Haarautumisvaiheiden refers to the various stages of hair growth, which is a continuous process that occurs in three distinct phases: anagen, catagen, and telogen. This cycle typically lasts about 2 to 6 years, with each phase having its own characteristics and duration.

The anagen phase is the active growth phase, where hair follicles produce new hair. This phase can last for several years, depending on the individual. During this time, the hair shaft grows from the root to the tip, and the hair follicle is nourished by the dermis.

The catagen phase is a short transitional phase that follows anagen. It typically lasts for about 2 to 3 weeks. During this phase, the hair follicle begins to shrink, and the hair shaft detaches from the root. This phase is characterized by a decrease in blood flow to the hair follicle.

The telogen phase is the resting phase, where the hair follicle is inactive. This phase can last for about 2 to 4 months. During this time, the hair shaft remains attached to the root, but no new hair growth occurs. The hair follicle is shed, and a new hair follicle begins to develop in the anagen phase.

Understanding the hair growth cycle is important for various hair care practices, such as hair cutting, styling, and treatment. Factors such as genetics, age, and overall health can influence the length and characteristics of each phase. Additionally, external factors like diet, stress, and environmental conditions can also impact the hair growth cycle.
