Inverto Instant Weekly Keratin Treatment Replenisher Nourishing Complex of Argan Oil and Amino Acids Collagen Smooth Soft Frizz Free Shiny Hair with Thermal Protector

Having dry skin and scalp, it is hard to find a product that doesn't cause me some kind of issues. This has driven me to try all kinds of products, but this product works just right. Just comb it through your hair and it instantly handles better, makes it soft without accumulating on your hair and scalp. A bottle of this lasts me a good while longer than other things. The price is higher than some other products, but the quality of this makes it a great value.

I'm very pleased with this . I now use it instead of a smoothing serum I had . I have very thick, extremely coarse hair. While my hair is still wet I put this on, then blow dry. It make my hair shiny. Sometimes I'll put this in while my hair is still wet and let it air dry. It does make it less frizzy than if I'd let it air dry without product . Keratin Research brand products are great . And this is a good value !

Didn't recommendIt dries my hair every time I use it & causes a breakage & I'm sure now it doesn't include any natural ingredientsNothing but chemicals

This is a great addition to my keratin products. I use it to maximize my blowout and it works awesome! It takes less than 5 minutes and my hair looks good. I mostly use it when my hair is damp before I dry it, but I have used it later in the day on dry hair and it brought my look right back! I have switched from my old products and now just use this one. This increases the time between the blow out treatments that I do. I highly recommend this to everyone!

I’m a bit of a haircare junky. I have done multiple keratin treatments over the years. I decided to try this as an alternative to using a full blown keratin treatment. I expected more mild results and I guess that’s exactly what I got. The formula feels a bit sticky on the hair. I think I will use a very small amount of this as an additive to conditioning or as a leave in after washing. After doing the whole blow dry and flat iron process with a 450 deg temp I did expect a bit more. I have already ordered some full strength Keratin called QOD Gold that has great reviews so I plan to stay away from mild treatments such as this one going forward. If you take all the time to seal it on your hair the results might as well be stronger. Just my opinion. For reference I have fine, porous 3b/3c hair.

Just the keratin treatment booster I needed. This is my first time trying the Inverto products and they work perfect for my hair. I have thick hair with big curls, and it works great. This product is worth the money! I have thick dark hair with natural big curls. I also did the Inverto keratin...amazing! Amazing product line!

I have a keratin treatment in my hair. I use a very small amount on just washed hair. I have let it air dry and it turns out very nice without frizz. I have also used it and blew dry by hair. My hair seems to dry very fast. It is heat activated but still works when air drying. Some times it is just to hot to use a blow dryer. I would buy this again.

After 1 month from my diy keratin treatment, I bought this. By that time, I could see my hair start curling slightly and slight frizzyness coming out. Used this after wash, and blow dry. Hair is more straighter and less frizzy. Helps to get back the straight look temporary. Something to replenish the keratin and last abit longer. Like this product!

This product is like a leave-in conditioner and heat protectant all in one. Makes my hair soft and manageable. It make doing my hair so much easier and faster. It's expensive on the Canadian Amazon site but worth the money.
