DD has a formal thing at short notice. She has red dye in her hair which needs to come out or she’ll feel like a dick.
She’s using head and shoulders. Anything else we can try? I’m seeing mentions of vinegar and bicarbonate of soda online but don’t want to muck about with something that might not work/wreck her hair.
It’s a 12-15 wash one and it’s had about ten washes. It’s normally out by now!
