What is a Capillus hair cap and how does it work?

A Capillus hair cap is a portable, low-level light therapy device designed to promote hair regrowth in individuals experiencing pattern baldness or thinning hair. It resembles a regular baseball cap but is embedded with medical-grade laser diodes that emit specific wavelengths of light intended to energize and stimulate dormant hair follicles. The mechanism behind its operation involves the principle of photobiomodulation, where the red light emitted by the lasers penetrates the scalp and encourages increased blood flow and nutrient delivery to the hair follicles. This process is believed to activate cellular activity and promote the growth phase of the hair cycle, potentially leading to thicker, healthier hair over regular usage. Users typically wear the Capillus hair cap for a recommended duration as advised by their healthcare provider, making it a convenient, non-invasive treatment option for hair loss management.
