Exactly the subtle gentle change that I was looking for.
I wanted a subtle change and this product worked well for that. I liked how my hair looked and felt when I was done. My hair is straight and smooth to the top and front (the crown), and wavy to the sides and back, and at the very back of my neck gets very wavy. So what I did was apply the product for 20 minutes then washed it off and used the conditioner for 10 minutes then rinsed that off, then blow dried and flat ironed. Super smooth results. When I washed my hair for the first time as it air dried I could see a definite loosening of the wave patterns to the back. So it’s gentle and if you like to wash and air dry like me you will enjoy the subtle difference it makes. You can also flat iron if you prefer that look. I just wanted to be able to wash and air dry (and not flat iron) and not have to deal with any frizz. As far as this goal went (no frizz) it was a difference, but I would have liked a more dramatic change there. So what I did after a bit less than a month is use the clarifying shampoo again and this time leave the product on for the full hour (more time for the parts to the back) This way it was more effective. The parts of my hair to the front, I stayed with the 20 minutes time frame… so basically I put it on the back, then waited about 40 minutes then put the product on the rest of my hair to the top / crown that is not wavy / straighter and that worked well for me. I am the type that washes my hair often, so for me, I would probably use this maybe every 4 to 5 weeks. I have seen no signs of damage whatsoever to my hair which is great. Basically, I am very pleased with this product overall. I think this Formaldehyde free version is a good option for me because I am definitely not keen on that formaldehyde smell and / or having to leave a product that has chemicals in my hair for days and days. In the past I did try a traditional keratin (with formaldehyde) many years ago... but I didn’t like the process - the smell - or the results AT ALL. I didn’t like the chemical smell …or the “stick straight” look. I prefer a more natural / softer bounce to my hair and this product definitely achieves that. I can use it and flat iron for that sleek look… or ….. I can wash and let it air dry as I wish - which is what I usually do. When I let it air dry I get a really nice effect … more natural looking than that “stick straight” flat ironed look. This is my preference and this works for me. For those of your that like the "stick straight" effect - consider the chemical version….although I haven’t tried this brands formaldehyde version… so I can’t say how effective it is. I definitely do recommend this brands formaldehyde free version. It works for me and it gave me exactly the effect I was hoping for. Fuss free lower maintenance hair that I can just wash and air dry and go..! I haven’t tried their shampoo and conditioner as yet because I already have a bunch of other sulphate free shampoos…. When mine are finished I definitely will try theirs. I did try the smooth polish / oil but not on the first application. On that first time I didn’t use the smoothing oil… I used it on the second application a few weeks later. I like it. It definitely adds shine and I would also buy this again. Overall I am VERY happy with this purchase. Maybe I will also upload some pics next time I use it. I do think the directions from the manufacturer could be a lot clearer. I found there was one set of instructions on the bottle and another on the website. That needs to be addressed. If you found my review helpful, click to indicate that. I wish other people would give reviews - honest reviews - that way it would make shopping easier for all.

Less frizzy hair
This is my first keratin treatment, so I wasn’t too sure on what to expect. I have really really puffy 2c hair, and if I don’t use curl products it will be insanely puffy. My hair is also really long and goes to my mid lower back. Even when I use my hair straighter usually, it will be mostly smooth but with frizz on the ends. No matter how much I straighten it. The only thing that worked to smooth it out before was color wow. I applied it like how the instructions said, and at first I was blown away! My hair was so so straight, like Asian hair straight. No frizz in sight! This was the first time in my 21 years of life that my hair looked so perfect and straight. Also, there were barely any fumes. I didn’t notice my eyes burning and I didn’t smell anything bad. I left my hair straight for 2 days, and then I washed it. I know you’re supposed to blow dry your hair to help it, but I let mine air dry. I definitely still have waves, and still have frizz. But it is significantly better! Like looking at my hair now, I would say it’s 2a-2b, and about half as frizzy as it was before. I could totally go out of the house like this, and I didn’t even put any leave in conditioners in it like I usually have to. My hair was damaged before from straightening it almost every day, and looking at the ends I only see a couple more split ends so I don’t think it damaged it much worse. Also, for the process I didn’t use their shampoo or hair mask which maybe would have helped. I just used suave clarifying shampoo, and I used my Eva nyc hair mask. Also, my hair is so much less tangled. Overall, I would 100% do this again. It didn’t get straight like I was expecting, but it cuts down my styling time so so much.

Very good product, my hair was left nicely straightened without being damaged. My hair is curly and it straightened it quite well.

Like a hair salon! — Long review!
This worked just as good as the keratin treatment I get at a hair salon. I decided to do it myself because I couldn’t pay $230 at the salon. This was a fraction of the price. The process: Took me about 3 hours from washing my hair to being completely done. That’s usually how long it takes at the salon. This is how I did it. Washed my hair with my regular shampoo and last wash with clarifying shampoo from this brand. Towel dried and brushed it to detangle, with no product. Separated my hair into 4 sections and started from back to front on each side. Got one side saturated with product using a brush (like the ones for hair dye) not touching my scalp (it will be itchy if you touch your skin) once the section was done I put a timer for 15 mins (I have thick long wavy very frizzy hair) did not clip my hair up because it would make product touch my skin. Then went on to the next section. Once I was done with the second section I looked at how long the timer had left. Then waited and once the timer was up I went to rinse the first section and put a timer for whatever time the second section had left (that way I didn’t go over the 15 mins) then went to rinse the second section and repeated the process with the other side of my head. Once I was all done I did one last rinse with all of my hair (I rinsed in my kitchen sink but you can do it wherever it’s easier, I didn’t want to do it in the shower so the product wouldn’t spread all over my body). Then I used the hair treatment from this same brand and let it sit for 10 mins. Rinsed it and blew dry my hair. Once my hair was all dry I used my flat iron on the temperature before the highest and took 1 inch sections and did 4 passes on each hair sections. The results: INCREDIBLE! It was hard work but it was so worth it. My hair was so silky smooth and shiny. Super straight. It did smell like the chemicals and didn’t go away until I washed my hair again. When I washed it I let my hair air dry and it was a huge difference from before getting the treatment. My hair is not as wavy anymore but not straight either. It feels very soft and the best part is that like 95% of the frizz is gone! My hair feels so healthy now and I have enough product to do another treatment so for me who has thick, long and a lot of hair I can do 2 keratin treatments with one bottle.

I have extremely thick very long 3C intense curls. I was very impressed.
Really incredible results and so easy to use! I have 3C curls so I divided my hair into fourths and applied it. It's creamy and thick so I bought a special brush for application of hair dye, but I didn't even need it because it was so creamy I could apply it with gloves and my hands. After I applied it to my entire hair, I put the timer on for 40 minutes. Then I rinsed it out with just water thoroughly and blow dried it; immediately my hair dried very fast and was easy to blow dry. It took about half as much time as it normally would to blow dry it dry. I used to blow drying brush, then I flat ironed it in 2 inch sections and to be honest even that was quick. I only had to pass the flat iron maybe three times and I noticed my hair was so silky! It took perfectly, and my hair can still hold a curl with a curler. The very next day there was a little bit of misty sprinkling rain & fog - June gloom, and I was outdoors quite a lot all day but my hair never once frizzed up (unheard of from me). I absolutely love it. It's incredible. I used to pay almost $400 to get this done and I still have half a bottle left. ****4 month update: this is still excellent! I have long thick hair and I got 3 uses out of this bottle. It always makes my hair silkier and more manageable/easy to blow out. I love this product.

Does it work? Yes. Does it smell? Also yes.
So I used this product, and I found that it’s definitely help my hair feel more manageable, and help a bit with how my ends are dry and a bit damaged (though, this was my first use of the product, so take that as you will). I only specify cause A) I didn’t use heat on my hair afterwards, cause my hair’s already damaged, and B) it didn’t change the looks, but that wasn’t my focus, I cared more about trying to prevent some of the dry fraying. However, the smell (which smells like you tried to cover up a medicinal soap with potpourri) is not only fragrant, but it lingers on other surfaces, including towels and bathtubs, and it didn’t go away until I cleaned my bathtub. So, if you’re sensitive to smells, then I wouldn’t recommend this, cause then it’ll be within the vicinity until you clean your towels and your bathtub, along with your hair. Otherwise , it works pretty well.

Buena calidad
I was a bit nervous trying this at home, but it turned out great. My hair is fine and tends to frizz easily, and this treatment made it noticeably smoother and easier to manage. It didn’t feel harsh or overly strong, which I liked. The results looked natural, not flat or greasy. It takes some time to apply, but the outcome is worth it. My hair feels healthier and looks more polished.

Keragen la mejor opción
Desde la primera aplicación, el cabello se siente mucho más suave, brillante y manejable. Ayuda a eliminar el frizz y deja un acabado liso o más definido, dependiendo del tipo de cabello. Además, contiene ingredientes como keratina y colágeno que ayudan a reparar y fortalecer la fibra capilar.

Natural waves not straight hair!
Is good if you want to relax curls as it does not straighten your hair fully (I’ve used just once) I really like it the result looks natural and my hair is not damaged. The process is also easier than other keratin treatments as you have to iron it after rinse it out before.
