Friday I went to a casting for a hair show, granted I chose not to participate.
While there I noticed most girls were very young with very "normal" hair volunteering for very "not normal" hair haircuts.
I went through many rebellious states in my youth - including punk/hardcore. I had a mohawk. I colored my hair ever color imaginable. And I informed these girls of what was going to happen to their hair based off of my experiences.
This being said, if you ever agree to do a hair show I implore to talk to the stylist about the cut/color to see if it will work for you and about how the upkeep it will require - especially keeping your hair healthy!
A few years back I would have jumped at the chance but now my professional self held me back for I know purple, pink, and yellow hair is not for me.
