I had my hair done on 11/6 with Dana. I asked for a balayage which at first In salon I did like the way it looked. But once I washed my hair I realized there was too much brown put in it and it looks like I have roots that have been growing out for months. I would have emailed sooner but I just had a surgery and have been recovering. When I am feeling better I would like to come in and have my hair have more highlighting put in it as I am not pleased with results. I have been coming to this salon for years and am a loyal customer. Thank you and I hope you can help me rectify my situation.
