What are dermal papilla cells?
Dermal papilla cells are specialized cells located at the base of each hair follicle that regulate hair growth by interacting with surrounding stem cells and signaling molecules.
They play a crucial role in initiating new hair cycles and determining the length and thickness of individual strands.
Red light therapy can stimulate dermal papilla activity, promoting stronger and more sustained follicular growth over time.
