Which phase of hair growth is referred to as the active phase?

The active phase of hair growth is known as the Anagen phase. During this phase, hair follicles actively produce hair, and it is characterized by rapid cell division within the hair bulb, leading to the growth of new hair strands. The duration of the Anagen phase can vary significantly from person to person, lasting anywhere from two to six years or even longer in some cases. This extensive growth period is crucial for developing long, healthy hair.

Understanding the other phases is also important for context. The Telogen phase is a resting period where the hair is not actively growing, often lasting a few months before the hair falls out and a new hair begins to grow in the Anagen phase. The Catagen phase is a transitional stage lasting a few weeks, during which hair growth slows and the hair follicle shrinks. The term 'Resting' can be associated with the Telogen phase, emphasizing the inactivity during that time. Recognizing these distinctions helps in understanding the hair growth cycle and the significance of the Anagen phase in maintaining healthy hair.
