Between what ages does scalp hair rapidly grow?

1. 10-20

2. 15-30

3. 25-40

4. 30-45

The correct answer is: 15-30

Scalp hair growth is affected by various factors such as genetics, hormones, nutrition, and overall health. Generally, hair growth tends to be faster during young adulthood (late teens to early 30s), which is why the correct answer is B. Option A (10-20) is incorrect because hair growth is not fully developed during puberty. Option C (25-40) is incorrect because hair growth begins to slow down as we age and approach middle age. Option D (30-45) is incorrect because although hair growth may still occur during this time, it is not considered to be rapid growth.
