Went to Toni and Guy about a month ago for a T-section of dark blond highlights on my naturally light brown hair. Was persuaded to have a toner put in to 'enhance' my natural hair colour, but when the toner was taken off my hair had gone a uniform bright yellow. They tried to correct it with a darker toner, which turned my hair copper. Finally, the manager had to re-dye my hair back to its natural colour and re-highlight. The salon assured me that because toner does not contain bleach or ammonia, it cannot damaged hair.
However, since then, large clumps of my hair have been breaking off at mid-section. It looks awful - frizzy and terrible condition in a way that it was not before. Am I right in thinking that it has been over-processed? Am if so, do you think that I should have any recourse to compensation from T&G? (not sure what exactly - perhaps free haircut, conditioning treatment, or simply a refund for the botched dye job that appears to be responsible for this? )
