What is the telogen phase?
The telogen phase is the resting stage of the hair cycle when hair follicles are dormant before shedding and renewing their growth cycle.
Disruptions that prolong telogen can lead to visible thinning and scalp exposure. Red light therapy helps shorten the telogen duration and promote quicker transitions back into the active anagen phase.
Normalizing telogen timing is critical for maintaining full hair density and minimizing excessive hair loss, making it a valuable target for therapy protocols.
