Most salons will not cut hair once they find lice. There is a lot of confusion about the rules and guidelines for hair salon and head lice. According to the Oregon Health Authority Board of Cosmetology, hair salons may provide over the counter treatment for head lice and will not be punished for doing so as long as the Board’s statutes and rules are followed. There are no rules regard cutting hair with lice, but most cosmetologists or barbers will not do it.
