Hi, I usually dye my hair a red/brown colour but this time I put a medium brown over it and it's gone really really dark! I've phoned hairdresser (toni and guy) and they say they can do a 'cleanse' using a shampoo with bleach in it and then put in lots and lots of highlights, however I'm afraid I'll end up with hair the colour and texture of straw, has anyone ever had this done or are there hairdressers about who could reassure me?
Had hair cut on Saturday and discussed highlights but I've done the dye since then
