What is hair follicle miniaturization?
Hair follicle miniaturization is the progressive shrinking of hair follicles, resulting in thinner, shorter, and less pigmented hairs.
It is the primary mechanism behind androgenetic alopecia (AGA), where hormonal factors trigger a gradual decline in follicle health and hair production over time.
Red light therapy seeks to counteract miniaturization by improving mitochondrial function in scalp cells, stimulating ATP production, and promoting a more favorable environment for hair follicle repair and regrowth.

Biological Concepts
Dihydrotestosterone (DHT) is a potent androgen hormone linked to hair follicle miniaturization and androgenetic alopecia (AGA).
Anagen phase
Biological Concepts
The anagen phase is the active growth stage of the hair cycle during which hair follicles produce new hair.
Exogen phase
Biological Concepts
The exogen phase is the part of the hair growth cycle when hair fibers are shed from the follicle as a natural renewal process.
