This LED Hairbrush Will Help You Grow “Thicker, Fuller” Strands & Has Users Ditching Serums

It’s rare for a beauty trend to catch on with both editors and everyday shoppers—but LED hairbrushes are doing exactly that. Hair growth questions come up constantly, and lately, one topic keeps popping up: light-powered brushes designed to support thicker, fuller strands from the scalp up.

Skin Gym explains that LED hairbrushes use red or near-infrared light to penetrate the scalp and stimulate hair follicles at a cellular level. That stimulation helps encourage a longer growth phase in the hair cycle, which can lead to denser-looking hair over time.

They’re often recommended for people noticing shedding, thinning, or general fallout, especially when consistency is key.
