DD is in trouble at school for her hair colour, she used a semi-permanent before Christmas and it still hasn't entirely washed out (despite the box saying it would wash out within 10-12 washes).
I'm not sure I'll be able to get to a big Boots / Superdrug to buy Colourb4 by tonight. However the Superdrug website suggests using Vitamin C tablets with H&S shampoo.
Has anyone had any success with this method? She's had the colour on for 2.5 weeks now, it's faded but not enough.
