Permanent Waving And Chemical Relaxing

Question 1

Two steps of permanent waving process

Answer 1

Wrapping the hair on a perm rod

Perm solution/neutralizer

Question 2

Is it important to do an elasticity test before perming hair?

Answer 2

Yes!

Question 3

In permanent waving, the size of the rod determines

Answer 3

The size of the curl

Question 4

Straight rods produce a

Answer 4

Uniform curl

Question 5

Soft bender rods are usually

Answer 5

12 inches long with uniform diameter

Question 6

It is common practice to use a base section that is wiser than the perm rod. True or False

Answer 6

False

Question 7

Base direction refers to the angle at which the rod is position on the head

Answer 7

Horizontally, vertically, or diagonally

Question 8

Why is it important to wrap in the natural direction of hair growth?

Answer 8

Because it causes the least amount of stress on the hair

Question 9

What are the two methods of wrapping the hair around a perm rod?

Answer 9

Croquignole

Spiral

Question 10

In which wrapping method is the hair strand wound around the rod, going from the ends to the scalp?

Answer 10

Croquignole

Question 11

Which wrapping method produces tighter curl at the end and larger curl at the scalp?

Answer 11

Croquignole

Question 12

What is a double rod or piggy back wrap and when is it beneficial?

Answer 12

Hair is wrapped on one rod from the scalp to middle of the hair shaft, another rod is used for the remaining. It allows for better penetration for extra long hair

Question 13

What does and alkaline permanent waving solution do?

Answer 13

Soften and swells the hair

Question 14

Once the waving solution is in the cortex, what occurs?

Answer 14

Breaks the disulfide bonds and reduction occurs

Question 15

What is a reduction reaction

Answer 15

Involves either the addition of hydrogen or removal of oxygen

Question 16

What is a reduction reaction in a permanent wave?

Answer 16

Addition of hydrogen

Question 17

What is the reducing agent used in perming waving solutions

Answer 17

Thio

Question 18

What is thioglycolic acid?

Answer 18

Most common reducing agent

Question 19

Strength of permanent waving solution is determined by

Answer 19

The concentration of thio

Question 20

The new chemical created is called

Answer 20

Ammonium thioglycolate

Question 21

Which hair type will need a more alkaline solution to achieve permanent waving?

Answer 21

Coarse, resistant hair

Question 22

Most alkaline waves have a pH between

Answer 22

9.0-9.6

Question 23

True acid waves are activated by what

Answer 23

Outside heat source, usually hood type dryer

Question 24

What information do you obtain from preliminary test curls?

Answer 24

1. Correct processing time for the best curl development
2. Results you can expect from the type of perm selected
3. Curl results for the rod size/ wrapping technique you are planning to use
