Its
not at only one salon in London. I can think of at least 10 from the top of my head.!! I personally know a lot of hairdressers based in London who not only can do it, but have the experience to do a fantastic job..!!
The stylists that I know have been using this product for over 10 years now, it orginated from the far east but only arrived in england properly in the last few years. Almost every salon offer this system in the far east. It is as common as your normal cut and blow dry.
I have had my hair straighten using this system for 6 years continously. When this product is used correctly, the results are unbelieveable. The hair comes out softer, silkier and dead poker straight. No more blow drying after washing hair, No frizz, no kink, no more GHD...!! It is most definetly not like any other straightening system.
This product does not damage the hair. It is the hairdressers who has no experience in this product who damages the hair. So, like nails and everything else, finding the correct person to do it determines how good the results are.
It has been discussed on here before.
