Hi all. For the last few years I have regularly had my roots done (blonde highlights, with bleach). My hairdresser uses foils. It costs me approx £80 every 12 weeks, and to be honest, I can't justify spending the money at the moment. I am new to the world of semi/permanent hair colour from Boots/Superdrug. Can anyone recommend a good product? I still plan to stay blonde. Thank you.
