I have a dark brown and blonde put through my mousey brown with the odd the grey hair. I can’t do anything about that blonde roots obviously. With hairdressers being shut for another nearly 2 months what can I do with it to make the best of the situation? What sort of colour root touch up should I go for? A mid brown? The dark is fading and won’t be able to match it... which one is any good? The spray? Or the very expensive colour wow? Any suggestions please?
