I have posted before about my 4 hour session with my poor hairdresser when I presented her with dyed dark red hair, having decided to give it all up and go with the grey!
Bleach, wait, rinse, result? A sort of pale apricot. Dry, bleach again, wait, rinse, dry then apply a sort of ash blond, wait, rinse, cut, finish.
As I said, 4 hours. My hair was of course very damaged, but loads of intensive conditioning stuff (applied at home) and it came back into good condition
I decided to give in to the grey because my hair grows incredibly fast, and I was fed up with having roots showing through within 3 weeks of a colour.
I'm now having a bit of fun with pink and purple colours, but ones that just wash out gradually over about 6 weeks.
Will probably only do it during the summer months, I already have a Russell Brown silver ready for the winter.
