My hair is naturally brown but I got blonde foils at a hairdresser and recently got it dyed dark brown with semi-permenant dye. I was wondering if anyone knew if hairdressers can wash semi-permenant dye out so that it is blonde again. I don't want to destroy my hair. Will it cause lots of damage? I want to be blonde again.

Semi-permanent color can leave a permanent tint on bleached or chemically lightened hair. If you've used a semi-permanent color over your highlights, a hairstylist may use a hair color remover to remove the color and then apply a toner. Hair color removers can make the hair brassy, therefore, they will need to re-color your highlights in order for it to look natural.
