Need Sample Dialogues concerning "Hairdressing & Skin Care"

Hi!

I'm a newcomer teacher of English and I'm going to give a lecture on "Hairdressing & Skin Care (Business English)" at a vocatioanal high school. I'm planning to make use of sample dialogues in the lessons for the students to gain practice. If anybody could give me any addresses on the internet about the subject, I would be grateful.

Thanks already!
