Red Light Therapy (LLLT)
Decent evidence for mild collagen stimulation and hair growth; consumer panels are often underpowered.
B
Evidence grade B
At least one good RCT or consistent controlled studies
Mechanism
630–850nm photons are absorbed by mitochondrial cytochrome c oxidase, transiently boosting ATP production and downstream fibroblast activity.

The full read
Clinical trials with professional-grade devices show modest improvements in skin complexion and collagen density, and LLLT is FDA-cleared for androgenic alopecia. The catch: many home panels deliver a fraction of the studied irradiance. Fine as an adjunct if you already own one; not a first purchase.
