Went to the hairdressers to have balayage done on my dark brown hair and they turned me blonde. Nothing like the pic I showed them. Came home in a panic and dyed it with the only box dye I had at home which was mahogany but hate it still... Just want it back to being brown... If I pick up a dark brown box dye tomorrow and dye it will it fix it? Which brand is better? Don't want to go back to hairdressers in case they mess it up even more Am close to tears, loved my hair until now. Help please
