So I've seen provoke are now selling a brunette version of their shampoo so got me thinking I'd like to use that or something similar to add a bit of omph to my hair.
I've only got the odd grey hair but it grows fast and I just can't be doing with the faff of dying my hair every month, it's thick too so takes two boxes a time and a few months it'll be 3 so thought a shampoo may be better, any ideas where to get such products or reviews please?
