Verified step by step guidance1
Understand the structure and function of hair follicles: Hair follicles are small, dynamic organs found in the skin. They are responsible for hair growth and undergo cycles of growth (anagen), regression (catagen), and rest (telogen).
Differentiate between scalp and eyebrow follicles: Scalp hair follicles typically have a longer anagen phase compared to eyebrow follicles. This means that scalp hair grows for a longer period before entering the regression and rest phases.
Consider the growth cycle duration: Eyebrow hair follicles have a shorter anagen phase, which results in shorter hair length compared to scalp hair. This is why eyebrows do not grow as long as scalp hair.
Evaluate the statement: The statement claims that follicles giving rise to eyebrows remain active longer than those of the scalp. Based on the understanding of hair growth cycles, this is not accurate.
Conclude the analysis: Since scalp hair follicles have a longer active growth phase than eyebrow follicles, the statement is false. Therefore, the correct answer is 'False'.
