reduces the swelling caused by the alkalinity
The perm pattern that includes a central rectangle and two sections at each side is the:
contour pattern
Hair is generally referred to as fine, medium or coarse when analyzing which of the following classifications?
texture
How do you use the bookend technique for end-paper placement?
uses one end paper folded in half.
End papers are important to control hair ends during the perming process and to:
used to control the hair ends and keep the hair smoothly wrapped around the perm tool.
At the end of the service, what should be done with open, unused perm solution?
Throw away any open, unused perm solution or neutralizer after use.
What type of perms process the fastest because of their higher pH?
alkaline perms process faster than acid waves
Which base control is the most commonly used during a perm service?
half-off base
Alkaline perms carry a pH of:
8.0-9.5.
The hair characteristics to assess in a pre-perm analysis are porosity, elasticity, texture and:
density
The rectangle wrap is also called the:
9-block pattern
Which test should be performed during a relaxer service to determine if additional smoothing is required?
The relaxation test, also known as the comb test
What is used to spread the chemical relaxer through the hair during the processing of a relaxer?
The back of the comb
Advise a client to not shampoo their hair within how many hours prior to a sodium hydroxide relaxer service?
48 hours
Virgin relaxers may be applied ¼” (.6 cm) to ½” (1.25 cm) away from the scalp because body heat from the scalp will:
