Abstract in brief

  • The study tested whether low-level laser therapy (LLLT) using red light lasers and LEDs could promote hair growth in men with androgenic alopecia, with participants using a helmet-like device at home for 16 weeks.
  • Results showed that men who received the active laser/LED treatment experienced a significant increase (about 39%) in hair counts compared to the placebo group, with no reported side effects.
  • The findings suggest that LLLT is safe and potentially effective for stimulating hair growth in men suffering from hair loss.
