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)

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!

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.

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 really liked the convenience and smell, since I’ve tried way stronger smelly products before, it’s very easy to work with and the product feels very light and not stick. After the first wash it looks and feels great, super smooth and straight, but the more you wash it seems to lose its strength. I wash my hair 2-3 x a week and it has not even been 3 weeks since I’ve applied it, it’s pretty much back to what it was. I will keep trying to use it in a regular basis, probably once a month to see if my hair gets used to it and I can have it to keep holding it for longer.

I never leave reviews but this product is so great I had to. I am not a professional but I just the product as instructed with the exception of leaving it in for 24hrs vs immediate wash. I know some people leave it in for 72 hrs but it was a little too heavy for my liking to leave it for that long. It does have a very strong odor when blow drying and straightening and it did make my eyes water a bit. Be sure you use in a ventilated area. Also, I wore a mask which helped with fumes. With all that said, my hair has not been this healthy and manageable in YEARS! I have damaged my hair severely the last few years and it was a hot mess but now i blow dry and it is frizz free, breakage free and so soft without straightening it!!!! Be sure you use a shampoo and conditoner sodium cloride and sulfate free for the product to work it's best and last! If you are debating trying this just do it! You wont be sorry I promise. I wish i had known about this product sooner! It used to take me over an hr to get ready now wash blow dry and done! Plus my hair has never looked and felt so good!

marketed as a keratin treatment but contains formaldehyde. I knew something was wrong when I started do the treatment because of the smell. It’s SO strong. But I still continued because my dumb butt didn’t read the ingredients. I was like well maybe this one just smells strong but no my gut was right. I lost all the volume in the hair and let me tell you my dandruff was so bad. My hair was so healthy from a formaldehyde free keratin treatment I had gotten a while back and it lasted 8 months. It started to wear off so I decided to try a new one not realizing this actually contains formaldehyde. The ends of my hair are now fried and damaged and my volume and waves are all messed up. If you want pin straight hair do this treatment but if your just looking to tone down frizz stay far away from this it does not make your hair healthy girl it will mess it up. It lasts a month if you take care of your hair, if you don’t it won’t last more than 2 weeks. So sad about my hair but also my fault for trusting marketing. This stuff is sooooo bad for your hair. (I’m writing this review 3 months after I did this treatment because I decided to see what long term results look like. It’s so not worth it.)
