In sintesi

Low-level laser therapy has strong, well-established evidence for supporting hair growth in androgenetic alopecia, backed by multiple meta-analyses and randomized controlled trials.

  • 49 out of 58 studies show positive effects, supported by 7 meta-analyses and 8 RCTs
  • Stimulates hair follicles through photobiomodulation at specific light wavelengths
  • Included in clinical guidelines as an evidence-based option for pattern hair loss
  • Available as at-home devices (caps, combs, helmets) and clinical in-office systems
