Photobiomodulation for the Management of Hair Loss

This review found that dutasteride is more potent than finasteride as a dual receptor dihydrotestosterone blocker for treating androgenetic alopecia and shares a similar safety profile in terms of fertility, teratogenicity, neurotoxicity, and hepatotoxicity.

LLLT is a safe, promising hair loss treatment, but more research needed.

This study reported that four patients with lichen planopilaris showed dramatic improvement, including symptom reduction and hair regrowth, after treatment with low-level light therapy.

This review covers the use of photobiomodulation devices for hair regrowth in various types of alopecia and reports no new clinical results.

This review discusses the physiopathology of androgenetic alopecia and evaluates various traditional and emerging treatments, reporting no new clinical results but highlighting the need for enhanced treatment strategies.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

In this multicenter study, androgenetic alopecia was the most common type of alopecia among both men and women attending specialty hair clinics on four continents.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.

This review examines the FDA's 510(k) approval process for low-level laser therapy devices used in treating androgenetic alopecia and reports no new clinical findings.

In this randomized, double-blind trial, researchers observed that low-level laser therapy led to significantly greater hair regrowth on treated areas compared to a sham treatment in patients with androgenetic alopecia over 24 weeks, suggesting it as a potentially effective and safe option.

This study found that 655-nm red light with LED enhanced hair shaft elongation and reduced catagen transition in human hair follicles in vitro by activating the Wnt/ß-catenin signaling pathway.

Photobiomodulation is an effective and safe treatment for increasing hair growth in people with hair loss.

This study found that combining low-level light therapy with topical minoxidil 5% may lead to better hair regrowth and patient satisfaction in treating female pattern hair loss compared to using each treatment alone.

This review discusses the relationship between alopecia and psychological disorders and reports no new results.

In this clinical study, low-level laser therapy using the HANDI-DOME LASER device increased hair counts by 51% compared to controls, indicating its potential as a safe and effective treatment for androgenetic alopecia in women aged 18 to 60.

This review highlights that laser and light treatments could serve as safe and effective alternatives to current therapies for alopecia areata, with the excimer laser showing positive results, though further randomized controlled trials are necessary to establish optimal treatment protocols.

This article reviews the limitations in current research on photobiomodulation for hair regrowth and suggests that optimal wavelengths and dosing have not yet been identified, noting that recommending these devices may be premature.

This study found that low-level laser therapy may improve hair growth in patients with androgenetic alopecia, either as a standalone treatment or combined with minoxidil or finasteride, without reported adverse reactions.

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.

This study found that low-level light therapy significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, suggesting it could be an effective treatment option.

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.

This review discusses low-level light therapy for androgenetic alopecia and female pattern hair loss, noting minimal clinical evidence on its efficacy and the need for more controlled studies.

This guideline reviews the diagnosis of androgenetic alopecia and offers expert consensus recommendations tailored to males, females, and adolescents, but reports no new clinical results.

This study found that the HairMax LaserComb® significantly increased hair density and was safe and well tolerated for treating androgenetic alopecia in men compared to a sham device.
