RELAXER

The range of numbers on the pH scale is:

• 0 to 5
• 0 to 14
• 0 to 10
• 0 to 7

The process  of rearranging the basic structure of curly hair into a straighter form is:

• waving
• texturizing
• chemical softening
• chemical  hair relaxing

The active ingredient in all hydroxide relaxers is the:

• hydrogen ion
• peroxide ion
• keratin ion
• lithium ion

Sodium hydroxide relaxers are commonly called:

• metal relaxers
• no-lye relaxers
• lye relaxers
• medium relaxers

During the relaxer strand test, hair that is pressed to the scalp and continues to curl is:

• insufficiently relaxed
• sufficiently relaxed
• normalized
• overprocessed

The application for chemical relaxers should be started in the most resistant area, usually the:

• front hairline
• back of the head
• scalp area
• side area

Hair that has been treated with  hydroxide relaxers must not be treated with:

• normalizing solutions
• color shampoos
• thio relaxers
• conditioning solutions

Chemical services should not be performed if the scalp analysis shows signs of:

• abrasions
• porosity
• disorders
• tightness
