What is the typical hair growth cycle duration?

The typical hair growth cycle consists of three main phases: anagen, catagen, and telogen. The anagen phase, which is the growth phase, can last anywhere from 2 to 6 years depending on various factors such as genetics, health, and hair type. During this phase, hair follicles actively produce hair, leading to significant length increase.

In contrast, the catagen phase is a short transitional phase that lasts a few weeks, followed by the telogen phase, where the hair rests and eventually sheds. While the duration of hair growth can vary among individuals, the 2-6 years span for the anagen phase is widely accepted, making it the most accurate representation of the typical hair growth cycle duration.
