It will pay to self advertise.

True story - my mom had been shopping for some hair products for Xmas and went into a salon to pick up some good shampoo/conditioner.  She found the stuff and when she went to pay, one of the hair dressers talked to her and offered to do her hair. (It has been some years since my mom has gone to a professional stylist.)

My mom was interested - she would really, really like to find a good stylist; but she turned the stylist down and here is why.

She said every stylist in that shop that day had bad hair.  She told the person that she would have taken them up on their offer, except that her own hair looked better than every stylist in the shop.

So maybe stylists should think twice before coming to work with scruffy hair.  From the customer's perspective, a stylist's own hair is often taken as a measurement of his or her skill.  And if the entire shop is below par, it can drive customers off.
