I’ve been wanting to dye my greying hair grey for a while and have let it grow out for a bit so I can see how much grey is in there. I started going grey in my 20s and I’m just fed up of dying it. The front of my hair around my face is super light but further back there is still a fair bit of dark brown/black (original colour - the reddy tone is dye). Does anyone know how much hassle it would be to dye it grey from its current colour, and how often I’d need to get it redone? Does it matter that there is still a lot of dye on the lengths? In my mind it wouldn’t look as bad growing out if it was dyed grey (better than grey roots with the darker ends). The second pic is my inspo.
