karvanlähdösvaihe

Karvanlähtövaihe, often referred to as the shedding phase, is a natural and essential part of the hair growth cycle. This phase, also known as catagen, is a transitional period where the hair follicle begins to shrink and detach from the dermal papilla, the structure that nourishes the hair. During this time, the hair shaft itself stops growing and prepares to fall out.

The duration of the karvanlähtövaihe varies depending on the hair type and the body part. For example, the shedding phase for scalp hair is relatively short, typically lasting around two to three weeks. In contrast, hair on other parts of the body might have a different shedding cycle. This shedding is a normal process, and it's common to notice an increase in hair found on brushes, in showers, or on clothing during these periods.

Following the karvanlähtövaihe, the hair follicle enters the resting phase (telogen), where it remains dormant for a period before a new hair begins to grow. This cyclical nature of hair growth ensures continuous renewal of hair on the body. Factors such as genetics, hormones, and certain medical conditions can influence the length and intensity of the shedding phase, potentially leading to noticeable hair thinning if the balance of these cycles is disrupted. Understanding the karvanlähtövaihe is key to comprehending normal hair loss patterns and distinguishing them from potential underlying issues.
