Hello,

my natural hair colour is dark brown but I have been highlighting it for a while now. I recently dared to go a bit further and asked my hairdresser to dye the growing roots blonde. It's now three days later and the colour looks awful! My hair is very fine and the colour is going slightly reddish now. Can I go back this week to dye it back to my dark colour or will it be too bad for my hair?

Thank you!
