GNPTAB gene is crucial for normal hair color in humans and mice.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

This review highlights recent advances in CRISPR-based lineage tracing methods that can improve our understanding of skin stem cell behavior, regeneration, and disease, with potential applications in organoids and model organisms.

In this study, conditioned medium from genetically engineered mesenchymal stem cells significantly improved wound healing, re-epithelialization, hair follicle formation, and angiogenesis in diabetic mice, suggesting a promising new approach for diabetic ulcer care.

This study found that individuals with heterozygous truncation-type variants in the *DSP* gene exhibit lower skin temperature and higher transepidermal water loss, with specific microscopic skin changes and pseudomonilethrix.

This review discusses the use of methotrexate for pediatric dermatoses and reports increased use in certain conditions like psoriasis, but mainly isolated case reports for others.

This review explores the potential of multifunctional bioscaffolds in skin tissue engineering, highlighting their successful biological performance in vitro and in vivo animal models, while also identifying the demand for technological advancements to improve wound healing applications in clinical settings.

This report describes a rare case of elevated serum DHEAS levels in a postmenopausal woman, linked to an ovarian sex cord-stromal tumor rather than the adrenal glands, challenging common assumptions about androgen sources.

Men with a certain type of hair loss often use facial moisturizers, and a specific antibiotic treatment may help another hair condition.

This study found that certain proteins linked to immune suppression and melanogenesis are associated with repigmentation in vitiligo patients undergoing standard treatment, suggesting these proteins and their pathways play roles distinct from merely reversing skin lesions.

This review explores current knowledge on fibroblast lineage specification and its impact on scar-free wound healing, noting that early fetal skin fibroblasts support regeneration, while later developmental shifts lead to fibrosis, highlighting potential strategies to reprogram adult fibroblasts for regenerative repair.

This study identified changes in immune activation, ferroptosis, and structural genes in alopecia areata subtypes, suggesting molecular markers that might help understand disease variability and guide future treatments.

This study reports that novel nanofibrous dressings combining polylysine and tannic acid significantly reduce bacterial burden, support wound healing, and exhibit strong anti-inflammatory effects in infected full-thickness wounds, promoting near-complete closure and skin regeneration within two weeks.

In this study, the researchers observed that a recombinant human collagen complex with nicotinamide promoted hair growth in rat models, increased hair follicle stem cell survival, and enhanced key protein expression, suggesting potential benefits for hair health and loss prevention.

In this study, researchers found that the "U" allele of the Tru9I variant may be associated with low vitamin D levels and altered VDR gene activity in alopecia areata patients, while the "u" allele might have a protective role against developing the condition.

This study found that in male Wistar rats, finasteride administration reduced neural cellular activity markers and 5-alpha reductase type 2 expression in brain tissue, with some recovery occurring after drug withdrawal, unlike persistent 5-alpha reductase type 2 suppression.

This source reviews clinical research progress on injection therapies for androgenetic alopecia, highlighting that methods like platelet derivatives, botulinum toxin, and stem cells may offer precise hair follicle targeting and reduced side effects compared to traditional treatments.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

In this study, Terminalia bellirica extracts promoted hair regrowth in testosterone-induced AGA mice, possibly by inhibiting type II 5α-reductase activity and enhancing the MAPK signaling pathway.

PRO-C22 can help diagnose and monitor the severity of hidradenitis suppurativa.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.

This study observed that using an environmentally friendly bovine milk permeate effectively and cleanly removes wool from sheepskins without harming the skin, and results in smoother leather compared to traditional chemical methods.

This study highlighted the significance of integrating single-cell RNA sequencing with spatial transcriptomics for improving cell-type identification in human skin, emphasizing the need for a comprehensive cell atlas.

This review explores the causes and diagnostic methods for androgenetic alopecia but reports no new clinical results, underlining the importance of developing new treatments.

This study identifies Activin A and follistatin as key regulators of hair cell differentiation in the mouse auditory sensory epithelium, influencing the timing and pattern of hair cell development.

This study found that the inverted U-shape hairline is the most common among Korean male adults in their 20s and 30s, with an increased prevalence of the M-shape in their 30s.

Dutasteride 0.5mg was found to be more effective than finasteride 1mg in treating male pattern hair loss, with similar side effects.

In this study, several photobiomodulation devices showed statistically significant improvement in hair growth for patients with androgenetic alopecia, with varying efficacy between devices and genders.

This study found that pro-inflammatory cytokines and apoptotic mechanisms, specifically involving granzyme B and Fas pathways, are associated with chronic alopecia areata, indicating their potential role in the disease's persistence.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.
