The Hair Growth Cycle is a continuous process that encompasses three distinct phases: anagen, catagen, and telogen. This cycle is essential for the natural growth and replacement of hair, with each phase contributing to the overall health and density of the scalp.

The anagen phase, or growth phase, is the longest stage, lasting several years. During this phase, hair follicles actively produce new hair, resulting in visible growth. The catagen phase is a brief transitional period lasting a few weeks, where hair growth slows, and the follicle prepares to enter the resting phase.

The telogen phase, or resting phase, typically lasts a few months. During this time, hair is shed naturally, making way for the next cycle of growth. Approximately 10-15% of hair follicles are in the telogen phase at any given time.

Understanding the hair growth cycle is vital for diagnosing hair loss conditions and developing effective treatment plans. Targeting specific phases with therapies can enhance hair health and stimulate regrowth.
