Clarifying Shampoo with Brazilian Keratin Treatment and Intensive Hair Mask KIT Tratamiento de Keratina Alisado 120ml. Packaging may vary.

I have tried this one and the Keratin Research. Here’s a quick comparison from my personal experience: Kerazon: Smell was WAY stronger than Keratin Research. I had read the reviews of others saying the smell was bad, but I thought, “I’ve done this before with the Keratin Research, I will be fine” but no, BELEIVE THEM. Like my eyes and nose were burning, hard to breathe, barely got through the process. At one point I got super dizzy and had to take a break. Lasted about 2 months for me. Maybe this was due to the fact that I couldn’t run the straightener through as many times because I was just trying to hurry up and finish due to the smell. But it didn’t last as long for me. It did give me sleek, soft hair, but I still had to run my straightener through a few times a week. This one is more for pin straight hair in my opinion, less for frizz. Keratin Research: Smell was far more bareable. But still present. Results lasted way longer, about 3-4 months. More for frizz reduction rather than pin straight hair, which is what I personally was looking for. It did still straighten my hair but I didn’t have to straighten it after most of my washes like I did with the Kerazon. Overall, I prefer the Keratin Research. But if you want super pin straight hair at any cost, go for Kerazon. Make sure to get like goggles and a mask if you do get Kerazon. You absolutely HAVE to be in a well ventilated or big space. My bathroom is small, I opened th window and ran a fan and still almost died lol. As far as damage, I personally did not experience that with either but everyone is different. Just don’t apply it directly to your scalp or at least a lot of it for a long period of time and you should be fine if you have relatively healthy hair/scalp.

My review will have some details, so I hope you find it helpful. My hair is curly and thick, so I've always treated it and gone to the salon to maintain it. Last October, I dyed it and got a treatment for a party, and since then, I hadn't done anything else to it. Since everything has gone up in price and the treatments I get are expensive, I decided to look for another way to properly care for my hair without damaging it and without spending the same amount of time I do at the salon (5 hours). I decided to look on Amazon for different keratin treatments that were as good as the ones at the salon. I read a lot of reviews because I usually compare prices, and that way I can decide if the product is worth the advertised price. I normally spend between $80 and $150 per treatment every three months, and I wash and dry it at home since I have everything I need to style it. I found this Kerason product, and it seemed to have the same technique and process they use at the salon (the difference is that you have to straighten it, wash it again, and dry it all on the same day). So I bought it and did my hair myself, just like at the salon. I ordered the $69 treatment because my hair is shoulder-length and the product was 2 oz, but I think next time I'll buy two treatments to make sure I don't run out. (But I used a tip I read, and the 2 oz was enough for all my hair.) Since I already had to dye my hair, I did it first because the instructions say to dye it first and then do the keratin treatment. Then, another day, I washed my hair again and used the clarifying shampoo that comes with the treatment, and I blow-dried it completely. Then I started the keratin treatment, dividing my hair into four sections. (TIP) Since the bottle was 2 oz, I poured 1/4 of the keratin into a bowl and mixed it with a little water, as the product is quite thick. This allowed me to treat all of my hair, right down to the ends, and you should wear gloves until you're ready to straighten it. The product has a smell, but it's tolerable. You should wear a face mask, as it will irritate your eyes quite a bit, so you need to be in a well-ventilated area if you want to do the treatment properly. After finishing the keratin treatment, you should blow-dry your hair on the cool setting and then straighten it completely. Since my hair is quite thick and I realized I'd never finish with just the straightener, I used my blow-dryer on the high heat setting to complete the process. As I had already been drying my hair for four hours and had other things to do, I decided to leave the product in until the next day (my hands were sore from drying it so much). The next day, I washed it and used the conditioner that came with the product (I used a generous amount). I waited 5 minutes and washed it again, then slowly started blow-drying it to achieve the desired result. Finally, I straightened it and finished with some salon hairspray and hair drops, then styled it (I put on a hairnet and slept until the next day). When I woke up for a doctor's appointment, I was THRILLED with the result! I honestly didn't think I could get the same treatment at the salon for $150 and get such great results for less money—$69! In the pictures, you'll see how shiny and fresh my hair looks. The best thing about keratin treatments is that I can work out, and even if my hair sweats, it still looks great, and I don't have to wash or straighten it. I will definitely repurchase this product, and I hope my experience helps you! 💇🏻‍♀️📌

TLDR Version: My hair is long, thick, and 'crinkly'. This is my second time using this product and the results are awesome and long-lasting. Use in a WELL ventilated room. You won't think the product smells bad at first, and it doesn't. But then it hits you and there is no excape. If it gets really bad, so outside for a few minutes and let your space air out. I used about 3/4 of the shampoo (washed twice), the entire 4 oz bottle of treatment, and the entire bottle of hair mask. If your hair is longer than mine you may want to get two sets. Tip: Do NOT wash your hair for 3 days after the treatment and use a quality Keratin-treatment specialized shampoo when you do. Using regular shampoo immediately after the treatment will cancel all your hard work and you won't get great results. Long version: If you have hair like mine, you know it's a struggle to manage. From fly-aways to frizz to always looking like a hot mess, I understand the pain. Flat ironing helps but who has time for all that? I dreamed of being able to "wash and go". Salon options were out of reach because of cost and time, so I tried this home option without expecting much. I first used this product in March of 2022 and OMG, I had incredible results. The process took FOREVER - from blow drying my freshly washed mop to brushing on the treatment to blow drying it again using the cold setting to flat ironing every strand. My arms were jelly, my nose was runny, my eyes were tearing - but I had beautiful, straight, and flowing hair. The treatment lasted well over 9 months; after that I started to notice more and more frizz returning and my hair started to tangle more. Time to set aside a day to do it again but I did it a little smarter this time around. After washing my hair with the shampoo, which basically strips it down to a rats nest of straw, I let it air dry until it was damp but not completely dry. The first photo is what my hair looked like after the wash. I then parted my hair into 8 sections (which was difficult to do being that my hair was extremely tangled) and using gloves, dumped the treatment into a bowl and used my fingers to spread it through each section, followed by the comb to make sure each strand was covered. So much quicker! The instructions say to use a blow dryer on a cold setting to dry the hair. Um, hello? It took me a good 2 hours to get my hair dry last time. Cold air + long, thick hair = HAHAHAHA, nope. This time around I planned in advance - I let it air dry as I worked (desk job, work from home). This might not be an option for you so plan on spending half the day watching TV or whatever takes up 5-6 hours. For the flat ironing, I did it per usual. I don't have expensive flat irons; mine are 1" and 2" Remmington brands from Walmart that I've had forever. They only go up to 430 degrees so that's what I used, going over each little section multiple times. Your hair will get VERY hot and smoke a little as you flatten your hair into submission. Although the instructions say that there is no wait time before rinsing, I did wait about 15 minutes. I rinsed the treatment out of my hair and applied half the bottle of the hair mask, brushing it through with a comb. Then I applied the rest of the bottle by working it through with my fingers; wrapped my hair in a towel, and rinsed again an hour later. You can rinse it out after 5 minutes but I had a conference call and decided to wait. After rinsing, I towel dried my hair, combed it, and let it air dry again. The second photo is it fully dry - no product, no flat iron, nothing. Exactly how it looked and felt last time I used this product. Now the 3-day timer begins - the instructions don't say this but it's best to wait at least 72 hours before getting your hair wet (even sweat) or washing. Don't use any product or accessories in your hair during this time. If you are a violent sleeper like I am (tossing and turning), it's OK to flat iron your hair straight again as needed. After 3 days, wash with a shampoo specifically designed for keratin treated hair. It MUST be sulfate and salt-free (more below). Maintenance: There isn't much to maintaining the treatment other than to use quality products. I use Keratin Complex Color Care Shampoo and Conditioner that I only buy from Ulta (3rd party sellers on Amazon are known to be knockoffs). Yes, it's expensive at $48 for a 32oz bottle...each. It hurts a little when I buy them. Actually, it hurts A LOT but it's worth it. I've been using them since my last treatment and without a doubt is the reason why it lasted so long. BUT, I picked up a set of Loreal Ever Pure Moisture Shampoo/Conditioner for camping and it's every bit as good and much more affordable ($17/23oz bottle). I don't get any kind of kick back from mentioning these two brands, just personal experience. Also, be kind to your treated hair. Keep it natural as much as possible, use sulfate/salt-free products (even dry shampoos, hair spray, etc.). Nothing will strip your hair faster than salt. Limit use of heat stylers. Other than doing this treatment I haven't used my flat irons in a year. When I have needed to blow dry my hair it takes much less time and I can use the low heat setting. Hopefully this review helps if you are looking for something to try at home.

I have bleached, greying, damaged hair and live on the Gulf Coast where the humidity can easily make 82 degrees feel like its 95 degrees out. This summer has been so hard on my hair, that Ive been living in a ballcap. I previously tried an at home nano treatment that did nothing but turn my beautifully toned hair an orange color. I saw this stuff on the Tok and decided it was worth a try. When I say I cannot believe how good my hair looks and feels, Im not even kidding! I spend mornings outdoors feeding horses and normally come home with a frizzy mess. But now? The humidity barely does anything to my hair. Its smooth and shiny and soft. Only downside is that the process does take a long time and when I say the product is strong?? Definitely keep a mask and gloves on. I have a tiny bathroom and had to keep sticking my head out for clean air. Despite this, I'd do it again in a heartbeat. Totally worth it. I just wish Id known about this stuff sooner!

I almost don’t want to recommend this because I’m afraid it’ll sell out and I won’t be able to repurchase it - but honestly, it’s too good not to share. This at-home hair straightening treatment is amazing. Fair warning, though: the fumes during the blow-drying stage are intense. Like other reviewers said, you really need to be careful. I covered my entire face with a mask because it was that strong. But the results? Absolutely worth it. Wow.
