to be perfect. And I have 4c hair, and my hair blends so well with weaves now and I feel it’s better protected since I don’t have to flat iron sooooo much. And plus it’s temporary. Like a miracle in a bottle, Will update.UPDATE:. Still love this product, but 20 mins isn’t enough. I have 4c medium density hair. And I like the results best when I let it sit an hour. Only the ends of my hair is reverting now (only bc of intense steam and heat from the air) it’s been 1 month so I will reapply happily. (My roots stayed straight thru sweat and all). (The ends are always most Porous, so the steam got them first. I used big Velcro rollers at night to keep my hair safer. I only got a little dandruff (after 1 month of having hair straight) , I combed the flakes out, and apply oil to scalp and the dandruff subsided. I’ll use tea tree oil next time. I get huge flakes from regular keratin treatment (bc of the protein irritation on scalp) which is why I like this one better. This treatment is great for winter bc it’ll last longer

It did make the beard straighter, but not nearly as perfect straight as some people seem to achieve on their scalp hairs. It's possible that I did not do enough passes with the flat iron, or that i need to do a second treatment. It's also possible that a beard is just harder to tame for any product. Not sure. I am on the fence as to if doing this kind of treatment periodically is easier than using a heated beard brush daily for 2 minutes to keep things relatively straight. Also there was a bit of a chemical smell on the beard for a few days that shows up after getting it wet. May try the original version with formaldehyde later on. In any case, this product certainly had a noticeable effect.

Exelente

So the good is that the smell during the blow dry is MUCH more tolerable than the version with formaldehyde. But the bad is that it doesn’t DO much, and that’s the whole point of the product :(My frizz is only barely reduced, hair is not wash & go like it is with the Forte version. And my curls are slightly loosened, but now just look limp and weird, they aren’t gentle waves or anything desirable.The worst part is that now when my hair is wet (I’m 5 shampoos after application) it has a very stinky smell. Vaguely reminiscent of standing sewer water. Oh, and this product stripped the color / lightened my hair about 1.5 levels in a brassy direction.I would not buy this version again.

Forte did wonders for me although it did not last as advertised I decided to give the formaldehyde free version a shot. I liked how simple it is to apply this product compared to the forte version. Unfortunately this version did not do anything for my hair. It would've been fine even if my hair didn't turned out straight as long as it was soft, silky and manageable but none of those my achieved.
