KATIVA Brazilian Keratin Treatment Kit at home Formaldehyde Free Hair Straightening with Hyaluronic Acid, Up to 12 Weeks Frizz Control for Curly, Wavy, Frizzy Hair (Straightening Kit)

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.

I am fascinated by this product. I have never used it before today. I see a friend of mine this week and her hair looked amazing - stick straight and shiny and healthy. I asked her what she was using and she said she had just done this treatment. She sent me the link and I ordered it. I’ve never done anything similar to this at home or at the salon before. I do color my own hair at home but that’s it. The package came and there are several steps. It takes a lot of time and patience. When I was done and got in the shower to rinse the cream out I can tell you that I noticed my hair felt thinner. I have naturally very thick hair but it felt less heavy. Then I washed my hair with the shampoo and conditioner provided. The only negative thing I will say about this product is that there is not enough conditioner provided. I barely had enough and if there had been more then I would have used it. After I got out of the shower I did not put any product in my hair and I blow dried it. It looks exactly how it looks when I get a blow out at the salon. Again, no product and no flat iron yet, just a simple blow dry. I am amazed. My hair is usually very frizzy and I wouldn’t even bother to blow dry my hair without using a de-frizz product but somehow this product and the process has cut the frizz. I live in a very humid environment and it’s still hot and humid here and still, no frizz. I haven’t even flat ironed it yet! I am so thoroughly impressed and I highly recommend this. I hope it will last for several weeks and I will try to remember to update this review but so far, I am really pleased. The price is half the cost of a salon blowout. Yes, it takes awhile, but if it lasts several washes then it will be very worth it. My friend said hers had already lasted a week and trips to the gym and washes. I’m super excited to have found this.

This stuff is amazing- but there aren’t detailed instructions on the box. Thankfully, I watched some YouTube videos before I used it and I got beautiful results with shiny healthy hair and zero damage. My hair is now silky straight (and STAYS bone straight until washed) from just blow drying and, when just washed, my curls are looser. Some tips before you begin: 1. Do the hot ironing outdoors or by a window, in a well-ventilated area and wear a mask. The fumes are STRONG! I opened my window and had the hot irons sat on the window ledge in between use so that the fumes went outside and I stepped back. I also held my breath while I passed the hot iron through my hair. 2. Wear gloves whenever you are touching the product. The gloves on the box are flimsy- you might want to get some better gloves. 3. Set aside up to 2 hours for this process. It’s easy but tedious and time consuming. 4. The solution lightens your hair a bit, so if you want to color your hair do it afterwards. I used a box dye the next day and my hair was just fine. Step 1. Wash your hair with the shampoo- repeat and blow dry Step 2. Apply the straightening cream. Let it sit for 15 minutes- I started counting the 15 minutes from when I finished the application. And then comb out any excess cream with a comb. 1 pack was enough for my hair. It might itch or sting a bit but this will subside once you start drying the hair. Step 3. Blow dry the hair in small sections. I used a hairdryer with a brush attachment which made it easier. Step 4. Flat iron- I set my irons to 380f and passed my hair through 6 times. You can pass your hair a few more times if you want. 6 times was good for me. I used a fine tooth comb to follow through after the irons. The fumes and steam will make you think you are frying your hair- but trust the process. Work in small sections to ensure you are getting every strand of hair. Step 5. Shampoo your hair thoroughly and apply the conditioner. Finish by blow drying. I was tired after all that, so I let mine air dry. I then colored my hair the following day and blow dried it afterwards.

I'm so sad I didn't get a before/after picture because BABES this stuff is for real!! Long story short I've been fighting frizzy, damaged hair and couldn't afford the salon treatment above my already expensive color-treated hair so I gave this a shot after seeing some of the great reviews and guys, THEY DO NOT LIE!! Let's start with the cons (there are a few, but well worth bearing through): -This process is time consuming if done right, and requires following the included directions closely - avoid using the ones found on the side of the box as there is more to it. The whole process took me about 2 hours to complete. I have coarse, mixed curly + wavy + frizzy, long, but thin hair and didn't even use all of the activator to fully cover my strands. (That last part was more of a pro for me!) -It is messy and smelly when blow drying!! I expected the mess (similar to dying my hair at home, but creme is a bit thicker) however the smell was strong in my tiny bathroom so I kept fans on and gave myself breathing breaks when needed. -Definitely avoid the activator touching your skin because it did burn. A bit more so than when I dye my hair and I get itchy. This stuff was no joke on the skin so keep it clean. I suggest a towel on the back of your neck. -Having to blowdry my hair with this stuff on was craaazy. I thought I would never get it dry enough to use the straightener but trust that you will because heat is crucial for this to work to its best so take the time. I believe this will also help it last longer too, so totally worth it. The Pro's: -I'm soo glad I took the time to use heat on my hair as much as possible (with blow drying + straightening multiple times over) because I feel that was the key to getting this awesome miracle to kick in. When I mean straightening, I mean going over strands more times than I normally would and at a higher temp. -After the final hair wash, I used only a blow dryer and HOLY COW - it straightened so much faster and with 90% less frizz (if not more?!) than normal. I debated letting it air dry but heard that it helps to continue to use heat on your hair a few days after. It truly is a night and day difference but am super curious to see how well this works once I discontinue blow drying. -My hair feels super soft and there is a shine and slickness to is that would usually take me more time to acquire. My god have I mentioned how amazing this made my hair look??? I can't stop touching it! So to close out this review, If you are tempted to get this, DO IT and DO IT RIGHT!! You won't be sorry and have that much more money in your wallet. I'm certain I will be buying more of this stuff in the future.

Good product for straightening hair at home. It significantly reduces frizz and leaves hair more manageable and shiny. I liked that it’s formaldehyde-free and doesn’t damage the hair a much. The application takes time and the effect doesn’t last exactly as promised, but overall it does the job and is worth it.

Ok. I admit it. This stuff is amazing! I have very thick, coarse hair that is about chin length. No matter what conditioning or treatment products I use, my hair will “balloon” out. For years I used a regular relaxer about 3-4 times a year. It worked, but left my hair pretty flat for a week or so, and the chemicals were really hard on my hair. Came across this as I was getting ready to order the regular stuff again. After looking at all the reviews, I decided to try it. The application process is time consuming -as other reviewers have noted, do allow any large block of your time to do this. If you have never had one of these treatments in a salon or done it at home before, it will seem really strange. Read several reviews with tips for doing this- Imfound them very helpful. There are limited directions on the box so I recommend scanning the code in the box and getting the more complete directions from their site on line. Read, reread, and read the directions several times and make sure you are comfortable that you understand the process before starting the application. Anytime the instructions tell you to completely dry your hair, be sure you do COMPLETELY dry your hair! Also, if you color your hair, note that it will remove some of your color. I use a brush hair dryer instead of a conventional type and wondered if that would work- it worked just fine. One other tip: as others have noted, it can be hard to do the back of your head. I did my treatment a few days before I had an appointment for a haircut, so the little ends in the back that I missed were just cut off! Since using this treatment, I do not need a lot of leave-in conditioning and moisturizing products any more. The heat from your hair dryer and flat iron will sort of “reactivate” the treatment when you style your hair after shampooing and regular conditioning. I am amazed- my hair is de puffed”, straighter, soft, silky, and shiny. I am not sure it is going to last the promised 12 weeks due to the thickness and texture of my hair, but I am also not worried about damage to my hair with repeated use.

As you can see in the photos, my hair was extremely damaged and very frizzy. I had tried many anti-frizz products before, but nothing actually worked or lasted. After using this at-home keratin kit, all of the frizz completely disappeared and my hair looks noticeably healthier and smoother. I can now wear my hair down and go out without worrying about it getting puffy or frizzy — even in Florida’s very humid weather. I’ve included photos taken immediately after the treatment, after several washes, and again two months later. Even after two months, my hair still looks healthy and smooth, and I am truly satisfied with the results. I also colored my hair about one month after doing the keratin treatment, and it did not remove or damage the keratin at all, as you can see in the two-month photos. The application process took me about 5–6 hours, which was a bit tiring, but the results were absolutely worth it. I would definitely recommend this product to anyone struggling with frizz and damaged hair.

The pictures speak for themselves. I blew dry my hair with the same heat / settings and brushes in both before and after. Look at the difference! I never write reviews, this product works. Please note. The fumes are fumey - you need ventilation. It’s no joke. Also the process of drying the product in your hair is gnarly and time consuming. And also sticky and not pleasant. My hair lightened a bit but nothing crazy. Also!!!! I have seb dermatitis and it was mildly irritating in some spots but no crazy hair shedding or anything noticeable. I avoided my root as much as possible. The entire process end to end took me 90 mins. Worth it!
