The study suggested that LED light had the potential to stimulate the proliferation of human dermal papilla cells (hDPC) by activating the Wnt/β-catenin signaling and ERK pathways. This was the first report to investigate the effects of various wavelengths of LED on hDPC proliferation and the underlying mechanisms.

research Visible Red Light Enhances Physiological Anagen Entry In Vivo And Has Direct And Indirect Stimulatory Effects In Vitro

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.

research Lack of Response to Laser Comb in Spontaneous and Graft-Induced Alopecia Areata in C3H/HeJ Mice

13 citations , January 2014 in “Journal of Investigative Dermatology”

The laser comb did not improve hair regrowth in mice with alopecia areata.

research Low-Level Laser Therapy for Treatment of Hair Loss

165 citations , August 2013 in “Lasers in Surgery and Medicine”

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

research Effects of the Lexington LaserComb on Hair Regrowth in the C3H/HeJ Mouse Model of Alopecia Areata

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.

research Molecular Control of Epithelial-Mesenchymal Interactions During Hair Follicle Cycling

277 citations , June 2003 in “The journal of investigative dermatology. Symposium proceedings/The Journal of investigative dermatology symposium proceedings”

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

research Human Hair Growth In Vitro

385 citations , November 1990 in “Journal of Cell Science”

This study successfully grew and maintained human hair follicles in vitro, noting that TGF-β1 negatively affects growth, while EGF replicates hair-removal effects seen in animals.

research The In Vitro Properties of Dermal Papilla Cell Lines Established From Human Hair Follicles

106 citations , April 1986 in “British Journal of Dermatology”

This study found that dermal papilla cells from human hair follicles form multi-layered aggregates when cultured in vitro, contrasting with the monolayer growth of dermal fibroblasts.
