Keragen Brazilian Blowout Keratin Hair Treatment - Sulfate-Free Smoothing System for Dry, Damaged, Medium to Coarse Hair - Eliminates Frizz & Curls, Adds Shine & Strength (16 Oz)

Love this treatment, I have course, frizzy hair and used to use Trisola but this one is so much better. Yes there is an odor, I wear a cloth mask with a paper towel folded on the inside and it works great. The only times the fumes bother is when you blow dry it before flat ironing. I do my whole head and leave area around my face last, thats the part that effects me the most with the fumes. But the results are well worth it. I do use a ceramic flat iron brush which is so much easier to use. Just bought bottle for my daughter who inherited my hair. Went on air boat ride, hair got blown and wet and was still straight and frizz free after. Definitely recommend this product.

Best relaxer I have ever used. My hair was done by my mom who is a licensed cosmetologist. She was extremely impressed with my results. I naturally have frizzy, coarse and poorly defined curls. This product gave me the straightest hair I have ever had. After completing the process, washing and blow drying my hair no need to flat iron (which has never happened before). My only issue is the smell while blowing dry but the results are amazing!

I was lazy and put off this review, but it’s been about a month and my hair is almost as glossy & frizz free as when I first did the treatment. So I expect that next time I do it, the results will be even better!I naturally have a lot of wavy, frizzy, tangled prone hair. After using this product however, I don’t really have these issues anymore. It’s very manageable now, and I have less breakage. My hair is also very strong and straight. All my little flyaways & baby hairs do not curl up and look crazy in humidity anymore. Before I would use a ton of hairspray to try to tame the flyways, but the results could not even compare to what this product does for my hair.While using this product I personally do not wash my hair until I have to. Despite the instructions saying you can immediately. I like to wait as long as I can before washing.There is one downside though, my hair used to have a lot of natural volume. I could flip my hair a few times and have incredible volume. But now it stays flat unless I use a root spray. My hair also has difficulty with holding curls now even with styling products. Another issue is a lot of my wavy hair products I used before that worked well on my hair, now weigh down my hair a ton and no longer work for me. I also have to wash my hair more frequently now, I used to be able to go almost a full week without washing. My hair now gets noticeably greasy after 2-3 days.I figured I would mention this because I was expecting it to be more sleek, and shiny, with less flyways. But it actually changed the texture, appearance, and the way my hair normally acts. If you are a proud wavy/curly girl, I’m not sure if you want to use this because it may permanently change that for you!I personally don’t mind it because I hated dealing with my hair before, looking forward to my next treatment. I probably have a good 5 treatments left too, so it’s worth the price!Make sure to use gloves, and apply in a well ventilated area. Not only do you not want to breath in the fumes, but they can also irritate your eyes! Next time I do mine, I’m going to do it outside.Edit (follow):It’s now November 2023, and I’m still a fan of this product. The chemicals are very strong but I’ve done about 4 spaced out treatments so far since I got it. And the parts that are treated look different from my natural hair. I now have a long lasting Pantene commercial shine on my hair. Staying it has become a bit more difficult now because my hair is now stays straighter and is more “slippery” than normal. So it no longer holds a curl like it used to without either doing it overnight or using a lot of heat. Overtime it’s become a lot less frizzy and naturally more manageable. I also still have a good portion of the bottle left (about 6 treatments I would say!) The chemicals do burn the eyes though so I normally do this outside or in a room with the window/fan on with a mask because it’s intense. But the effect it has on my hair is just worth it to me.

I have very thick and frizzy hair. Using this product was easy albeit a bit time consuming. However, it was worth it! After using the product my hair was softer and a lot more tame. Did I still have to style it? Yes however, as mentioned I have unmanageable hair. But my styling time was cut down A LOT. Will definitely continue using. I will leave some notes:- Make sure you have A LOT of ventilation, this product has a very powerful and irritating smell. It is better to use this product outside during styling. My eyes were irritated from the fumes and the smell was awful.- You may have to wash your hair more frequently. My hair usually takes a good 4 days before it’s oily however with my treated hair, my hair gets oily rather quickly (2 days)- If you like to curl or blow dry your hair, your hair may not retain the style as long as it did prior to the treatment. It will fall a lot more quickly.

I decided to try this treatment after a pricey keratin failure done at a salon, and I have zero regrets.I have coily hair - not the tightest coils, but tighter and naturally drier than wavy or curly hair and I am completely pleased with the results.Caveat: if you have tight curls or coils and want to achieve a dead straight effect at home, this may not be for you, unless you have that type of skill with a flat iron (I don't). For me, the result was a loosening of my curly texture, to the point that my hair is so much easier to manage, whether I want to wear it curly of blow it out. (I imagine that a professional blow out, after having done this treatment at home, would result in a super straight look.)I followed the instructions closely (almost dying of the fumes, I'm not gonna lie) and after the flat-ironing process, I washed and conditioned with the sulphate free products from this same line. My hair felt like a baby's hair! It's the softest and most manageable it has ever been.I am definitely sticking with this treatment and highly recommend it if you are trying to achieve a looser, more manageable texture.
