Combs and brushes used on clients should be:

Combs and brushes are tools that contact the hair and scalp, so they must be cleaned and disinfected between clients if they are nonporous and reusable, or discarded if they are single-use. Removing hair and debris and then disinfecting prevents the transfer of scalp conditions, infestations, and pathogens from one client to the next. Keeping a supply of properly disinfected combs and brushes ready supports both sanitation and smooth service. This links the haircare tools content to the infection-control rules emphasized on the exam.
