    When we think about our hair, we tend to focus mostly on the outer surface, the texture of the hair, the length, strength, etc. We put in a lot of effort to maintain the condition of our hair externally. However, a majority of the time we miss out on focusing on the most important part, which is the hair follicle.

    What Is A Hair Follicle?

    Hair follicle is a part of the skin which regulates the hair growth by bringing cells together and controlling their interactions with hormones and immune cells. Hair follicle is a dynamic organ in the human body, made up of around 20 different kinds of cells. It is a kind of sac like structure from which hair growth occurs. Structurally hair follicles consist of a papilla at the base made up of connective tissues, hair matrix around it, the root sheath and the bulge (possesses stem cells) at the outer sheath. The sebaceous glands can be found at the top of the follicle. However, these sebaceous glands will not be found on hair which are under the skin of your palm, soles and lips. A healthy and strong hair on your scalp can on an average grow up to 0.5 inches or 133 mm in a month.

    Anatomy Of Hair

    A hair is made of a number of parts that make up its structure that include –

    • Hair Shaft – The part of hair which is visible and emerges from the skin is known as hair shaft. The hair shaft is made up of 3 layers of attached, keratinized, dead cells
      1. Medulla – The medulla is the hair’s innermost layer but it is not found in all the hair on our body. But is mostly common in hair which are long and thick
      2. Cortex – The second or middle layer is known as cortex which is responsible for determining the hair’s texture, color and strength
      3. Cuticle – The cuticle is the hair’s outermost layer which helps in protecting the cortex. It is a colorless and thin layer
    • Hair Root – Part of the hair which lies just below the epidermis is called the hair root. There is both, an internal as well as an external root sheath which are covered by connective tissue which is an outer sheath. The inner root sheath is cylindrical in shape and its primary function is to mold the hair. While the outer sheath is derived from epidermis
    • Matrix – A collection epithelial cells and pigment cells is known as matrix. The hair matrix surrounds the papilla and is responsible for the growth of new hair
    • Papilla – The papilla is made of a number of blood vessels which help in providing essential nutrients that are required for the growth of hair

    Apart from this, some of the other structures of hair follicle are bulge, hair fiber, sebaceous glands, apocrine sweat glands, arrector pili muscles, etc.

    Functions Of The Hair Follicles

    The growth of hair consists of three stages (hair follicle cycle) – anagen, catagen and telogen. Before these phases begin, the follicular morphogenesis phase occurs which is basically the phase in which the follicles form.

    1. In the anagen phase, the hair follicles are involved in the process of hair growth. Known as the active phase, the hair follicles remain active during this phase for about 2-7 years. After this period, the hair follicles move into the catagen phase.
    2. In the catagen phase, the hair emerging from the hair follicle turn into club hair and during this phase the blood supply and the new hair growth cells are cut off from the hair.
    3. This is a two-week process after which the hair follicle goes into the telogen phase. This is the hair follicle’s resting phase. The hair follicle’s final product is the club hair which is a dead and fully keratinized hair.

    What Causes Infected Hair Follicles? 

    Infected hair follicles are medically known as folliculitis. The two main causes of infected hair follicle on head and other body parts are bacteria and fungus. When your hair follicles are damaged, it becomes more difficult for them to evade these bacteria and fungus. There are a number of day-to-day activities which can aid these bacteria to enter the damaged hair follicles and spread.

    Some of the ways bacteria enter include through the hats and beanies that you wear, shaving, excess sweat, makeup, excess sebum, etc. All of these can negatively impact your already weak follicles. It is very important to seek hair follicle treatment as soon as possible so that your condition does not worsen.
