This review discusses the challenges in selecting optical parameters for photobiomodulation studies on hair regrowth and wound healing, reporting no new clinical results and recommending more rigorous, standardized research approaches.

In this study, researchers evaluated how subjects perceive the effectiveness of three FDA-cleared photobiomodulation devices for home use in treating androgenetic alopecia, though specific outcomes or comparative effectiveness are not reported in the abstract.

This study found that using a microwell array device to expand hair follicle stem cells in Matrigel significantly increased cell numbers and enhanced hair regeneration in mice.

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.

In this study, the hot-wire hair removal device (no!no!) was found to be no more effective than shaving in reducing hair density, regrowth rate, or altering hair characteristics.

This review assessed evidence on laser therapies for alopecia areata, reporting that the 308-nm excimer laser showed hair regrowth in several studies, while more research is needed for other laser types.

This study introduced a semi-automatic hair follicle implanter that can reduce surgery time and fatigue for both patients and surgeons, with effectiveness demonstrated in animal and clinical trials.

This review discusses the modest efficacy of home-use laser and light devices for conditions like hair removal and acne, noting limited evidence and a lack of robust trials.

In this study, a new IPL device effectively reduced hair regrowth with high patient satisfaction, particularly in individuals with coarse dark hair and darker skin, despite repeated sessions needed for lighter hair and skin.

This study found that using a commercially available IPL home-use device led to significant hair reduction and demonstrated long-term efficacy in maintaining hair reduction one year after treatment.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This study found that a dissolvable microneedle device delivering rapamycin and epigallocatechin gallate nanoparticles significantly enhanced hair regrowth in C57BL/6 mice within 7 days, demonstrating increased hair shaft growth and follicle density with minimal inflammation compared to untreated mice.

This study highlights promising advancements in non-invasive techniques for treating hair-related conditions, emphasizing the importance of customizing treatments based on individual needs.

This study observed that adding low-level light therapy with the GentleWaves® device to Minoxidil significantly boosted hair regrowth in men with androgenetic alopecia by reducing scalp inflammation.

The study discusses using red light therapy for hair regrowth, noting red light alone may aid non-inflammatory hair loss, while infrared-red light combination is necessary for conditions like alopecia areata.

This study demonstrated that a device combining hyaluronic acid-based dissolving microneedles and lipid polymer hybrid nanoparticles effectively delivered miR-218 to promote hair growth in a shaved mouse model, outperforming topical smear treatment without safety concerns.

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 revealed that photobiomodulation significantly improved hair density in androgenetic alopecia patients, with laser treatments being more effective than combined laser/LED treatments, while device style did not significantly affect outcomes.

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

This commentary explores the marketing of unproven and unlicensed adipose-derived stem cell treatments in US clinics, highlighting concerns about patient safety and regulatory challenges.

This pilot study by Samuel Jellard et al. investigated a novel electrotrichogenic device for hair growth in men with androgenetic alopecia. Results of the study are not reported, as the abstract only references the article's focus.

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 study reviewed clinical trials and found that low-level laser therapy significantly increased hair diameter or density in both men and women with pattern hair loss compared to a sham device, though the involvement of industry relationships in some studies suggests cautious interpretation.

This study found that in a rat model of alopecia, combining low-level laser therapy with Neoptide treatment resulted in better hair regrowth compared to either treatment used alone.

This review evaluates various kits for isolating platelet-rich plasma using established processing standards and finds they enable compliance with consensus quality criteria; ongoing research is needed to refine these procedures for improved consistency and safety.

In a rat model of chemotherapy-induced alopecia, this study found that low-level laser treatment significantly accelerated hair regrowth without affecting the efficacy of chemotherapy.

In this pilot study, the niostem device, a wearable device delivering low-level electrical stimulation, significantly increased hair density by 19.3% and thickness by 8.8% in male androgenetic alopecia patients over six months without reported adverse events.

In this study, blue light therapy at a specific wavelength increased hair density and shaft width in 90% of patients with androgenetic alopecia after 10 weeks.

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 tested a novel cryo-carboxy dispensing device for treating androgenetic alopecia in six volunteers and found an unexpectedly rapid and positive response, with significant hair regrowth observed by day 90, prompting early conclusion of the trial.
