What is hair cycle dysregulation?
Hair cycle dysregulation refers to an imbalance in the natural phases of hair growth (anagen, catagen, telogen), which can lead to excessive shedding or inhibited regrowth.
Triggers for dysregulation include stress, hormones, medications, or underlying health issues. When the cycle is disrupted, more hairs may enter the resting or shedding phases prematurely.
Red light therapy supports hair cycle normalization by encouraging follicles to re-enter the growth phase and reducing extended dormancy, making it a promising approach for restoring balance and density.
