KERAGEN Brazilian Smoothing Keratin Hair Treatment, Frizz Control, 16 oz

First off, all the negative reviews in here which wasn’t a lot made me laugh. From not using gloves, not using heat and her hair staying curly to scalp being on fire to the keratin not lasting. My favorite one was someone complaining about the formaldehyde. This bottle does not say formaldehyde free anywhere on it. This brand I believe has a Formaldehyde free one. Just takes a few seconds to read. If this is your first time ever doing a keratin treatment on yourself, it is important that you read the directions and follow them to a T. (NO EXCEPTIONS). I’ve done keratin on myself before with a different brand I don’t have access too anymore because I need a cosmetology license. I only have a full specialist one. I did like that this was available on Amazon and it’s for professional use and doesn’t require a license to purchase. On to the keratin…. You must have clarifying shampoo. This strips all the oils, minerals and dirt your hair collects over time from all the hair products and even shampoo and conditioner you use. Wash your hair two times. After I washed my hair, because I bleach and dye the front of my hair and I like having that fresh color look, I went ahead and put my dye on my hair. I use pulp riot and artic fox which are both semi permanent. Once my hair color was done sitting, I washed only this section of my hair with cold water while the back continued to air dry. I then towel dried my entire hair. The instructions on the bottle says to section your hair into 4. The only thing I did different because I’m so particular about each strand of my hair was. I decided to put the keratin piece by piece. When applying it you don’t have to worry so much about the fumes. That comes with the heat. I did this is my bathroom which only has that small window to the outside. I opened up the window and had a small desk fan blowing at my face while I put this on. Just so I wouldn’t be breathing anything directly. I used gloves, a fine comb brush and a dye brush. For each small section I grabbed, I made sure I did not get anywhere close to the scalp. You scalp doesn’t need these chemicals on it. Apply the keratin an inch away from the scalp. At least a horizontal finger away from the scalp. I then brushed it with the fine comb to make sure every strand had product. I also wanted to ensure I did not put too much product. After doing my entire head. I sat on the couch to relax for 20 mins to let the keratin sit for a bit on my hair before putting heat over it. Fine/Colored Hair: 20 minutes Medium/Coarse Hair: 35 minutes Virgin/Resistant Hair: 40 minutes My hair is not fine, it’s on the coarse side but since it is colored I did the 20 mins. Headed back to the bathroom. Made sure the window was still open, a big fan on the floor by the door blowing TOWARDS the window and the other small desk fan on the sink. Grabbed the blow dryer and I made sure whatever section I was going to be blow drying, that the heat would be blown the same direction as the fans were blowing which was towards the window outside. This is of course what helped ME not to inhale fumes or my eyes get watery. I didn’t blow dry every section perfectly cause the flat iron is what’s going to give you the straight perfect hair we curly haired girls want. After blow drying I then went to ironing my hair, small section by section. Again making sure the direction of the fan and fumes went with the air. Sometimes I would hold by breath for a few seconds if I was doing the front of my hair. Not because I had too but just to be safer with this product and inhalation. If I ever felt I needed some fresh air, you can stop and step out of the area you’re working in and go take a quick break. I didn’t feel I had too since I had the fans right on my face. If anything I would put my face closer to the fan to get fresh air. Once done keep in mind not to tie your hair or put any clips, etc to it. It will leave those indentations after you wash your hair in 2-4 days, So just don’t! I style my hair by doing side bangs, so that’s how I blow dried and ironed my hair. You should do your hair accordingly. Once done it’s normal to feel your hair a tiny bit…. I don’t wanna say greasy because it’s not greasy but like you have a bit of a shiny product in your head because, well…. You do. The longer your hair the longer this may take. The bottle also brings enough to do several treatments. I should have enough for the next year or year in a half. This is not an exaggeration. This depends on how well you maintain your hair and re do the treatment. You shouldn’t need to redo it for at least 2-5 months. Again depending on your hair type and how you maintain it. If you don’t use sulfate free shampoo and conditioner, this won’t last as long. Same if you wash your hair every single day. If you don’t use sulfate free shampoo I would guess this would last perhaps a month or so depending how much you wash your hair. It’s not like the treatment is going to wash off completely if you don’t use sulfate free on one wash. With this being said read the labels from the shampoo you buy. I have bought sulfate free labeled shampoo that has sulfates in it. Your ingredient list on the bottle is your bff. Check for names like Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES), Ammonium Lauryl Sulfate (ALS), or Ammonium Laureth Sulfate (ALES). If you don't see these, the shampoo is likely sulfate-free. I usually don’t wash my hair for 48-72 hours after the keratin but when you do wash it, you’ll notice your hair dries quickly and looks just as good as day one. No frizz under this Florida heat and humidity. I normally do keratin on my hair every 4-5 months and then I’ll take a break after a while. I have attached pictures of my front colored hair and the back for reference after the keratin and of course my natural curly hair. Definitely would purchase this product again. Don’t let the negative reviews scare you from having great frizz free hair. You have to know what you are doing and again, read Instructions!! Having a fan blowing towards your face is your best friend during this process. No watery eyes or symptoms of burning for me while I did this. ❤️❤️

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 3a hair and have had to straighten my hair practically forever so after seeing some videos about this product i decided to give it a try and i will be using this product from now on. usually washing/blow drying/straightening my hair is a 2ish hour process and now i can hop right out of the shower, let my hair air dry or blow dry and touch it up with a straightener in 20 minutes. my frizz is gone and my hair is about 90% straight after one use. hair looks shinier and my hair doesn’t feel damaged after use. the application process took me about 3-3.5 hours from initial wash with clarifying shampoo, application and sitting time, blow drying and straightening. blow drying is a long process and definitely stinks and can burn your eyes so good ventilation and a decent sized room i would definitely recommend. but overall, i found the process 100% worth it. i bought the smaller bottle and i have about 20-22 inches of hair and i still have enough product to do this 3-4 more times. i dont think i would recommend for children because the fumes are very strong.

First off let’s start with saying this definitely works for frizzy hair. I got the Brazilian blowout done before doing this treatment and I was amazed and loved it but didn’t love the cost. This works exactly the same, but better I feel like with the Brazilian blowout made my hair super straight and flat. I didn’t really like how flat my hair was. This one controls the frizz and doesn’t make my hair so flat it still keeps my volume. I will say it does have the same smell as a Brazilian blowout so be aware.I was doing it in my hair bathroom and I couldn’t hand it with the first strand , I had to do it on my balcony because the fumes were burning my eyes and making me cough. However totally worth it even if it doesn’t at that moment because of the fumes lol. Pro tip use the revlon one step volume brush, it made it was easier and faster the dry my hair with the product . 1 month update since my last review, I still like the product however it does not last more than a month. My hair is getting frizzy again unfortunately. I think this product would be great if you’re going on vacation or something and want less frizz. I would still buy it again , I just wish it lasted as long and the Brazilian treatment did.

used this product on my sister and she loves it!! it looks beautiful. i’ll def be doing this on myself too but just be careful when using it bc the fumes are insane. my eyes kept burning so bad. i recommend using safety glasses and a mask when doing the treatment. 10/10 product though. i definitely will be repurchasing!!

​This product absolutely delivers on its promises, but you have to be prepared for the process! ​If you follow the instructions exactly as written, the results are incredible. My hair looks fantastic, and the effects easily last anywhere from 3 to 5 months, which makes the effort well worth it. ​The only major downside—and the reason I’m giving it 4 stars instead of 5—is the fumes. They are incredibly strong and harsh. They made my eyes water instantly, and the chemical smell is just too intense to handle indoors. I actually have to blow dry my hair out on the balcony just to make it tolerable. ​If you are going to use this, I highly recommend doing it in a very well-ventilated area (or outside if possible) and taking your time with the steps. If you can get past the rough application process, the long-lasting results are totally worth it!

NOT FORMALDEHYDE FREE. this comes up when you search for formaldehyde free keratin treatment and it is not. I didn’t check the ingredients because I already searched formaldehyde free so why wouldn’t it be right? WRONG. The fumes on this are so bad. I don’t know how anyone can tolerate it. I don’t use air conditioning. I had all my windows and doors fully open with 3 fans on full blast and it was still burning my eyes while I was applying it. I pushed through, but once I started blow drying, it got 10x worse. My nose started burning and running, and when I tried wearing a mask, it actually made it worse. My eyes were red, burning, and watering like crazy. I tried to push through but I just couldn’t. I had my eyes closed, held my breath and it was still burning my eyes and nose unbearably. So I ended up with half my head blowdried and the other half I just rinsed out. The side I didn’t blow dry feels nice and soft while the other side feels super rough and dry. I will update after a few days. For reference: My hair is 3b 3c. Has been bleached so my natural pattern is more of a 3c 4a. I haven’t bleached my hair in over a year. I also wanted to mention that I have a pretty high pain tolerance I’ve been bitten by wasps, get migraines, endometriosis cramping…etc. but I cannot describe the irritation of those fumes and I would rather have all those other things at once than ever go through that again. Definitely avoid this and try to find one that is formaldehyde-free.

Título (en inglés): Silky, Smooth Hair After First Use English review: The Keratin Smooth has impressed me. From the first use, my hair felt softer, easier to manage, and with less frizz. It has a lightweight texture that doesn’t leave the hair greasy or heavy, and the scent is pleasant without being overpowering. After several weeks of use, my hair looks healthier, shinier, and more salon-like. It’s great for dry, damaged, or frizzy hair because it improves texture and makes styling much easier. I highly recommend it for regular use, as the results become even better over time.

I have incredibly thick and curly hair prone to frizz, I have tried a few products and this has been by far the most effective. My tips are to ensure the space is extremely well ventilated, because the fumes from this are really strong and the chemicals in the fumes are not good for you. I wore gloves, ear covers, a face mask, a towel covering the back of my neck, and if you have sensitive eyes wear goggles as it does make your eyes run when blow drying/ straightening. You need a clarifying shampoo to use first (skip conditioner), and then work the product through your damp hair in sections, I left it on for an hour for full effect (put hair in a shower cap and chill for an hour, there weren’t any fumes until I had to brow dry so it was okay) and then blow dried on a cool setting (less fumes on a cool setting) before straightening with my GHDs (you need very hot straighteners for this to work). I straightened each section of hair 5 times. The thing I like about this product is that you can wash it straight away after (normally you have to leave it on your hair for 3 days!) so it’s nice to know that you wash all the chemicals out after the treatment is done (use sulfate free shampoo). You can feel the change of the texture of your hair even when wet, and it’s so much quicker and smoother to blow dry. Also the bottle is huge and you only need a small amount per treatment so it’s going to last me ages… This product is the best I have used, however note that it’s not formeldyhyde free (which is probably why it works so well!) so use precautions to be safe with it (use in well ventilated area and avoid contact with your skin.). You do get amazing results with this.
