Pili multi gemini refers to which phenomenon?

• A. Two hairs in one follicle
• B. One hair per follicle
• C. Three hairs in one follicle
• D. Hair splitting

Answer: (A)

Pili multigemini is when more than one hair shaft grows from a single hair follicle. This happens when the hair matrix or follicle structure creates multiple hairs that share the same pore, so you see two (or more) hairs emerging together from one opening. That makes the description of two hairs in one follicle the best match for this phenomenon, since a normal follicle typically produces one hair, and hair splitting refers to a hair breaking along its shaft rather than multiple hairs sharing a single follicle. While three hairs from one follicle can occur, the classic, most commonly described scenario is two hairs coming out of one follicle.
