KATIVABrazilian Straightening Kit, 12 Weeks of Home Use Professional Straightening, with Organic Argan Oil, Shea Butter, Keratin & Amino Acids, for Straighter, Softer and Shinier Hair, All Hair Types

I absolutely love this product! It made my hair incredibly smooth and sleek—just like a professional salon treatment. The results are noticeable and long-lasting. The only downside is that the process does take some time, whether at a salon or at home (and at home, you’re doing it all on your own). But honestly, the results are worth it! I’ll definitely be purchasing this again.

I was tired of spending $300 for this treatment at a salon when I knew I could do it myself, so I tried this product. It is amazing and worked perfectly!! But as others mentioned, it will strip color out of your hair so please be cautious of that!! I have to go get a toner done because of that. But my hair is straight and silky!

This stuff is awesome! I have curly/wavy/frizzy hair. I usually get a keratin treatment from my stylist. It cost $300 plus tip. I decided to give this a try, and so glad I did. The worst part is drying your hair with the cream on; it takes a very long time. It had a really strong smell when flat-ironing, so I put on a mask, which helped. I also used a cotton glove on the hand holding the hair when flat-ironing because your hair will be so hot. I made several passes with the flat-iron on each section of hair. I have washed and dried my hair several times, and it is still silky straight.

I tried this straightening treatment after struggling for years with frizz and excessive volume, and the truth is that I was pleasantly surprised. From the application, the difference was noticed: the hair was super soft, manageable and with a spectacular shine. The process took a couple of hours, but the result was totally worth it.The straightening left my hair completely straight without mistreating it or leaving it heavy. The best thing is that I did not have that strong smell typical of other similar products, and it did not cause burning or irritation on my scalp. After the first wash, the effect remained intact.

Safe, Formaldehyde-Free, and Truly Effective!I used the Kativa Keratin Kit formaldehyde-free, and I’m amazed by the results! My hair is smoother, shinier, and frizz-free — without any harsh chemicals. It straightened my hair naturally, while keeping it soft and full of life. I also love that it has a pleasant smell and doesn’t irritate the scalp like other treatments. If you’re looking for a safe at-home keratin treatment, this one is a game changer. My hair looks like I just stepped out of a salon

I helped my 14-year-old use this Straightening Kit, and WOW—the results were even better than our usual Keratin treatments! 😍✨Why We’re Obsessed:✔ Smoother, Shinier, Softer Hair – Her hair went from frizzy to silky-smooth, and the shine? Next level. It looks healthier, stronger, and way more manageable!✔ Lasts Longer Than Expected – We’re used to salon treatments that fade fast, but this held up beautifully, even after washing multiple times. 💁‍♀️✔ No Harsh Smell – Unlike some treatments that have you gasping for fresh air, this one was totally manageable! We had the bathroom fan on, but it wasn’t overwhelming. 🌬️✔ Easier Than We Thought – The instructions were straightforward, and while it took some time, it was so worth it. The final result looked like a professional salon job! This took a while to do only because my daughters hair is thick📸 We totally forgot to take before-and-after pics! But trust me—the difference was HUGE. She can now towel dry her hair and it's still straight! Not fuzzy!If you’re on the fence, just get it! It’s affordable, effective, and lasts longer than salon treatments. We’ll definitely be using this again!✅ 5/5 – Frizz-free, shiny, and totally worth it! ✨

I used this product a week ago and it does work for the most part. My hair is mostly straight after blow drying it, and for the first 5 days, my hair was super silky and smooth. On day 6, I noticed my hair was starting to get frizzy again. Also, this product will make your hair STINK!! I’m not just talking about stinky hair while the product is on—I applied this 7 days ago and my hair still smells. My husband barely wanted to sleep next to me because he said my hair smelled like old cheese. It smells worse when it’s wet.
