The best hair mask Ive ever used, my hairdresser recommended it to me after the first time we bleached my hair and it completely changed the texture back to a soft, normal hair feel.
Hair looks stronger and feels great.



It is a fantastic mask, the protein helps to repair the hair and the keratin leaves it smooth and shiny.

Perfect product

I ordered a few items for merritts after finding this website in a Google search for kerastraight products. The delivery was quick and well packaged and I ordered both the protein and the moisture mask which I use alternately each week when I was my hair. It's much cheaper than going to the salon and it makes my hair silky soft as well as being and healthy. Will be buying the larger one again once I run out.


Can't live without it...

I had been having this done by my hairdresser but its just as easy to do it myself at home!! I've got long coloured hair which is normally a bit dry and never smooth. After using this my hair feels like silk and is ultra smooth without using straighteners!!
