What is saw palmetto?
Saw palmetto is a plant extract believed to block 5-alpha-reductase, the enzyme that converts testosterone to DHT — a key driver of androgenetic hair loss.
It is often used as a natural alternative to medications like finasteride, with fewer reported side effects.
Red light therapy can complement saw palmetto by targeting the follicle directly to reduce inflammation and support cellular energy metabolism.
