How are the sebaceous glands associated with hair follicles?

Sebaceous glands are small, sac-like glands that are closely associated with hair follicles. They are found all over the body, except for the soles of the feet and palms of the hands.

Sebaceous glands secrete an oily substance called sebum, which helps to keep the skin and hair moisturized. Sebum also helps to protect the skin from environmental damage and infection.

Each sebaceous gland is connected to a hair follicle by a small duct. The sebum produced by the gland travels through the duct and onto the hair shaft. This helps to keep the hair healthy and shiny.

In some cases, sebaceous glands can become enlarged or blocked, which can lead to the development of acne. Acne is a common skin condition that affects people of all ages.

Here are some additional details about the relationship between sebaceous glands and hair follicles:

* Sebaceous glands are stimulated by hormones, such as testosterone. This is why acne is more common in teenagers and young adults, who are experiencing a surge in hormone production.

* Sebaceous glands can also be affected by diet and stress. Eating a diet rich in processed foods and sugary drinks can contribute to acne. Stress can also trigger acne flare-ups.

* Sebaceous glands play an important role in keeping the skin and hair healthy. By understanding how these glands work, you can better care for your skin and hair.
