Explanation:

Question 7

• Option a: Scalp massages do not increase hair growth. They may improve blood circulation but not directly cause more hair growth.
• Option b: Gray hair is not coarser than pigmented hair.
• Option c: Hair growth rate is indeed determined by genetics. Genetic factors play a major role in how fast hair grows.
• Option d: Cutting hair does not make it grow back faster and darker. Hair growth rate is mainly genetic, and cutting just removes the dead part of the hair shaft.

• The three growth cycles of human hair are anagen (active growth phase), catagen (transition phase), and telogen (resting phase).
• Option a: “return” is not a correct phase name.
• Option b: “growth phase” is too general, anagen is the specific growth - phase name.
• Option c: “mature” is not a phase name.

• Option a: Elasticity is the ability of hair to stretch and return to its original shape.
• Option b: Porosity is the ability of hair to absorb moisture.
• Option c: Saturation is not the term for hair's moisture - absorbing ability.
• Option d: Density refers to the number of hair follicles per square inch of scalp.

Answer:

C. Hair growth rate is determined by genetics.
