I've not heard of this product before but having watched the video on the website, he got great results from it. I'm sure that not having to wait to wash your hair would be a big bonus to clients, but the fumes that came off the hair when he was straightening were phenomenal. Does this normally happen? - I haven't used a keratin treatment before.
Other things I noticed from the video were that I'm pretty sure he used GHDs, so there obviously isn't a thing about having to have straighteners heated to 230 degrees, and that it doesn't matter about having an SLS free shampoo apparently.
If you check the website for salons, none of them seem to have a website, and there is a huge majority of salons in Bournemouth/Poole, some elsewhere but none in the north which I thought was a bit weird.
How did they get your mobile number to text you?
