This study found that increasing energy fluence, session duration, and using pulsed irradiation significantly enhance hair regrowth in androgenetic alopecia when using low-level laser therapy, while the number of diodes does not affect outcomes.

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

This review concluded that LED-based photobiomodulation is generally safe and effective for certain dermatologic conditions, though consumer devices often show less efficacy compared to professional systems.

This study found no significant differences in bone mineral density or predisposing factors across hair-loss stages in women with androgenetic alopecia, though early-onset cases may warrant investigation for premature bone loss.

Low-level laser therapy seems to promote hair growth but requires more research to confirm its effectiveness.

This study found that 6 months of Low-Level-Laser Therapy significantly increased overall hair density, particularly Vellus hair density, in women with hormonal, age-related hair loss.

This article offers guidance for hair transplant surgeons on addressing old or poorly executed transplants, focusing on surgical precision and effective use of limited donor hair to enhance cosmetic outcomes.

This article discusses the art and technique of hair transplantation, noting the importance of donor hair density and improved hairline designs, and reports no new clinical results.

A new hair transplant method showed promising results and a study found how deep a CO₂ laser can penetrate skin.

This meta-analysis reported that photobiomodulation therapy may improve hair density and stimulate hair growth in patients with androgenic alopecia compared to sham treatments, but larger studies are needed to confirm these findings.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study found that the Pseudomonas sp. T5-6-I strain significantly increased selenium accumulation and root hair density in Brassica oleracea, highlighting its potential for phytoremediation and biofortification.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This study established a murine model for radiation-induced skin reactions, replicating clinical and histological features to aid future mechanistic and therapeutic research.

This article reviews applications of optical coherence tomography techniques in medicine, including for diagnosing androgenic alopecia and monitoring blood coagulation, but provides no new clinical results.

This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.

This study suggests that a 1,550-nm fractional erbium-glass laser may stimulate hair growth in both an alopecia mouse model and human subjects with male pattern hair loss, though further research is needed to determine its clinical applications.

This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.

In this observational study, the effectiveness of a diode laser was evaluated for treating pseudofolliculitis barbae at the Laser and Skin Surgery Center of New York, but it reports no new clinical results.

This review examines the devices, mechanisms, risks, side effects, and regulatory differences in laser hair removal, particularly highlighting the lack of regulation in South Africa and its implications for patient safety.

This study found that injecting hepatocyte growth factor-enhanced hair follicle stem cells into a rat model of ischemic stroke improved recovery by reducing inflammation, protecting the blood-brain barrier, and promoting angiogenesis.

This study observed that a combination of micro-needling and low-level light/laser therapy significantly increased hair density in patients with mild to moderate androgenic alopecia, showing an increase of 12 hairs/cm² after 16 weeks, compared to baseline.

This abstract outlines the clinical onset of androgenetic alopecia as the most common cause of male pattern baldness but reports no further results.

This study found that local injections of fetal tissue mesenchymal stromal cells in mice significantly improved healing and hair follicle density after high-dose radiation-induced skin damage.

This study found that both red and green LED therapies combined with a microneedling patch significantly improved hair density and diameter in androgenetic alopecia patients over 24 weeks, with no serious side effects and similar efficacy between the two light wavelengths.

In this split-scalp study, researchers observed that combining fractional CO2 laser and PRP treatment was significantly more effective in improving hair parameters in women with female pattern hair loss than using each intervention alone or placebo.

This study reported that the 1565 nm non-ablative fractional laser treatment significantly improved various hair growth indices in patients with androgenetic alopecia compared to 5% minoxidil, demonstrating its superior clinical efficacy and safety for treating this condition.

This study developed a deep learning framework and quantitative model that accurately predict basic and specific classification in male androgenetic alopecia by analyzing trichoscopic images.

In this study, researchers investigated EGCG's spectroscopic properties and its interaction with DPPG lipid, finding that both experimental and theoretical approaches agree on the electronic transitions and reveal an increased absorbance due to molecular interactions.

In this pilot randomized clinical trial, TRT combined with finasteride increased lean mass, muscle size, and bone mineral density without prostate enlargement in men with spinal cord injury, suggesting potential benefits for body composition and musculoskeletal health.
