I've had a few people ask me this lately, although I did answer it in one of the latest YouTube videos at
https://www.youtube.com/user/baldchick :)
People ask, why I didn't become a hair dresser since I love hair.
I did actually looked into going to school to be a barber or a hair stylist many years ago, but the reason that I didn't go was that the classes had a start time of 8 am sharp. Non-flexible. I could never attend as I have a child and I take him to school.
Fast forward years later, same thing. Also, I have a job. I can't afford to quit my job to attend school as a barber or as a hair dresser. The pay isn't very good in these fields either - so be sure to tip your barber or stylist well!
