I am extremely impressed with the Kativa straightening treatment! It was very easy to use and the instructions were simple to follow. The results were even better than I expected — my hair came out smooth, shiny, and perfectly straight without feeling damaged. What I love the most is that my hair feels soft, frizz-free, and so much easier to manage. The effect lasts a long time, even in humid weather. It truly looks like a professional salon result! For the price, the quality is excellent. I will definitely buy it again and highly recommend it to anyone looking for a long-lasting, gentle, and effective straightening treatment. Read more

This Kativa Brazilian Straightening treatment works very well. From the first application, my hair was smoother, softer, and frizz-free. It doesn't have a strong odor and doesn't damage the hair. It's easy to apply at home. Excellent quality. Read more

My obsession with keratin began years ago when I was living in Korea and came across a keratin serum that transformed my hair, but this is the first time Ive done this kind of treatment. Decided to go for it so I could air dry my wavy hair without having to smooth out the kinks with heat every day - Id definitely say I achieved that with this product, and the added shine and silkiness this gave my hair is crazy. You REALLY want to make sure you take your time, blow dry the product completely (this does take some time!) and then straighten in small sections. The more time you give this process, the better your results will be. I did the minimum amount of passes the instructions said as I didn’t want stick straight. Love, love, love. Read more

Wow, I am so impressed with this keratin treatment. First, I did my research for about a month or two. This treatment had great reviews. I was also looking for a product for Afro hair. My hair is about a 4b. Yes, this treatment worked for my hair. The result were great!! I followed the directions carefully. I only used 410 degrees on my flat iron. The only thing I would do differently is wear a mask. I was in my bathroom with the door open and still needed a mask. I could feel the effect of the fumes in my throat when flat ironing. It did not ruin my curls.....It just soften them . Which I love. Read more

I have curly hair, and this keratin worked very well for me. It made my hair very soft, smooth, and much straighter. My hair looks shiny and feels healthy. One thing I really like is that it has no strong smell. I am allergic to regular keratin products, but this one did not cause any irritation or allergy at all. I highly recommend this product, especially for people with sensitive skin or allergies. It is a very good product and worth buying. Read more

I had the opportunity to try this product on my curly hair (3C curls, spirals, and waves). I was prepared to take the time that other reviewers mentioned would be needed to go through the entire process. It took me about 3.5 hours and I have hair that goes past my shoulders when curly and to my chest when straightened. The process is long and I followed it diligently which I think is key to getting the desired results. I even went through small sections of my hair with a straightener for a minimum of 8 passes. It was tedious and I was still skeptical about the results. And since you don't know how the hair will turn out after putting in all the time and effort it felt like a bit of a gamble. As the last step, I washed my hair and put conditioner on it and could immediately feel that the texture of my hair changed. Usually when wet, my hair still has curl - they're elongated but still there. After using the product, going through the process, my hair when wet was straight. I let it air dry because at this point I didn't have it in me to blow dry my hair after 3.5 hours. And WOW - it was slightly wavy but mostly straight - definitely would be easy to have blow dried my hair straight with the results that I got. I've had the Brazilian Blowout done professionally and the results with the DIY kit were nearly the same. I say "nearly" only because I could see the benefit of having someone else help with doing this as the back of the hair can be tough to make sure you've gotten enough product on it and you've properly passed through it with a straightener. I'm really happy with the results and when I air dry it looks like my hair has natural beach waves (which is what I remember when I got it professionally done). It takes a bit of time and effort, but is worth it if you want to avoid spending $$$ at the salon. As others have mentioned, when you straighten with the product there is smoke and a smell. I didn't notice the smell until I was closeer to my face, but saw the smoke during every pass. Do this in a well ventilated area. Read more

It did exactly what it was suppose to do. My hair is soft, frizz free and beautiful. YOU MUST FOLLOW THE STEPS. I’ve read other reviews that it didn’t work- people don’t follow the directions. It’s a long and tedious process. But huge con- it was NOT formaldehyde free like advertised. And I know this from doing several Brazilian keratin treatments. First- it burned any part of my skin it got on. Second it turned my dark brown hair orange. It literally bleached my hair. Third- I ordered the formaldehyde free because I have color in my hair…. And it wasn’t. Hopefully in two weeks I can tone it back to my original color. Read more
