folikülüne

Folikülüne is a term used in Turkish to refer to a hair follicle. A hair follicle is a small, pouch-like structure in the epidermis of the skin from which hair grows. It is a complex organ responsible for the production and growth of hair shafts. The follicle itself is comprised of several parts, including the outer root sheath, inner root sheath, and the hair bulb. Within the hair bulb, specialized cells called keratinocytes produce keratin, the primary protein that makes up hair.

The hair follicle is also associated with a sebaceous gland, which produces sebum, an oily substance that lubricates the hair and skin. Additionally, a small muscle called the arrector pili muscle is attached to the follicle, which can contract and cause the hair to stand on end, a phenomenon known as goosebumps. The cycle of hair growth involves several phases: anagen (growth), catagen (transition), and telogen (rest). The duration and characteristics of these phases vary depending on the location on the body and individual factors. Understanding the structure and function of the folikülüne is crucial in fields such as dermatology, cosmetology, and trichology, as many conditions and treatments relate directly to hair follicle health and activity.
