low-level laser therapy dual-wavelength LED wavelengths hair regrowth surface image analysis histological examination LLLT

TLDR Dual-wavelength laser therapy promotes better hair regrowth than single-wavelength treatments.

The study investigates the effectiveness of dual-wavelength low-level laser therapy (LLLT) on hair regrowth in mice, using light-emitting diodes (LEDs) at 670, 680, 780, and 880 nm. Conducted over 14 days, the research compared dual-wavelength combinations to single-wavelength treatments and an untreated control group. Results from surface image analysis and histological examination showed that dual-wavelength therapy significantly enhances hair regrowth compared to single-wavelength treatment and the control, suggesting its potential for improved hair regrowth. The authors reported no conflicts of interest.

community How true is the statement: dead follicles don't grow back?

in Research/Science 107 upvotes 3 weeks ago

Hair follicles usually go dormant rather than die, and treatments like finasteride, minoxidil, and hormone therapy can sometimes reactivate them, though results vary. Complete regrowth is rare, especially in long-term bald areas, but some individuals see significant improvement with these treatments.
