In which phase of hair growth does hair shedding occur?

The telogen phase is the resting phase of the hair growth cycle during which hair shedding occurs. In this phase, the hair follicle becomes inactive, and the old hair is retained in the follicle until it is eventually pushed out by a new hair developing in the anagen phase. This natural cycle ensures that hair can grow in a healthy manner, with old and damaged hairs being replaced.

During the telogen phase, which lasts for several weeks to months, approximately 10-15% of hair follicles are in this resting state at any given time. This phase is crucial for maintaining hair health, as it allows for the necessary regeneration and replacement of hair. After the telogen phase, the hair cycle will continue with the anagen phase, where new hair begins to grow.

Other phases of the hair growth cycle do not specifically involve shedding. In the anagen phase, hair is actively growing and the follicle is engaged in producing new hair. The catagen phase is a transitional phase where hair growth ceases, but shedding does not typically occur until entering the telogen phase. The exogen phase, sometimes considered a part of the telogen phase, refers specifically to the stage where the old hair sheds, but the terminology may vary and can
