Why is the telogen phase important in the hair growth cycle?

The telogen phase is a critical part of the hair growth cycle because it allows the scalp and hair follicles to rest. During this phase, which can last several weeks to a few months, the hair does not actively grow. Instead, it prepares for the eventual shedding of the hair that has completed its life cycle, making space for new hair to grow in the anagen phase, which is the active growth phase.

This resting period is essential for maintaining a healthy hair cycle. If the hair follicles are constantly in an active growth state without adequate rest, it could lead to stress on the scalp and potentially result in issues such as hair thinning or loss. Thus, understanding the telogen phase's role in providing rest helps beauticians appreciate how to manage hair health effectively, ensuring clients maintain vibrant and full hair.
