Which statement about systemic hair growth changes is incorrect?

• A. Hormonal Changes Can Affect Hair Growth
• B. Pregnancy Can Affect Hair Growth
• C. Frequent Brushing Is a Systemic Factor
• D. Menopause Can Affect Hair Growth

Answer: (C)

Systemic factors are internal, body-wide influences that affect hair growth, such as hormones, nutrition, illness, medications, and life events like pregnancy or menopause. These factors can change how long hair stays in the growing phase, how fast it grows, and how much sheds.

The statement about frequent brushing isn’t a systemic factor because brushing is a mechanical, local action on the hair and scalp. It doesn’t trigger the body-wide hormonal or metabolic signals that regulate hair growth, so it wouldn’t cause a true systemic change in growth patterns.

In contrast, hormonal changes influence hair growth cycles directly, so pregnancy and menopause can alter growth and shedding due to hormonal fluctuations. Pregnancy often prolongs the growing phase, sometimes making hair appear fuller, while postpartum shedding or menopause-related thinning reflects the body's hormonal shifts.
