hair structure/density/porosity/texture

Question 1

cuticle is:

Answer 1

the cuticle is the outermost layer of the hair. it protects the cortex and contributes up to 20% of the overall strength of the hair.

Question 2

cortex is:

Answer 2

The cortex is the middle layer and gives the hair the majority of its strength and elasticity. a healthy cortex contributes to 80% to overall strength of the hair.

Question 3

medulla is:

Answer 3

The medulla is the innermost layer of the hair. it is sometimes absent from the hair does not play a role in the hair coloring process.

Question 4

texture is:

Answer 4

Hair texture is the diameter of an individual hair strand. large, medium, small diameter hair strand translate into coarse, medium, and fine hair texture.

Question 5

density is:

Answer 5

hair density is the number of hair in a square inch space, it can range from thin to thick.

Question 6

porosity is and levels:

Answer 6

porosity is the hair’s ability to absorb moisture:
LOW POROSITY: The cuticle is tight.
AVERAGE POROSITY: The cuticle is slightly raised.
HIGH POROSITY: The cuticle is lifted.
