How many hair follicles are in a square centimeter What does hair follicle mean

The hair follicle can be understood as the place where the hair grows, and the hair roots are inserted in the hair follicle. There is a gap between hair and hair, so there is also a gap between hair follicles, and how many hair follicles there are in one square centimeter is how many positions can be inserted in one square centimeter.

Hair follicles are the root of hair growth, only hair follicles can grow normally, and there are about 80-140 follicle units in one square centimeter of native hair, and if you transplant hair, you can probably achieve 60%-80% of the original hair, but the specific situation depends on the actual density of your hair, and it is best to go to a regular hair transplant institution for testing.

1. There are about 100,000 hair follicles on the human scalp, and because there are about 100,000 human hairs, there will be 100,000 hair follicles.

2. The hair follicle is a sac-like tissue surrounded by the root of the hair, the inner layer is the epithelial tissue hair follicle, the outer layer is the connective tissue hair follicle, the inner layer is connected to the epidermis, and the outer layer is connected to the dermis. Generally speaking, people cannot grow new hair follicles, which are the first cells that cause hair to grow. All hair follicles are born with a person and accompany them throughout their lives, and hair follicles cannot regenerate after death.

A hair follicle can only grow one hair, and the hair follicles in the human scalp are one, two, three, four or five in a group, and distributed in groups, and each group contains its own pores and sebaceous glands that nourish its own hair, that is, each capillary may have one to five hairs to grow, and this kind of hair follicle containing its own sebaceous gland as a group of units is also called follicular unit So the concept to be clarified is that not one hair follicle can grow multiple hairs, several hair follicles and leaning together to grow hair, It is often mistaken that these hairs grow from a single hair follicle. To put it simply, a follicular unit is equivalent to a hair family, which can be a single hair or five hairs, but these hairs are not spaced at different intervals and have different growth cycles.

Approximately 200,000 follicular units.

Normally, a hair follicle in the human body grows only one hair, but our hair follicles are often arranged together in groups, so it looks like a hair follicle has several hairs.
