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

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.

The product arrived 2 days after ordered. I got an email from the seller with explanations how to do the treatment correctly, with links to more information and a phone number of Haim K (I assume the CEO of Keratin Research), and indeed I called him because I had a few questions. Haim answered immediately and was so patient and took his time to give me all the information I needed to do the treatment at home. The package comes with detailed instructions too, they really do all they can so you have all the information to succeed just like a professional. I did the treatment on my daughter who had bleached damaged hair, and a few days later to myself. The process take about 4 hours if you follow the instructions, but well worth the results. The fumes did not even bother me, no eye stinging, unlike other keratin treatments that contain formaldehyde that make you feel sick. After the final mask (great mask, bought more after the treatment for further use) the hair was 100% frizz free straight and shiny. The only thing you need to pay attention is that bleached hair might change it's color toward the yellow hues if you use high temperatures with the flat iron. I corrected it with purple shampoo, but Haim said they are working on a product that is intended for blonds that already has the correcting toner in it. I don't know how long this treatment will last but having it at home is great, I might even be tempted to do a few touchups if it just starts wearing off. I totally recommend this formaldehyde free kit, and having such great customer service and someone to talk to if I need help is worth a lot too.

I'm a professional cosmetologist licensed in New York and France... I have used different keratin treatments which claimed to not have formaldehyde and other harmful chemicals but turned out to be in recall, sold without an autorization from the US and actually completely banned from the market later on as it was found to be harmful after all... Ridiculous, greedy market! You can search and find for a whole list of those on the internet if you are curious about it... Inverto is not on those lists. I've used a natural anti-frizz keratin treatment which was based with plants and vegetables, it was great to control frizz but would leave the hair dry if not using the same products of the line as a maintenance at home... These products were expensive... With the Inverto, you control frizz, give a lustrous shine that lasts, the maintenance products aren't pricy. I get clients who get frizz free from 4 months to 9 months depending on the quality of the water they have at home, the shampoos frequencies, especially the kind of shampoos they use, their lifestyle, the level of frizz they had to begin with, the level of damage their hair had and the texture of their hair. This is a treatment you'd use on people with straight hair with frizz, wavy to curly if you want to get good results but not for the kinky curly kind of hair. The clients with straight and frizzy hair (frizz caused by health issues/medications or chemical damage and so breakage and high dehydration) get shine back, no frizz, life back to the hair, and smoothness. Though keep in mind that the treatment needs to be fused to the hair by the way of a flat iron and so high temperatures. This means that sometimes a keratin treatment won't be what will help you right now if your hair is overly damaged. I'd advise to begin with replenishing treatments before considering a keratin treatment... The wavy hair clients get all the results as the straight hair ones do but sometimes get their waves losen down to straight hair depending on the strength of their waves. About the same results with the curly hair ones. The results on the curls depends on the strength they have but also they can get wavy to looser curls as well and so get diminished volume. 👍👍 This is a treatment I'd recommend to get rid of the frizz or tame it down and bring back your hair to a healthier look with shine as well. It is not a keratin treatment to get your hair straight. I hope my review helps understanding what this Inverto treatment does. 😇 The directions are simple and need to be followed with care. It comes with a great and efficient clarifying shampoo and a wonderful mask. I usually get out of this tube 3 treatments for medium length and medium thickness hair, 4 if it's for a thinner and shorter length hair client. 😎 I like the fact there's no need to oversaturate the hair with this treatment. Please make sure you follow the advise of an educated cosmetologist aka a board certified professional or even a cosmetologist trained by a board certified professional and have it professionally done. 😉
