What is androgenetic alopecia (AGA)?
Androgenetic alopecia (AGA) is a common hereditary form of hair loss characterized by gradual thinning of scalp hair.
AGA involves progressive hair follicle miniaturization, where follicles shrink and produce finer hairs over time. Hormonal influences like dihydrotestosterone (DHT) play a significant role in this condition.
Red light therapy has emerged as a non-invasive intervention for AGA, offering a way to energize shrinking follicles, extend the anagen phase, and potentially reverse follicular decline.
