INVERTO ONE 180ml for Long Hair Complex Brazilian Keratin Hair Treatment Blowout Professional Results Straighten and Smooths hair Formaldehyde-Free Queratina Keratina Brasilera Tratamiento Keratin

Having Keratin treatment done at the hairdresser has become so expensive, in excess of £130 for my hair. I decided to try this and it works beautifully. The whole process took about 3 hours, but it is so worth it. I have very frizzy fuzzy and dry long hair. Take care to use gloves and wear and old t-shirt or use protective equipment as this stuff stings and itches if it touches your skin. At first when applied, the product actually does not smell bad. However, when you dry your hair, and shortly afterwards (perhaps an hour or 3) once you are finished with the straightening process (take breaks.... it kills your arms) you will start getting a wiff that is hard to describe. Burnt wet dog hair and nuts? Not sure, but it is certainly not lovely - HOWEVER it will go away after the first wash... I didn't wash mine immediately once done, but you 100% can as per the instructions, I just couldn't because I have kids and they were already wrecking the house for 3 hours!! I washed it 2 days later, then got some more of this burnt wet dog hair and nuts smell, but it's gone away since I dried it and now I cannot smell it anymore. My hair is beautifully straight, soft, silky and SO much easier to dry and style literally within 10-15min. I would do this again for sure!

Great, easy to use and if you follow the instruction to the letter it works. I did not experience the burnt dog smell others mentioned but I used what was left of the clarifying shampoo when I did my first wash the next day.

It smells bad when you sweat and also when you wash itIt made it straight and it was great, until two days later I went to the gym and started sweating, then my hair starting smelling bad, really bad, like rotten eggs.I went home and took a shower with special shampoo for keratine, and the smell continues, not going to buy this again, as I read online that a true keratine treatment will not leave a smell. I hid the smell with dry shampoo and perfume.I will buy an other brand next time.

The product is good, it worked on my hair. My hair type is thin, but it didn't burn my hair despite having it on for 90 minutes. The only thing I didn't like is the smell, it stayed longer than I expected. However, it does its magic which is more important, my hair is soft, shiny and straight. I was not able to take a picture of my before and after hair, but i convinced my friends to buy the product by just seeing my hair.

This is the second time I've used Inverto One, it has purple in it, so highlighted hair does not go orange.The first two photos are before, the second two after I've washed it. I followed all instructions, did it myself, it wasn't difficult, as you keep the product in your hair for 90 minutes, then wash it out with warm water (no shampoo). I did this thoroughly, then blow dried my hair as usual (which was easy as there wasn't any sticky product in it). Then I sectioned my hair and flat ironed it. I used my normal GHD flat iron, which only goes up to 185 deg C. The reason I did this was to also prevent my hair from going orange, which it didn't. Its the high heat combined with keratin that strips any colour out of your hair and makes it an awful copper colour. The lower temperature of the flat irons and the purple in the Inverto One (which they've increased the intensity of in the last year) definitely does the trick.It was not difficult to pass the flat irons at least 8 - 10 times through sections of my hair myself. And you can see that my hair is quite long.Its been raining since I washed and flat ironed my hair (it was straight enough, no frizz either, to not flat iron, but they recommend that you do in the beginning), and no frizz in the rain or damp ! My hair feels fantastic, its silky and the condition is definitely improved.I can't recommend this product enough. And its easy enough to do yourself. It hardly gave off any fumes (I didn't even notice them, perhaps because the temperature of the flat irons wasn't extreme). The hair has a bit of a smell (as with all keratin treatments) but after the first wash it's gone.

I have been having Keratin blowouts for the last 7 both in the salon and doing them myself at home. What I love about this product is how simple and odour free it is. Unlike a lot of the products available there is no smoke and fumes with Inverto One as you rinse it off BEFORE drying and using the flat irons. It’s so simple and only takes a couple of hours for the whole process, unlike some treatments that have to be dried and straightened into the hair and then left on for 3 days. With Inverto One you use the shampoo, thoroughly dry your hair, shake the product well, apply it all over your hair and comb through, put a shower cap on for 90 mins, thoroughly rinse the product out, dry straight and then use the flat irons - done. This is now going to be the home treatment that I use. No mess, no smoke, no smell, just straigh, soft, shiny hair. I am half caste and naturally have tight curls.
