I did a terrible job box dying my hair cherry colored... I'm such a cheapskate, I wanted to do it myself. I saw on Instagram that Salon 1226 participates in color correction seminars, so I went to them for help.
They were able to get me in on the same day with Tiffany. She turned my hair a beautiful shade of dark brown and the red came through as pretty undertones.
I highly recommend Tiffany and Salon 1226!
