I am a pensioner - but don't look it - no wrinkles (genetic) and long very dark brown grey-free hair.
I would like to put some pink streaks on the lower few inches, and as a sort of under layer, if you see what I mean - so that occasional flashes of pink would be visible.
Any ideas as to how I might do this? - whether it might ruin my hair because I guess some bleaching would be required? - whether it is feasible? - could I DIY? - would it cost an arm and several legs?!
