Which of the following phases signifies the final stage of the hair growth cycle?

The telogen phase is recognized as the final stage of the hair growth cycle. During this phase, the hair is in a resting state, and it remains anchored in the hair follicle without growing. The telogen phase typically lasts several weeks to a few months, depending on individual factors such as genetics and overall health. At the end of this stage, the existing hair eventually falls out, making space for a new anagen phase to begin where a new hair follicle starts to grow.

In terms of the other phases, anagen is the active growth phase where the hair cells are rapidly dividing, leading to hair lengthening, which contrasts with the resting nature of the telogen phase. The catagen phase, a transitional period, entails the hair follicle shrinking and detaching from the dermal papilla but still retaining a connection with the hair shaft. Exogen refers to the phase where the hair is shed, which is an important part of the hair cycle but does not signify the final stage itself. Understanding these phases aids in comprehending hair health, growth patterns, and the effects of various treatments in skincare.
