What is collagen?
Collagen is a structural protein that provides strength, elasticity, and integrity to the skin and scalp, creating a healthy environment for hair follicles.
It supports the dermal matrix around follicles and helps maintain scalp tissue resilience, especially as the body’s natural collagen production decreases with age.
Red light therapy may help stimulate collagen production, indirectly supporting hair growth by enhancing scalp health and nutrient delivery to follicles.
