[This review was collected as part of a promotion.] This has helped somewhat with my hair coverage. I have white/greys and I'm not even 30! This alternative helps give it a tint and I get a good hair coverage without the need for hair dye, it does not really match my hair colour, I am dark brunette almost black however the shade was more of a rusty brown so when I sprayed on my greys, it gave me off shade between my natural hair and the tint. Also I did see it seep into my scalp, I felt more of the colour went in my scalp rather than on my hair. I did like the scent was not overpowering and it helped on days where I did not wash my hair.
