I would suggest you go to a Sally's Beauty Supply and talk with one
of the employees there. They have to either be in school or have been
to school (to do hair) in order to work there.
Tell them what you want to do and they will direct you down the right
path.
In case you are wondering you DON'T need to be a professional to shop
there. I shop there often enough that I have their Sally card it gives me
the same discount that licensed professionals get, and the card costs $5
a year, but you can get that back if you take that receipt back in to buy
other stuff.
I have been a Sally shopper for over 20 years.
