Have used it before for roots when I coloured my hair.
Have gone natural and hair is basically white. Problem was as you get older your hair gets thinner and my scalp was obvious as my hair was white.
I remembered Boost and Blend and checked out colours. I bought the darker silver/grey and Can’t believe what a difference it has made. You can’t see any pink scalp and my hair looks as thick as it did when I was younger.
Silky Silver Grey
