I'm trying to get it darker so I can do my blonde ombre that I've been wanting to do for months, however every time I'm dying it, the colour fades back to a light brown/ginger colour after only a few washes.
Is there a way of telling why it does it, e.g hair being too dry, or whether I need to just strip it completely??
Also I've also been to the hairdressers to have it dyed, thinking it's better than box dye and the same thing pretty much happened.
