Review: Takes some effort BUT works perfectly! - 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!
Review: THIS PRODUCT IS THE ANSW(E)R !! - 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.

## Questions & Answers

**Q: How long do you have to wait before washing your hair?**
A: I usually leave it for three days. I definitely would recommend this product.

**Q: how long after can you colour hair**
A: Hi so it's best to always colour your hair first,then do the keratin treatment. If u do it the other way round your colour might not be even but more importantly it will impact on the keratin. So colour, then keratin. If u have already done the keratin you need to wait 2 weeks before u colour it. Hope this helps

### ⭐ DONT BUY ... IT SMELLS AFTER WASHING
*by M***E on 2 October 2023*

It smells bad when you sweat and also when you wash it It 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.
