I've used keratin blowout treatments before but this one is truly amazing. I was skeptical about this brand as my other very popular brand was discontinued and I feared I would not get the same results. I need not have worried, this one is MUCH better! It was very easy to apply and did not make my eyes sting so much like the other brand did. I got my husband to apply it to my hair with a colour brush purchased at Superdrug for less than £2. My hair was an absolute mess, damaged beyond repair from over bleaching and this is no exaggeration but my hair felt like chewing gum when washing it and looked like a massive bale of straw when dried. I thought the only option was to have it all cut off and start again. I researched keratin treatments, found this one on eBay and felt I had nothing to lose by trying it. The instructions tell you GHDs are not suitable but I used mine and after 3 full days I washed my hair and could not believe the transformation. It's like I've been given a full head of new shiny frizz free hair. I'm over the moon and can't stop looking at it in the mirror... and to think I nearly had it all cut off! I did not have any gold particles in my hair but the brush was covered, easily washed out though! If you want amazing hair this is the product to buy, I wasn't bothered about it being straight and I did tie it up when I needed my hair out of the way, however it has come out lovely and straight and I've only used my GHDs to smooth over the fluffy stray bits. Drying time has more than halved. I'll be buying this brand again and again.
