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

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

I have used this product several times. Last about 8 weeks and is gentle on my hair. I was going to the salon but I enjoy the price and the mildness of the treatment.

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.

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.

So yes this product has no fumes but you are definitely given other downsides in place of that. The bigger issue with this is the smell. It will linger in your hair for days. The results were also a little underwhelming compared to a regular keratin treatment. I would only recommend if you absolutely cannot tolerate the fumes from the regular product. That being said if you are sensitive to smell you will not enjoy this.

So far so good...I am a licensed hairstylist over 20 years and I was looking for a formaldehyde free keratin treatment. I have tried others in the past...chi enviro etc. I have used the ones with formaldehyde on others as well, I just don’t like the fumes and chemical exposure. I left the product on for 20mins bc my hair is color treated. I rinsed well, dried hair fully, and then flat-ironed. My hair was like the hair of my youth! So soft, shiny, and healthy looking. Just unbelievable. I woke up this morning and hair (in the words of zohan) is still silky smooth. Will be truly testing when it starts getting humid, as I live in the south. That will be the true test!

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.

Did not work at all

It doesn’t soften the hair. My hair are not very frizzy so I was expecting good results but it didn't make any difference to my hair! They are still frizzy! I also bought very expensive shampoo and conditioner of the same company. It’s such a waste of money and time. Only positive thing is, it doesn’t have that pungent smell.
