The hair characteristics to assess in pre-perm analysis are porosity, elasticity, texture and:

• styling

• length

The method of wrapping hair from the end to the scalp is known as:

The four basic toll positions in perming are on base, half-off base, underdirected and:

• off base

• overdirected

• highly directed

• one-time directed
