Question

Hair that has been pulled out from the roots can grow back under which of the following circumstances?

a) Only if pulled gently
b) Only if pulled in the same direction as hair growth
c) Only if pulled forcefully
d) Only if the hair follicle is not damaged

Answer 1

Hair can regrow after being pulled out provided the hair follicle remains undamaged, as follicles contain the necessary stem cells for hair growth.

Step-by-step explanation:

Hair that has been pulled out from the roots can grow back if the hair follicle is not damaged.

Hair growth originates within a hair follicle, where stem cells divide to enable hair regrowth after it has fallen out.

Accompanying the follicle is a sebaceous gland, which produces sebum to lubricate the hair, and this does not generally affect the hair's ability to regrow.

The manner in which hair is pulled, gentle or forceful, does not impact regrowth if it is not accompanied by follicle damage.
