Complex Brazilian Keratin Hair Blowout Treatment Formaldehyde Free with Inverto 120ml with Clarifying Shampoo Straighten Repair and Smooth Hair by Keratin Research Keratina Brasilera

I did a lot of research on the best kind of keratin treatment to do at home and this was the best one I had found after concluding a long research and watching hundreds of videos between tik tok and YouTube. I did get discouraged when I read the reviews here and saw that even a professional did not know what she was doing or how to use the product. I have type 4 hair curly hair and I am African American. I’ve struggled for the longest with frizz, breaking and strengthening my high porosity hair. With high porosity hair, you have to feed your strands more protein than others, you need to moisturize more often than others and you may even find more split ends than others. As I was reading the importance on keratin and what it can do for hair, I realized the problem people are having when they try keratin is that half the time they may not be eligible or a good fit for the treatment. If you are sensitive to protein or you have no issues with breakage/hair fallout, this is NOT a treatment you should do as it WILL harm your hair. For someone like me, with high porosity hair I fit the requirements based on the BENEFITS! It took me maybe 4-5 hours in total to complete the process. I used the entire bottle, barely was enough but I’ll grab 2 next time. The instructions are pretty straight forward and I did everything minus the 3-day usage of flat ironing, I only did a follow up one day and washed my hair after 5 days with a moisturizing shampoo. When I say my hair has never been so fluffy and light and shiny!! My split ends have all just about disappeared; I even went ahead and trimmed my ends anyway but when I examined what was chop, not a single hair had splits.. wash days now take 1.5 hours to finish up (including deep condition and style), I barely use product now? My hair has zero frizz while still having a little bit of texture at the same time. This product does exactly what it says it will do… FOR THE RIGHT CANDIDATE! If you are looking for a STRAIGHTENING treatment, they have a stronger version.. this particular keratin treatment is only for strength, manageability and frizz control. That’s all I was looking for with my treatment as well as the form free and it’s perfect! I’m a keratin baddie for life now! Lol

I was very close to “chopping it all off,” but my husband likes my mid-back length hair and asked me to try this one last thing. My issue was that over the last few years about two inches of my hair all along the nape of my neck had gone from being wavy (like the rest of my hair) to being kinky curly with a tendency to frizz. It was so much curlier than the rest of my hair that it made that part of my hair hang inches shorter than the rest of my hair. I had looked into salon keratin treatments and had decided it just wasn’t worth the cost...hence, I was ready to try a pixie cut. I have now used this product three different times. My hair stays manageable and shiny for at least three months. In fact, this last time I didn’t feel most of my hair needed the treatment (just the hair toward the nape of my neck that starts to curl and frizz sooner than the rest of my hair, but even it will last at least a few months). My husband loves that I’m happier with it and am wearing it down. There are two negatives: one, of course, is the terrible smell during the flat-ironing portion (we open a window and turn on a fan for that part), but other than that the effort is well worth the long-lasting manageability. The second negative is that it did change the color of my hair somewhat. I have naturally medium brown hair and my hair has more of a reddish tone after treatment. I could see this issue being a deal breaker for some, but I didn’t find it to be a big issue. I know these issues could lead others to rate this far less than five stars, but I am giving it five stars because it has consistently made me love the way my hair looks with almost no daily effort.

So I have had tried this as well as professional keratin treatments twice. This product was effective. My hair now air dries very fast, it is completely straight and shiny. THE DOWNSIDES: -Third wash and my hair still stinks like chemicals when wet. But smell goes away when it dries. -It changes my hair color. I started with black hair and now it is brown/ red. But it has done this with professional treatments also. - My hair is definitely more dry after the treatment. When I had it professionally done my hair felt healthier. At least it is very straight so it helps prevent knots. UPDATE: DO NOT BUY. THIS STUFF HAS RUINED MY HAIR AND THE SMOOTHING EFFECTS BARELY LASTED. MULTIPLE HAIRCUTS LATER AND MY HAIR IS STILL TRASHED

Let me start out by saying I hardly ever leave Amazon reviews and bought this with my own money, but I felt I needed to review this one. A little background on my hair story. I am 25 and have always had long hair. And since puberty, hormonal changes, stress and not the best diet, my hair has been frizzy poofy for probably the last 15 years. However, I have always tried to take care of my hair, I rarely use heat or styling tools. I just wear it as is. That is why I really can't understand why my hair looks so bad. I have tried Vo5, olive oil, coconut oil and every other kind of drugstore hair moisturizing products, with not much luck. Vo5 has probably been the best. I have struggled with tangled, frizzy, poofy, dull looking hair no matter what I do for so long! My hair also will not stay straight, even when I rarely do try to straighten it! Going through all of this through my teens and young adult years has been so discouraging and frustrating. Doesn't make me feel put together, when my hair always looks like a mess, even right after combing it! I have been debating doing a keratin treatment for probably 5 years, I am always afraid to do anything drastic to my hair, because like I said, I rarely even use heat on it! But, I finally got up the nerve to do this treatment and all I can say is WOW! I wished I had done this a long time ago! My hair is so soft and manageable! For the first time, in I don't know how long, I can run my fingers through my hair from the roots to the tips!! My ends don't look dry and crusty anymore. I just trimmed my hair, as well as going through it and thinning out dead hair with thinning shears probably two weeks before doing this treatment, but even with trims, my ends always looks dry and dull. But, now my head of hair all over finally feels like it is holding moisture and conditioner, and is finally shiny, and not poofy or messy! The only con I have, my hair did not turn out as straight as I would have liked. It still has a lot of my natural wave in it. But, in a way, I am glad I retained my natural texture. Also, first time straightening my hair after doing treatment, it is still not straightening pin straight. HOWEVER, I only have one of those simply straight, as seen on tv, straightening heated brushes. SO, maybe that brush is just not enough to straighten my hair. Like I said above, I rarely put heat on my hair, I decided on a whim a few years ago to try one of the simply straight brushes, as it seemed less scary than putting a flat iron on my hair. I didn't want to spend money on buying a flat iron for this treatment, just to set the product in, as I figured I would not use a flat iron that much. Maybe if I had used a real flat iron to set the product in, maybe my hair would have turned out straighter, or maybe it's just how my hair reacted to the treatment? Maybe I need to do multiple treatments before my hair will get straighter? Pros My hair is far less frizzy and poofy. And is much softer and more manageable. I can run my fingers through my hair again!!! Also seems like my hair is far more resistant to humidity, as I did the treatment at the end of June, on a hot day! Con First impression after doing the treatment and my hair dried, my hair still retained a lot of its natural waviness. Doesn't seem like this treatment straightened my hair much. Also, even with using a straightener, still did not make it pin straight. However, like I said above, maybe its because I am using the simply straight heated brush and not a real flat iron. And also, maybe it is just due to the condition of my hair, as to why it didn't turn out straighter. I am giving it a 4 star, because my hair did not straighten much. However, like I said above, it may not be the products fault, maybe it is just due to the prior condition of my hair or because I did not use a real flat iron. Overall, I am happy with the results so far. It is life changing for me, to finally get rid of the annoying, unconfortable frizzy, poofy mess that was my hair before this treatment!! I will try and update after more time passes, and post how long the keratin treatment lasts for me.

First off, this product is super easy to use! I have thin shoulder length hair that I was able to get two uses out of this product. Mind you, you might have Better and lasting results if you went to a salon and spent $300. But this works for two months or less, specially when you are about to go on vacation where humidity is high. I live in Florida and my hair lasted well for about a month. I would wake up wash my hair and it would legit take 10 mins to blow dry. It was soft and shiny and my co-workers noticed the first day! Normally I go to work with my hair knotted and tangle because I’m to tired to deal with my hair anymore, depressed about my hair. But buying this and giving this a try. Was totally worth it. It gave my hair confidence back instead of spending hundreds of dollars on products that don’t work on my hair for more then a few hours. This is definitely worth it for me. People had concerns about breakage. I had a little hair lost when putting on the product, mind you they have you blow dry ur hair without any protectant and flat iron it, it will make some hair loss but nothing noticeable. Easy to do on a boring weekend. You’ll be happy you did it. I wash and go sometimes to have a slight curl and sometimes I flat iron or blow dry to keep it straight. I bought this in Nov and I’m reapplying it at the end of January, now that I notice my hair is starting to be a hot mess again. I ordered this again In March and Now in July :)

I waited a few months before reviewing this to see if it would last and I am happy to say I loved the results and am still satisfied. It was difficult to use as the hair gets very sticky when you are trying to blowdry and flat iron it, so it's a lot harder to use than other types of quick keratin I've done (Coppola last time) to myself where you end up rinsing out the product before straightening, but the results on this were much better. It did take me about 3.5 hours from start to finish though, because there are multiple phases to this, including just letting the product sit. I'm not a professional but I do color my own hair and I use a 3 way mirror so that I can see the sides and back and feel pretty comfortable using products on myself. If you don't have the time or ability to really be thorough then maybe skip this product as it is very labor intensive but if you are willing to put in the time you should have great results. It was hard at times for me to figure out which sections of hair I had already gone over with the straightener and which I hadn't, since it's not the silky texture you're picturing as the end result, when you're actually going through it. If your hair is very thick like mine, then when you're in the midst of it you might think you made a wrong choice but when I was done, I loved how especially the baby hairs close to my scalp that are usually curly were straightened. Hairs at the back of my neck that usually get frizzy still are pretty straight 3 months later. The results are fading only because of new hair growth and not because I think the keratin on the existing hair is wearing off.

I wanted this formaldehyde free formula to work but it didn’t work near as good as the formaldehyde formula that you leave on for a few days. I did take a lot of my frizz out and seemed to be mostly straight except a few areas in the front when I washed the product out but when I washed again A few days later with my sulfate Free shampoo I saw a lot of wavy areas that weren’t there at first. I also made a point to take my time going over an area I had in the front by my face with the product and flat iron and it seemed like it didn’t take in that area. For the money I’m not that happy. I guess I need to go back to using the other formula. Maybe i should have left it on longer but it said you could wash it same day. Maybe I’ll try and go over those areas again that didn’t take. I also need to mention that I kept it out of bands and clips and flat ironed it like the instructions said too.

First, my hair is very thin fine dark blonde with light blonde highlights. It is fairly long and hits my mid back. I have a little curl but mostly wavy with a ton of breakage and frizz. I have no experience with coloring my hair or doing this process by myself. I have always had a professional give me highlights or do Brazilian blowouts. However since money is tight I decided to take chance and do this myself. It turned out awesome! No more frizz! It was time consuming. 3 1/2 hours including the 1hr processing time. I found the instructions very easy to follow and watched a few videos for tips. The product had very little smell and was easy to apply. I applied using a brush a stylist uses during coloring applications. I tried not to put on too much product and evenly distributed it by using a fine tooth comb. I also used both a flat iron and a curling brush to make sure it was baked on well. It did seem a bit sticky until you wash it the final time and I used the deep conditioner. But after washing it, my hair was soft and silky. Just like I had it done in the salon! I have a ton of product left so I think I could do this at least one more time. I was worried it might effect my color or highlights but it did not. I was sure to follow the directions of using a lower temperature on my flat irons to prevent discoloration. I am really glad I found this product. Now I hope it lasts! If not, I will update this post.
