Review: 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.
Review: 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.
