If you want to, it's ok.
Dyed mine red three times. XD Don't do it much anymore.
Oh, I have a habit of dying my hair XD my hair is growing to a gross brown again lol
Ha. XD Mine's a real dark brown/chestnut right now, and in the sunlight, I get some golden bits (Since I was born blonde but my hair darkened as I matured. XD).
if that's what you want so yes
