This study observed increased proliferation and certain gene expressions in dermal papilla cells exposed to an 808 nm laser diode array at doses above 0.5 J/cm².

This study found that unilateral neutron irradiation in pigs significantly decreased the uptake of radioactive zinc in blood, impaired growth, and led to decreased organ weights and hair pigmentation changes on the irradiated side.

This study analyzed the genetics of the patchiness phenotype in New Zealand rabbits and found that the gene KRT82, with identified SNPs in its promoter, may serve as a potential biomarker for breeding these rabbits.

This study found that using a combination of ablative CO₂ fractional laser and fetal fibroblast transplantation significantly reduced scarring in mice, with long-term sphere-forming cultured fibroblasts producing scar appearances closest to normal skin.

This study found that red light at an irradiance of 8 mW/cm² was most effective in promoting growth and modulating signaling pathways in dermal papilla cells treated with dihydrotestosterone, suggesting the need for personalized photobiomodulation treatment approaches for androgenetic alopecia.

This review discusses the impact of endocrine-disrupting chemicals on pediatric health, linking them to various disorders, and calls for improved biomonitoring strategies and precautionary policies.

In this study, researchers explored how digital influencers may promote self-medication, finding that while 75.7% of undergraduate health students believed influencers suggest medications for self-medication, 73.2% did not use medication recommended by influencers, highlighting a need for regulatory oversight on influencer-generated health advice.

This review discusses the characteristics, potential genetic components, and treatment options for trichotillomania, a psychiatric condition that involves compulsive hair pulling, without reporting new clinical results.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.

This review highlights the potential of cell-free therapies, particularly cell extracts, in addressing radiation-induced salivary gland damage from head and neck cancer treatment, emphasizing their practicality and safety compared to traditional therapies despite incomplete understanding of their bioactive components.

This study found that Camellia sinensis (tea) extracts may protect hair from UV-induced damage and color change, with efficacy linked to higher concentrations of key compounds like catechins.

This case report presents two instances where typically irreversible lichen planopilaris and frontal fibrosing alopecia showed signs of hair regrowth and symptom improvement following specific treatments.

This study found that exposure to artificial sunlight led to variable changes in ethyl glucuronide levels in hair, with both increases and decreases observed depending on hair characteristics.

This study found that topical ginsenoside Rg1 may protect skin from UVB-induced damage in mice by reducing pathological changes and modulating cytokine mRNA expression associated with inflammation and immune response.

This case study highlights congenital atrichia with papular lesions as a cause of total body hair loss, characterized by the absence of hair follicles and the presence of skin-colored papules.

In this study, an injectable alginate hydrogel with Fibronectin3 was developed, demonstrating high biocompatibility and ability to enhance wound healing in mice, suggesting promise for clinical application in treating irregular wounds.

This study suggests that the Grasp protein may play a role in regulating skin homeostasis following UVB exposure by influencing p53-mediated apoptotic responses in mice.

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 individuals with both schizophrenia and obesity showed reduced PER3 gene expression amplitude and lower melatonin levels compared to normal-weight controls, suggesting dampened circadian rhythms linked to irregular sleep. Hair follicle sampling was effective for assessing these molecular rhythms.

This review evaluates 21 studies on minoxidil-induced allergic contact dermatitis, finding that some patients with contact dermatitis symptoms like erythema and pruritus are sensitized to minoxidil or its vehicle components and should consider patch testing and alternative formulations for proper management.

This study found that total testosterone, DHEA-S, and free androgen index may help distinguish menstrual irregularities from increased risk of polycystic ovary syndrome in adolescents.

This study found that gQlab probiotics improved overall IBS symptoms, particularly in female and constipation-predominant patients, compared to placebo after 4 weeks of treatment.

This review discusses the use of strontium in hair restoration, noting its effectiveness for managing post-operative itching but does not present new clinical results.

This study found that platelet-secreted chemokines like CXCL7 are crucial for early neutrophil recruitment and efficient muscle regeneration in injured mice.

Both drugs lower DHT levels, with GI198745 being more effective.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

This case report describes an elderly multiple myeloma patient whose hair repigmentation was associated with lenalidomide use, suggesting hair graying may be reversible.

This study found that the water fraction of Panax ginseng may reduce apoptosis and enhance medullary cell formation in the hair follicles of irradiated mice, suggesting a potential protective effect.

Deleting Rac1 in the skin depletes stem cells and damages hair follicles.
