Hair bulb

The hair bulb, also known as the hair follicle, is the lower part of the hair rootThe hair bulb, located in the deepest region of the hair follicle, has an onion-like structure and surrounds the dermal papilla, a small, cone-shaped structure containing blood vessels that supply the hair bulb with nutrients and oxygen. The hair bulb plays a crucial role in hair growth, as it contains the cells that divide and form the hair.

Components of the hair bulb

  • Matrix cells : These are located in the hair bulb and are responsible for the production of new hair cells. The rapid division of these cells is what makes the hair grow.
  • Melanocytes : Within the hair bulb, these cells produce melanin , the pigment that gives hair its color. Different amounts and types of melanin result in the various hair colors.
  • Hair papilla : Contains the blood vessels that supply the matrix cells with the necessary nutrients for hair growth.

Functions of the hair bulb

  • Hair growth : The hair bulb is where hair is formed. The activity of the matrix cells in the hair bulb determines the speed and pattern of hair growth.
  • Hair color : The melanocytes in the hair bulb determine the color of the hair through the production of melanin.
  • Regeneration : The hair bulb enables the cyclical process of hair growth, which is divided into phases of growth (anagen), transition (catagen) and rest (telogen) before the hair falls out and the cycle begins again.

Health and Care

The health of the hair follicle is crucial for strong and healthy hair. Factors such as diet, stress, hormonal imbalances, and genetic predisposition can influence the health of the hair follicle and thus hair growth. A balanced diet rich in vitamins and minerals supports the health of the hair follicle. Products and treatments that stimulate the scalp and promote blood circulation can also have a positive effect on hair growth.

Problems of the hair bulb

Disruptions in the function of the hair bulb can lead to hair loss and other hair problems. Androgenetic alopeciaHereditary hair loss, also known as ovarian alopecia, is one of the most common causes of hair loss, affecting the hair follicle by shortening the hair growth phase. Other conditions such as Alopecia areata, one Autoimmune disease, which leads to circular hair loss, also directly affect the hair bulb.

Caring for the hair bulb and surrounding structures is essential for maintaining healthy hair growth and overall hair health.
