Dd13 has lovely dark brown, very fine hair. She has been on about dying it a bright colour for ages. I'm a natural blonde and have zero clue but gather that it is a harsh treatment and not usually recommended for under 16s
She understands and has suggested a compromise by way of her having the bottom few inches bleached and dyed, it's due a cut anyway, needs a few inches off.
I think it's unlikely a salon will do it and I am not that sure if I should do it, or where to start in terms of strong enough bleach to lift her colour.
