Got a hair appointment this week. My hair is shocking! I had it blonde (dyed) most of my life (mid 30s now). Then I just decided one day to put shop bought brown dye all over. I hated it. I stopped dying it for about three years. I trim it now and then but that's it. So I've got half natural and half dyed hair. I told them on the phone what I wanted and they mentioned they won't be able to dye it back blonde. So, I want it blonde again...but what can/will they do??
