Seems like hair coloring is really popular among college girls from what I've seen.
Changing hair color seems to be pretty big among some demographics
Yeah definitely, it may be controversial but it seems like bisexual/transgender/gay women do it all the time, at least from what I've seen.
Many hair colorings are done professionally.
It must look really good when done by a pro.
I agree, but sometimes it can be done independently within the home.
