I made the biggest mistake, stopping in and having my short, blond hair highlighted. Having highlights done for over 35 years, I have never, ever sat under the dryer for more than 10 minutes. I have fine hair, so my regular hairdresser would only use a hand dryer, if at all.
Within 3 days my hair looked dry, in 5 days it started to turn yellow. It was so over processed I had to go to a "professional" salon for treatment. When I asked about the time, she said that a conditioner had been added.....not true. I guess you get what you pay for. I will never go in for anything again. Now back in Canada and hoping my hair can recover. My regular hairdresser will have a fit when she see's me.
