Ok so coronavirus has left me with huge roots and with no sign of salons opening, I’m not sure I can last out. I have brown, not quite shoulder Length hair that I get foil half head colours done in every 8 weeks. I have 3 colours: a bleach, a warm blonde and a brown to tie it in to the remaining natural hair. My next appointment was 30/3!! So, my roots are brown with sprinkles of grey but more at the front. What can I do at home please?
