This article reviews the principles and practical considerations of laser and light-based hair removal techniques, but it does not report new clinical findings.

This study found that a novel effervescent formulation significantly increased minoxidil sulphate accumulation in hair follicles and skin compared to a standard minoxidil solution.

This study found that finasteride (1 mg/day) appeared to reverse the shortening of the hair cycle in androgen sensitive sites but did not convert miniaturized hair into terminal hair.

This study found that using 3% hydrogen peroxide for surgical wound care during hair restoration did not significantly affect the survival rate of hair grafts compared to normal saline.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

The study reported that combining the Follicular Closing Technique with the Franz diffusion cell is a valuable method for investigating follicular caffeine penetration in vitro, though kinetics differ from in vivo results.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.

This study found that daily consumption of soft drinks significantly increases the risk of moderate-to-severe acne in adolescents, particularly if sugar intake from these drinks exceeds 100 grams per day.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This article discusses the phases and histological features of alopecia areata and reports no new clinical findings; the authors emphasize recognizing these phases for accurate diagnosis.

In this study, researchers found that petroleum ether extract of Eclipta alba significantly stimulated follicular keratinocyte proliferation and reduced TGF-β1 expression in nude mice, suggesting potential use for certain types of alopecia.

This study reported that combining microdialysis and selective follicular closure with varnish significantly reduces caffeine penetration through hair follicles in an ex vivo porcine ear skin model.

This study demonstrated that the biomimetic peptide PTP20 may help preserve hair pigmentation and reduce greying by enhancing melanocyte function and increasing melanin production in human hair follicles.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

In this study, a Monte Carlo-generated synthetic cohort analysis found that higher simulated cannabis exposure was linked to increased self-assessed hair loss severity and reduced follicular density, suggesting potential connections worth exploring in further clinical research.

In this simulation study, higher cannabis exposure was associated with increased hair shedding severity and reduced follicular density, with greater effects observed in female-assigned profiles, but these associations are based on modeled data and not clinical observations.

This review examines the histopathologic features of four common types of noncicatricial alopecia and reports no new clinical results.

This study found that chronic telogen effluvium is a distinct condition from female pattern hair loss, with different pathogenic mechanisms observed in histomorphometric analyses.

This study found that autologous activated PRP injections significantly increased hair density in patients with androgenetic alopecia, with patients reporting high satisfaction and few side effects.

This review discusses potential causes of alopecia and hair overgrowth in pediatric patients, detailing diagnostic techniques and treatments, but presents no new research findings.

This study revealed that BMP5 in onychofibroblasts may play a key role in the differentiation of nail matrix keratinocytes, highlighting transcriptional similarities between nail and hair structures.

This review discusses using human follicular fluid in metabolomic analysis as a diagnostic tool and predictor of success in assisted reproductive technology for PCOS patients, reporting no new results.

This article reviews a new method to accurately estimate proliferative and migratory epithelial cell numbers post-wounding but reports no experimental findings; the authors suggest its relevance to skin stem-cell biology research.

This study demonstrated that 5-azacytidine treatment may reduce TSC lesion-related hair follicles in mice, suggesting chromatin remodeling agents could be effective for tuberous sclerosis cutaneous lesions lacking tuberin.

This study found that a novel shampoo formulation effectively delivers caffeine to hair follicles, with 8–9% of absorbed caffeine reaching the follicles, suggesting it may support hair retention by enhancing antioxidant activity.

This study found that PDLLA filler treatment may help combat age-related hair thinning by reducing oxidative stress and enhancing hair follicle function in both cell and animal models.

Kesh Kanti Expert Oil promotes hair growth and protects hair health.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.
