i used this over faded special effects red dye and it came out really dark purple. it was nice but only lasted about 2 washes before turning a horrible murky colour. might work alot better on just bleached hair.

NOTE FROM BEEUNIQUE - Dyes should ideally be applied to a pale lemon or white hair in order to achieve the best results and for them to last as long as possible. Dyeing over darker or already dyed hair may cause colours to fade faster and give a different colour result.
