A LED hair-growth panel combining 660 nm red light with 850 nm near-infrared light, designed to deliver low-level light therapy (LLLT) to the scalp for hair-regrowth support.
 
Dual-wavelength therapy: The 660 nm red light stimulates surface-level scalp cells to boost cellular energy, potentially reviving hair-follicle activity. 
Deeper tissue penetration: The 850 nm near-infrared light is intended to reach deeper scalp tissue — aiding circulation, reducing inflammation, and creating a healthier environment for follicles. 
Hands-free & full-scalp coverage: As a cap, it provides even, all-around exposure — convenient for regular at-home sessions without manual positioning.
Non-invasive and relatively low-risk: Red-light/near-infrared therapy (LLLT) is generally considered safe when used correctly; it avoids drugs or surgery and tends to have minimal side effects when wavelengths and dosage are appropriate. 
Potential benefits: May help reduce hair shedding, stimulate dormant follicles, improve hair density and thickness over time — particularly in early-stage thinning or pattern hair-loss.
