hair treatment! I’m really happy with this KATIVA treatment kit. The instructions were easy to follow, and while the process takes a little time, the results are definitely worth it. My hair felt much softer, shinier, and easier to manage after the first use. The biggest difference I noticed was how much it reduced frizz and made my hair look smoother without feeling heavy or greasy. Styling my hair is now much easier, and I don’t need to use as much heat to get a sleek look. I recommend following the instructions carefully for the best results. If you’re looking for an affordable at-home treatment that leaves your hair smooth, healthy-looking, and manageable, I highly recommend this product. I would definitely buy it again!

After years of having to cut inches off my hair every winter from the damage braids were doing to my hair every summer, I decided no braids this summer. I also didn’t want to go back to the salon as I’m still recovering from a botched haircut. Needless to say, as a 4c girl, I’ve been fighting for my life. I was about to make a braid appointment, until I saw a straight natural’s video about her keratin treatment & next thing you know this is at my doorstep. I read the full directions from the qr code, watched a couple of videos & got started. I took my time & followed the directions to the letter. I’m not going to lie. When I started blow drying my hair with the treatment in, I got scared. My hair felt stiff & tacky, and I couldn’t quite tell if it was actually dry. If you’ve ever had protein overload, it kinda felt like that and I was shaking in my boots. It was time to put the flat iron on this mess and it felt like I was abandoning every basic hair care principle I know. I looked in the mirror, convinced myself my face is pretty enough for me to be bald, and I started flat ironing, prepared for my hair to melt off. After doing two of the tiniest sections, I saw my hair remained attached to my head and I finished the treatment. My hair felt better but still a little stiff. I was tired at this point, but I didn’t want my hair to over process, so I told myself I’d do the the final wash & condition and just go for a quick blow dry, and I’d style it in the morning. Imagine my surprise when it took 5 minutes to blow dry my hair and when looked in the mirror, my hair was already done. Shiny, healthy, and the best it’s looked in years. The only thing I did to my hair in the morning is throw some heated rollers in for 10 minutes. When I do this again in a the fall, I’ll probably turn down the heat on the flat iron during the treatment because I wouldn’t mind a bit more volume and it will be easier to manage when it’s not so humid. And that’s the best part to me. Doing this one time already shows me how I can make adjustments to get exactly the results I’m looking for. The only regret I have is not doing this years ago. I could have saved myself thousands of dollars, hours of time, and so much frustration from these hair stylists making me read their 30 pages of rules & charging $300 for a blow out.

I have very curly frizzy hair. Even when I straighten my hair it will frizz and curl right back up in a few hours. I completed the treatment almost a month ago and it still looks amazing. I usually wash my hair once a week and this is what my hair looks on day 6 of not washing it, no heat (other then the initial blow dry), no styling product or anything. This is just how my hair is now and it's amazing, soft, sleek and not frizzy at all. It does take a long time to do and it's important you're extremely through with it, about 4 hours for long or thick hair. I also recommend having one more box on hand then you think you will need. I thought 1 box would be enough and 2 boxes ended up BARELY being enough. If you do this treatment just know you can't do deep conditioning treatments, hair masks or anything like that anymore because it will weigh your hair down and make it look/feel greasy until you shampoo it again. It's supposed to last 4 months and for $38 I feel it's worth it, especially since the salon costs closer to $350 (plus tip & tax) and their products contain formaldehyde while this box does not. I personally never see myself going back to my natural hair and just completing this treatment every 4 months or so. It used to take me an hour a day just to make my hair look half decent. Now I just wake up, brush it for 20 seconds as it's so silky it's rarely tangled and that's it.

Dude it works! I’m trying to avoid another relaxer but my hair is coarse and I needed some help! I’m not sure a relaxer has ever gotten it this silky! 👏🏾 It took me about an hour and a half for the whole process. Which I thought wasn’t bad! The treatment felt almost like it was burning my scalp while wet but didn’t feel that way dry or after I washed it out(nothing close to what a relaxer burn feels like). I had to turn on a vent and fan while flat ironing. The smell was heavy! But worth it for the result. I still have a lot left for another treatment. Maybe two more. So well worth the money and was easy to do at home.

Overall very happy with results of this, but it's not without its pain points. I have used this kit twice now. It gradually loses its luster but it was probably about the 3 month mark when I felt like it was time to redo it. It's not as good as the formaldehyde formula keratin treatments of the past, but of course that chemical needed to go. Application is easy but the comb through step is pretty much impossible. I did this with a very wide toothed comb and it was still a struggle. It would never work with a standard comb. Blow drying the cream into the hair takes a long time and feels quite daunting. Some spots never do feel totally dry. After it has been washed out, the hair smells pretty funky....literally kind of like something dead, but only when wet, for a few weeks. It smells fine when dry. As far as results, they are great but this will depend on your goals. I have long, fine, curly hair. It is squirrely and my natural curl pattern is inconsistent in different areas and just never looks nice when I try to wear my natural curls. I've tried EVERYTHING to love my curls and ultimately just never have. As a result, I have been straightening my hair daily since middle school (I'm 41 now!). I have to blow dry, which anyone with curly hair knows results in a large poof ball on your head. Then, I would flat iron to get a smooth, straight look...every. single. day. I was so tired of having to use two tools every day to get my hair presentable, and then also having to pray it didn't get wet, or the air wasn't humid, etc. This treatment has loosened my curl to a beachy, fun wave texture. I can let it air dry and it has NO frizz and just the waves. If I don't want to air dry, I can literally just blow dry it without even using a brush and just raking my fingers through, and it dries straight and fluffy but not frizzy. I can use a round blow dryer brush if I want a more polished look, but in no circumstance do I need to flat iron. It's like a dream come true for my inner fuzzy haired middle school girl. It's amazing to be able to go swimming or just walk into the store in a light rain without having to worry about what my hair will do afterwards. I reapplied when I started noticing more frizz, and the curls starting to tighten back up (around 3 months). Because I am putting WAY less heat on my hair, it has been growing like crazy since it's not breaking off so much. My hair stylist, family members, and people at work have all commented about how long my hair is getting. I have not been able to grow it this long for many years.

I bought this because I wanted to control my frizz at home without spending a lot at a salon. First impression: The kit includes the treatment and a shampoo and conditioner, and the instructions are easy to follow(I also searched for a YouTube video to make sure I understood right). After using it I notice: ✅ my hair looked smoother and less frizzy right away ✅ It made my hair easier to style and manage ✅ My hair had more shine and felt softer ✅It last 6 months What I liked: -Good results for the price - Works well for wavy frizzy hair What I didn't liked: - The process takes some time to do properly - need to be in a ventilated area because the room is going to have a lot of smoke -since you need to dry the hair with the product on use a hair brush you don't mind getting messy (I got a cheap brush just for that). Who is this good for: 👉 Anyone with frizzy or wavy hair who wants a more straight, smooth look at home Final Verdict: I would recommend this because it gives noticeable results without paying salon prices. It takes time to apply but for the price it's definitely worth trying. I would use it again.

I genuinely did not expect this product to work but it did! Pictures are my hair: blow drying before using the product and after using the product. I live in a state where we see 94% humidity almost every day in the summer and my hair did not get frizzy stepping out into the humidity either! I recommend but also ONLY if you’re willing to put the work in, it’s not an easy process and is very time consuming (took me 3-4 hours and probably should have done longer but got tired of messing with it lol) it did not straighten my hair which I didn’t really wsnt personally but helped tremendously with frizz control

EDIT: I had leftover treatment and decided to just do a second round. I found the second time a little easier and slightly less time consuming (only slightly), and ended up with a looser curl pattern like I had wanted. Still not sure if the time invested is worth the output (2 treatments with 2+ hours of work each), but I was trying to avoid permanently altering my hair structure, so maybe that's the payoff. Depending on how and if/when this fades from my hair will determine if I think it's worth the effort, I suppose. But for now the results aren't bad. (original) I will preface this by saying i started half-assing this about halfway through. I was careful about not adding too much product and combing out the excess, but during the drying process it just *would not* dry. My hair remained sticky even after 30+ minutes of blow drying on high power. This was also why I was unable to do smaller sections with the flat iron. The end result is my curls looking more defined and juicy on most parts of my hair, but not the looser pattern I was hoping for. I can't complain too much, but it would have been nice to have more detailed instructions rather than the most basic of steps just on the side of the box (not even a peice of paper inside--what if the box had been damaged?). Also, the fumes are pretty potent. I had the window open and a fan blowing everything away from me and still had a few light coughing fits. All in all, I think I'd rather just do a relaxer or texturizer, as they're cheaper and easier, but will now have to wait for these chemicals to fade.
