How many hairs does a pore grow? Why?

There is more than one hair follicle in a pore, and there is a hair in each hair follicle, so there can be several hairs in a pore. In fact, there is only one hair in a person's hair follicle, and in a few cases, there are two hair follicles. More than two hair follicles are extremely rare. There is also a kind of hair follicle with several hairs, which is a rare hair follicle deformity Pilimultigemini, which shows that a hair follicle grows multiple hairs.

A hair follicle has only one hair, but a unit does have multiple hairs, and a unit is not a hair follicle. When transplanting hair, a unit is a hair follicle unit (hair follicle unit, or hair follicle group). Generally, 1 to 4 hair follicles gather together to form a unit, and hair grows from a pore, but in fact each hair has its own hair follicle.

Extended data:

Hair follicle unit means that different numbers of hair follicles (generally 1-4) gather together to form a hair follicle unit, which protrudes from a pore. Several hair follicles grow hair together, which often makes people mistakenly think that these hairs grow from one hair follicle.

A hair follicle unit is equivalent to a hair family. Family members may have one hair or five hairs, but the intervals between these hairs are different and the growth cycle is different.
