INVERTO 60 Advanced Gel Complex Brazilian Keratin Hair Blowout Treatment Formaldehyde Free Straightening Smoothing and Repairing Damaged Hair Keratin Research (Long hair-180ml)

WOW! Fantastic product! I cannot believe that I did this myself! I have very long hair so I ordered 2x 6oz bottles just in case. Surprisingly, I only used about 5oz of product. I applied using the "curly" method as my hair is already pretty straight and I just want to eliminate frizz. It smells amazing and did not irritate my eyes at all although my scalp did tingle a little bit (nothing major). The whole process took exactly 3 hours, no longer than what it would take at the salon. However the salon is at least $350 (including a long hair surcharge) + tip, which turns out to be $420. This product will save me THOUSANDS plus the time I would have spent commuting to the salon. Thanks for an easy and effective at-home keratin treatment! I hope it lasts the 3-9 months as claimed.UPDATE: 3 months later and my hair still looks great! Washing 1-2x per week with sulfate free products.

I live in Hawaii. It is super humid every day and my hair usually frizzes and triples in volume if I don't braid it. This product is amazing and a lifesaver.I followed the instructions for the super straight type effect. I have shoulder length hair, and almost never straighten it because in this weather there is no point to even try. The only thing I didn't do is straighten it after the first couple washes as it instructs.My hair is frizz-free. I let it down in this weather and it doesn't pouf up. It straight, shiny, soft and a little wavy just how I wanted it. I'm very impressed with the results.

Not the best

It is the Best keratine at-home treatment I’ve ever used! My frizzy and dry hair went so shiny, healthy, and no dryness or frizz as it is done in the salon! Great product! It is easy to use and worths the money!

I am not a hair dresser and was so worried about doing my own keratin, but I just can't keep throwing away thousands of dollars every year on keratin treatments. (I have had over 20 over the years and this product is EXACTLY the same as the salon). I followed the directions exactly- even using the clarifying shampoo before, and the results are stunning. I'll never go back to the salon for keratin again. This saves time and money and us top quality. I had a fan ready but there was no toxic smell, it's a new different formula :)

My hair is dry, brittle, coarse and removed all my color. It only lasted a month. As soon as the humidity hit, it swelled up like it normally does. Very disappointed! Not worth the time or the money.

I had used many others keratin this one deft does not work , is been less than a month and my hair looks frizzy Messy

Thi product is amazing 100% recommended, after wash out my hair this is how it looks like and I naturally have curly hair and after using this keratin treatment is all straight and soft how I like. I have to say that I had try so many different keratin treatments but this one is definitely my favorite, and is easy to use. Buy it now!
