The root of the hair is the portion of the hair that is embedded in the skin. It is located at the base of the hair follicle. The root of the hair is covered by the hair follicle and the hair shaft. The hair follicle is a structure that contains the hair root and the sebaceous gland. The sebaceous gland is a gland that produces sebum, which is a type of oil that lubricates the hair and the scalp.

What surrounds the root of the hair?
The root of the hair is the part of the hair that is embedded in the skin. The root is surrounded by the hair follicle, which is a tubular structure that extends from the surface of the skin to the root of the hair. The hair follicle contains the sebaceous gland, which produces sebum, a natural oil that lubricates the hair and the scalp.
What structure protects hair roots?
The hair follicle is a small, tubular structure that extends from the surface of the skin to the base of the hair. The hair follicle contains the hair root, which is the portion of the hair that anchors it to the skin. The hair root is surrounded by a layer of tissue called the hair follicle sheath. The sheath is responsible for protecting the hair root and keeping it moist. The sheath also contains a number of oil glands that produce a fatty substance called sebum. Sebum helps to condition the hair and keep it healthy.
What is the stuff on the root of hair?
The root of hair is the part of the hair that is embedded in the skin. It contains the hair follicle, which is the structure from which the hair grows. The root is surrounded by the hair follicle canal, which is filled with the hair’s natural oil, sebum.
What is the white thing at the end of a hair?
The white thing at the end of a hair is the hair’s shaft. The shaft is the part of the hair that is visible above the skin. It is made up of three layers: the cuticle, the cortex, and the medulla. The cuticle is the outermost layer and is made up of keratinized cells. The cortex is the middle layer and is made up of protein. The medulla is the innermost layer and is made up of cells that are filled with air.
What is a hair root sheath?
A hair root sheath is a protective layer that surrounds the hair root. It is made up of protein and helps to protect the hair root from damage. The hair root sheath also helps to nourish the hair root and keep it healthy.
What are hair bulbs?
A hair bulb is a structure at the base of a hair follicle that contains the cells that produce hair. The bulb is surrounded by a sheath of epithelial cells that produce the hair shaft. The bulb also contains the dermal papilla, a structure that contains blood vessels and nerve endings and stimulates hair growth.
What surrounds the hair follicle?
The hair follicle is the part of the skin that anchors the hair and is responsible for hair growth. The follicle is surrounded by a number of structures that play a role in hair growth and health.
The outermost layer of the follicle is the epidermis. This layer is responsible for protecting the follicle from the elements and from infection. The epidermis also produces a protein called keratin, which helps to form the hair shaft.
The dermis is the layer of skin beneath the epidermis. This layer contains the blood vessels that supply the follicle with nutrients. It also contains the sebaceous glands, which produce an oil called sebum. Sebum helps to keep the hair shaft lubricated and healthy.
The follicle is also surrounded by a layer of muscle called the arrector pili. This muscle is responsible for causing the hair to stand up when it is cold or scared.
The follicle is a complex structure and its role in hair growth and health is still being studied. However, the structures that surround the follicle play an important role in keeping the hair healthy and looking its best.
