What is the sequence of stages in hair growth?

The correct sequence of stages in hair growth is Anagen, Catagen, and Telogen.

In the Anagen phase, which is the active growth phase, cells in the hair bulb divide rapidly, leading to the formation of new hair. This phase can last for several years, depending on genetic factors and other influences, determining the overall length of the hair.

Following the Anagen phase is the Catagen stage, which is a transitional phase. During this period, hair growth slows down, and the hair follicle shrinks, leading to the detachment of the hair from the blood supply. The duration of the Catagen phase is relatively short, lasting only a few weeks.

The final stage is the Telogen phase, characterized as the resting phase. In this stage, the hair is not growing but remains attached to the follicle until it eventually falls out and is shed. This phase can last for several months before the cycle starts again, and the hair enters the Anagen phase once more.

Understanding this sequence is essential for skincare specialists as it provides insight into hair growth patterns and can influence treatment decisions for hair-related concerns.
