Levart [38]

Answer: A. scalp hairs grow constantly throughout life.

Explanation:

Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells.  Hair are made up of protein called "keratin".

Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).

Scalp hair growth stops because of  follicle devitalization when the hair length become two or three feet.

Hence, the correct answer is A. "scalp hairs grow constantly throughout life".
