Permanently Waving Hair

Delta-keratin

Beta-keratin (correct)

Alpha-keratin

Gamma-keratin

The cooling or oxidation process causes the disulfide bonds in alpha keratin to reform as beta-keratin, resulting in a change in wave appearance. (correct)

The moist heat conditions cause the hair to stretch, resulting in a change in wave appearance.

The reduction of disulfide bonds in alpha keratin using a reducing agent causes the hair to become permanently waved.

The breakage of disulfide bonds in alpha keratin using moist heat causes the hair to become permanently waved.

Moist heat breaks the disulfide bonds in alpha keratin, allowing them to reform as beta-keratin.

Moist heat has no role in the process of permanent waving.

Moist heat reduces the hair's elasticity, making it easier to manipulate during the waving process.

Moist heat causes the hair to stretch, resulting in a change in wave appearance. (correct)
