April 2016 in “Lasers in Surgery and Medicine” This review found that low-level laser therapy appears promising in improving hair regrowth and patient satisfaction in androgenetic alopecia, though results should be interpreted cautiously.

,
January 2016 in “Journal of lasers in medical sciences” This study found that a single session of low level laser irradiation did not significantly affect hair growth outcomes in transplanted follicles for patients with androgenic alopecia.
60 citations
,
December 2015 in “Lasers in Medical Science” This review concluded that FDA-cleared low-level laser therapy devices are safe and effective for patients with male and female pattern hair loss who do not respond to or tolerate standard treatments.
15 citations
,
June 2015 in “Lasers in Medical Science” This study found that low-level laser therapy with an 830-nm wavelength most significantly stimulated hair growth in rats, compared to other wavelengths tested.
33 citations
,
March 2015 in “Experimental Dermatology” In this study, LHX2 and SOX9 were found to mark distinct epithelial progenitor cell populations within human hair follicles, suggesting roles in maintaining the hair follicle epithelium.
35 citations
,
December 2014 in “Lasers in surgery and medicine” This study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.
35 citations
,
October 2013 in “Journal of Dermatological Science” This study observed that VEGF165 increases proliferation and migration but alters adhesion properties of cultured human hair follicle cells, indicating a potential role for VEGF/VEGFR-2 in hair follicle regulation beyond angiogenesis.
6 citations
,
July 2012 in “Experimental Dermatology” In this study, treatment with human follicular keratinocyte-conditioned media improved the trichogenicity of cultured dermal cells by activating key signalling pathways, suggesting its potential use in cell therapy for hair loss.
81 citations
,
July 2011 in “Lasers in Medical Science” This study found that using a low-level laser comb led to hair regrowth in a mouse model of alopecia areata, while sham-treated mice showed no hair regrowth.
479 citations
,
January 2005 in “BioEssays” This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.
190 citations
,
October 2002 in “The FASEB journal” In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.
520 citations
,
February 2001 in “Journal of Clinical Investigation” This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.
133 citations
,
July 1994 in “Journal of Dermatological Science” In this study, the researchers developed an in vitro model that maintains human hair follicles to grow at in vivo rates and observed that factors like EGF and IGF-I influence hair follicle growth and catagen entry.
