Data of selected laser therapy
| Reference | Title | Therapy protocol | Result |
|---|---|---|---|
| Lanzafame et al. (2013) [22] | The growth of human scalp hair mediated by visible red light laser and LED sources in males | Source: TOPHAT655 (helmet-type laser & LED array) Wavelength: 655 nm Period: 60 times for 16 wk, 25 min per times for the global scalp |
Low level laser treatment for androgenetic alopecia is safe and effective, with a 35% increase in hair counts |
| Kim et al. (2013) [30] | Low-level light therapy for androgenetic alopecia: a 24-week, randomized, double-blind, sham device-controlled multicenter trial | Source: helmet-type laser & LED array Wavelength: 630 nm, 660 nm, 650 nm Period: every day for 24 wk, 18 min per times |
LLLT group showed significantly higher hair density and improved mean hair diameter |
| Lanzafame et al. (2014) [31] | The growth of human scalp hair in females using visible red light laser and LED sources | Source: TOPHAT655 (helmet-type laser & LED array) Wavelength: 655 nm Period: 60 times for 16 wk, 25 min per times for the global scalp |
Low level laser treatment for androgenetic alopecia is safe and effective, with a 37% increase in hair counts |
| Friedman and Schnoor (2017) [32] | Novel approach to treating androgenetic alopecia in females with photobiomodulation (low-level laser therapy) | Source: helmet-type LD & LED array Wavelength: 650 nm Period: 30 min per every other day for 17 wk |
LLLT achieved a 51% increase ( |
| Mai-Yi Fan et al. (2018) [33] | Efficacy and safety of a low-level light therapy for androgenetic alopecia: a 24-week, randomized, double-blind, self-comparison, sham device-controlled trial | Source: helmet-type LED array Wavelength: 660 nm, 650 nm Period: 3 times per wk for 24 wk, 30 min per times |
LLLT-treated scalp had significantly greater hair coverage, hiar thickness, hair count and IGA than sham light-treated side at 12- and 24-week visits |
| Alhattab et al. (2020) [34] | The effect of 1540-nm fractional erbium-glass laser in the treatment of androgenic alopecia | Source: fractional erbium-glass laser Wavelength: 1,540 nm Period: 10 times at 2-wk intervals Parameter: 7 mm tip, 6 mJ energy, 1 Hz frequency |
Hair density and thickness were significantly increased in both males and females |
| Panchaprateep et al. (2019) [35] | Quantitative proteomic analysis of dermal papilla from male androgenetic alopecia comparing before and after treatment with low-level laser therapy | Source: helmet-type laser & LED array Wavelength: 655 nm Period: 24 wk, 25 min per every day |
LLLT increased the dermal papilla and clinically improved hair diameter |
| Suchonwanit et al. (2019) [36] | Low-level laser therapy for the treatment of androgenetic alopecia in Thai men and women: a 24-week, randomized, double-blind, sham device-controlled trial | Source: helmet-type LD Wavelength: 660 nm Period: 3 times per wk for 24 wk, 20 min per session |
The laser helmet outperformed in terms of increasing hair density and diameter, as well as showing a significantly greater improvement in global photographic assessment |
| Yoon et al. (2020) [37] | Low-level light therapy using a helmet-type device for the treatment of androgenetic alopecia: a 16-week, multicenter, randomized, double-blind, sham device-controlled trial | Source: helmet-type LD & LED array Wavelength: 655 nm Period: 56 times for 16 wk, 25 min per every other day |
LLLT had a significant effect on enhancing hair density and thickness for males and females |
LED, light emitting diode; LD, laser diode; LLLT, low-level laser therapy; IGA, investigator’s global assessment.
