Used colour B4 a few evenings ago, and it was like halloween a few days late, with my hair turning bright orange! Argh
I've put on a semi but am now concerned what happens after the 24 washes its meant to last for, does it wash out completely and will I be left with an orange crop or does it leave some of the colour in my hair and just fade?
Also i've heard that if you put a semi on top of a semi, it becomes permanent
is there any truth in that?
