I go here all the time...a friend recommended this school to me. Conveniently located just across the street from the Davisville Subway Station. Walking in you feel like you are at a professional salon, not a teaching school. It's clean and they use quality products on your hair. Prices run from $18.00 to $35.00 for a Shampoo & Blow dry (depends on the length and texture of your hair), and you get a nice scalp massage. I've had a few different students do my hair, and the teachers will jump in and finish your style off if it's not up to par. I've even had Mr. Fiorio himself spend some time on my hair on two occasions, he is very hands on and very good!
My rule of thumb when visiting hair schools is never get anything done that would freak you out if it didn't come out exactly as you would like, I'd prefer to pay full price at a reputable salon for those jobs.
Remember that this is a school, so sometimes it takes a while to get the job done, and you will have to explain your needs on every occasion.
