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!

First: THIS WILL TAKE ANY COLOR HAIR DYE OUT OF YOUR HAIR . IF YOU HAVE COLORED HAIR, BUY THE COLOR SAFE ONE. My curl/wave pattern is a mixture of 2c wavy and 3A curly. My hair is also super dry and gets frizzy easy. If I am wearing MY HAIR straight I absolutely have to blow dry it and straighten it(and use tons of anti-frizz products. And on the days that it rains or it is humid outside my hair gets super frizzy and puffy. So living in Georgia where we have very humid summers typically during the summers I have to wear my hair pulled back, or curly with a good cast to keep it from getting puffy, bc no amount of frizz ease or moisturizing hair cream helps. I HAVE NEVER BEEN ABLE TO JUST WASH MY HAIR AND LET IT AIR DRY, OR ONLY WASH AND BLOW DRY. This product has SAVED me so much time. My hair feels healthier than it has ever felt It is so soft and shiny. And I can literally wash my hair brush it and go and when it dries it is still straight and not poofy/frizzy. So far it has been about 3 weeks and my hair is still amazing! For those who said it didn't work I fully believe they did not follow the instructions and do it properly. It is a long process but if you do it properly I promise you you will achieve the results that you want. The longest part of the process is blow drying your hair after you put the treatment in. After you put the treatment in let it sit on your hair for the amount of time that it tells you which is I think like 20 minutes. After that section your hair and use a very fine tooth comb and comb your hair in sections and get the excess treatment out with the comb. Every time you comb your hair you have to use a towel to get the excess off of the comb, You want to get as much excess out of your hair as you can before you start to blow dry it ,Don't worry if you don't think you've got out enough of the excess treatment, It's fine it will just take you a little longer to blow dry it in. You want to do this in a very well ventilated area, If you don't have big ventilated areas you can do it in you can do it in a small area however I would definitely suggest taking a fan and opening a window and having the fan set up to where it sucks all of the air from inside of the room that you're in and blows it out the window. The blow drying step would be better if you had someone to help you only because depending on how thick or long your hair is it can take a while. It took me about 2 hours to get it dry (no breaks) because it has to be completely dry before you start the straightening phase. I really think people are not letting get all the way dry before they straighten it and that's probably why it's not working as well. So if you have another person that can help you I would suggest it My husband ended up coming again helping me so my arms could take a break. Also do not put anything else in your hair Do not try to put no heat protectant in or any additional conditioners. Once your hair is completely dry that's when you're going to straighten it. I put my flat iron on 450 (typically I only have it at 350 whenever I flat iron my hair) Now, This is an important step because if you do not straighten your hair properly, the treatment may not work as good. Instead of flat ironing my hair the way I normally would which is just three or four sections I actually sectioned it off to smaller sections that way I could really focus on each section. Also you're not going to hold your straightener on each section like some people do when they're straightening their hair and they hold it for a few seconds before they move it down, your going to do medium passes (not fast passes but not too slow bc if you go really slow you risk heat damage) but you're going flat iron each section, with about 10 passes so make sure you really get that treatment to work. My hair is medium thickness. The front of my hair comes down about an inch below my collarbone and the back of my hair comes down to about 2 in above my bra. I used to dye my hair a lot and I would need three boxes of dye. The amount of product that comes with one box of this treatment was plenty and I still had some left over. If you have some stubborn areas of your hair, Where you feel like the treatment didn't work as good You can always use the treatment you have left over and only put it on that one area blow dry it and Let it sit for 20 minutes and flat iron it. Instead of doing your entire head again. (It has a 6 month shelf life after open). However, If you do have long hair I would suggest buying two just to make sure you have plenty. I have fallen in love with this product so much that I have been telling everyone about it! I was not paid for my review I bought this product with my own money after doing research myself on something that will help with my poofiness and my frizz.

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.

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.

Umm WOW. I typically have curly, frizzy hair and straighten my hair about once a week. Well, I broke my hand and am getting surgery tomorrow, so I thought I would try using this to make my hair more manageable while I am in a cast. Spoiler alert: IT WORKS. Not only reducing frizz, but straightening. I’ve had many Brazilian blowouts done professionally and liked the results, but never got stick straight hair from it. This stuff- after washing it out and blow drying it, it’s perfectly straight and no frizz whatsoever, but still has volume! As I was doing it, I was thinking to myself gosh this is such a pain, I’d rather pay someone to do this. After seeing the results, umm nope this will now be my new job. A couple tips: double shampoo, before putting on product, be meticulous with the drying and straightening. Your hair will have a nasty texture to it- it doesn’t look dry but it is. Do everything in a very well ventilated space! The fumes are strong. After straightening, double cleanse again, then use k18, then a conditioning mask. Finally, blow dry and enjoy!

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.

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.
