The laser hair growth cap uses medical‑grade 650nm, 5mW low‑level laser therapy. Medical soft laser diodes are evenly distributed to fully cover the balding area and boost hair growth.
Main unit and battery are separated, eliminating risks to the head caused by battery issues. Powered by a power bank (5V 2A) for high safety.
Fashionable, sporty cap design with detachable and replaceable structure. Powered by a power bank (5V 2A) for more convenient power access.
Seborrheic alopecia, hereditary alopecia, stress‑induced alopecia, postpartum alopecia, androgenetic alopecia.
