Designed to reform the hairs disulfide bonds, neutralizers have what effect on the hair?
Harden and shrink
Which of the following cannot be used to reform the hair after the relaxer is removed:

Break
The average pH range of a sodium hydroxide relaxer is : A) About the same as a thio relaxer B) somewhat higher than a thio relaxer C) somewhat lower than a thio relaxer D) highly acidic
Correct B) somewhat higher than a thio relaxer
When doing a retouch relaxer service, it is a good idea to:
A) Deeply condition the hair immediately prior to the service
B) have the relaxed hair damp
C) leave conditioner on previously relaxed hair during the service
D) have the hair wet
Correct C) leave conditioner on previously relaxed hair during the service
Chemical relaxers and permanent wave solutions have what effect on the hair?
A) Acid so they shrink and harden
B) alkaline so they swell and harden
C) alkaline so they swell and soften

Hair has been relaxed with a hot iron, then a chemical relaxer is applied, what is likely:
Hair will break
Straightening the hair with the use of a hot comb, pressing iron, etc., is known as:
Thermal straightening
Students test the heat of thermal tools on a piece of white tissue paper. This is to:
Avoid usage of excessively hot tools
Using extremely high heat on white, gray, lightened, or tinted hair may cause the hair to:

Usually, pressing comb handles are wooden, while the combs themselves are made of:
Copper and brass
When the hair is pressed on both sides, this is referred to as:
Hard press
A hard press is most suited for which type of hair?
Coarse hair
Find hair especially around the face/hairline, requires less heat and pressure and a:
Soft press
A hair press can be expected to last about:
Two weeks
After a thermal press and curl, how long should you wait to style the hair?
Until it has cooled
The best method to clean a curling/pressing iron is with:
Fine steel wool
Which part of the hair is most easily broken during a thermal straightening service?
Front or hairline
In a thermal press and curl, the stylist should begin the press:
At the nape, close to the scalp
When pressing gray hair, use:
Light pressure and lowest heat possible
When using hot irons on highly lightened hair, use:
Low heat
If the ends of the hair are not in the curling iron, the likely result will be:
And unhappy customer, fishhook ends
When using very hot irons on highly lightened hair, in addition to breakage, you will:
Scorch the hair
Thermal styling may be done on wigs made of:
