I'm 34 and have been dyeing my hair to cover grey hair forever! I started going grey around 20! I use to be able to do it every 4 weeks but recently it's like every 2! I don't j own if they've changed the dye or my hair is just going greyer quicker tbh. I use garnier olia frozen brown. Can anybody recommend any good home dyes? I did go to the hairdresser a few times but tbh it came back just as quick!
