Which hair type is longer, coarser, and pigmented?

• A. Vellus hair
• B. Lanugo hair
• C. Terminal hair
• D. Pheomelanin hair

Answer: (C)

Longer, coarser, and pigmented hair is terminal hair. This hair type grows in areas such as the scalp, eyebrows, armpits, and pubic region, especially after puberty when androgens drive the change from finer, lighter hair. Vellus hair is the opposite—fine, short, and lightly pigmented—while lanugo is a soft fetal coat that is typically shed before birth. The term pheomelanin hair isn’t a standard category for hair types; it refers to pigment type rather than a distinct hair texture or length. In the context of laser hair removal, terminal hair is the most recognizable target because its thickness and pigment make it more detectable and responsive to treatment.
