7. Get a Free Hair Cut

Beauty academies and colleges running hairdressing courses offer free or heavily discounted haircuts to "models" who don't mind getting their hair done by students in training.

Be sure to be specific about the type of hairdo you want to end up with and speak up during the procedure, if the student does anything that is likely to result in the hairdo from hell.

Students need to learn from their successes as well as their failures, and won't do so, unless you tell them.
