In which phase of hair growth does the hair detach?

The phase of hair growth during which the hair detaches is known as the exogen phase. In this phase, the hair follicle is preparing to shed the mature hair. This is a crucial part of the hair growth cycle as it allows for new hair to emerge.

To elaborate, during the anagen phase, hair is actively growing and is not detached. In the catagen phase, the hair transitions and begins to retract, but the hair is still anchored to the follicle. Lastly, while the telogen phase involves the hair being in a resting state prior to shedding, it is the subsequent exogen phase that specifically mentions the detachment of the hair from the follicle, signaling the end of that hair's life cycle. Understanding these phases helps comprehend the natural processes hair goes through.
