I normally have my hair cut and coloured every 4 weeks. I missed 3 appointments during Stay at Home. As my bangs got longer, I had to pull my hair back with a hairband and stray silver hairs started becoming visible at the crown. After about 8 weeks, I used Clairol Root Touch Up. When I saw my hairdresser at week 13, I said "What do you think of my colour?" She said "Wow, that's held up really well." If she can't tell the difference, why am I paying for professional colour rather than $7.95 at Walmart?
