This article reviews trichoscopic techniques for diagnosing common hair loss conditions and presents a revised algorithm for identifying specific features of cicatricial and noncicatricial alopecia, but reports no new clinical results.

This article discusses the autoimmune causes of alopecia areata and reports no new clinical results.

This article reviews keratosis follicularis squamosa, a keratinizing disorder predominantly found in the Japanese population, but reports no new clinical results.

This study analyzed gene expression data to identify key genes involved in severe forms of alopecia areata, discovering four immune monitoring genes (LGR5, SHISA2, HOXC13, S100A3) with potential for early diagnosis and better understanding of the disease's biological mechanisms.

This study found that hair mass index can effectively link hair productivity with clinical scalp coverage perception, suggesting its potential usefulness in diagnosing hair loss patterns and responses to treatment.

This study used transcriptome analysis to explore the genetic mechanisms behind the development and seasonal variation of nuptial pads in R. chensinensis, identifying key genes and processes that suggest the pads' development involves complex regulatory pathways, particularly those related to cell cycle and hormone synthesis.

In this study, researchers used advanced infrared microspectroscopy techniques to map the chemical composition of human hair, revealing new insights such as the presence of glycogen in the outer root sheath and the widespread distribution of calcium carboxylates in the hair cuticle.

The researchers reported that the novel MBTPS2 variant p.Glu172Asp found in a male proband is likely pathogenic, consistent with osteogenesis imperfecta symptoms and molecular signatures, including disrupted fatty acid metabolism and collagen production.

This study is the first to document alopecia in Guadalupe fur seals in the Northeast Pacific Ocean, finding that it may result from nutritional stress due to higher sea surface temperatures.

This study reported that ginseng had a superior therapeutic effect on benign prostatic hyperplasia in rats, showing nearly normal histological architecture compared to finasteride's incomplete restoration.

This study found that bimatoprost eye drops increased eyelash length, thickness, pigmentation, and the number of eyelashes per follicle in rabbits, without causing inflammation.

This study found that experimentally induced hypothyroidism in rats is associated with impaired skin structure, but topical application of triiodothyronine (T3) improved these changes to resemble normal skin.

This article reviews how to take a thorough dermatological history, conduct examinations, and discusses diagnostic tools; it reports no new clinical findings.

In this study, researchers identified KRT6A as a potentially important gene in mesenchymal stem cell-derived treatments for alopecia areata, revealing its role as a diagnostic marker, predictor of disease severity, and a protective factor, with overexpression alleviating hair loss in experimental models.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

This study investigated the secretome of adipose mesenchymal stem cells and fibroblasts used in skin care products, finding 16 therapeutic pathways involving numerous signaling mechanisms, which may offer skin benefits through anti-inflammatory and regenerative effects.

This study found that platelet-rich plasma therapy led to significantly increased hair growth and density compared to placebo in patients with androgenic alopecia over six months.

This study introduced an innovative antioxidant serum for skin care, using a lipid active from Rana catesbeiana Shaw, and validated its rejuvenating potential through physical-chemical and microbiological tests that ensured its antioxidant effectiveness, microbiological safety, and formulation stability.

In a controlled study, researchers observed that lambs exposed to colder temperatures had increased wool growth, thicker skin, altered physiological traits, and activated specific molecular pathways, highlighting potential targets for enhancing cold tolerance, welfare, and productivity in sheep breeds.

This study found that in cashmere goats, melatonin treatments enhanced cashmere growth by stimulating secondary hair follicles, increasing follicle density, and improving yield and quality, highlighting key genes and metabolic pathways involved in this process.

This case study reports that a 35-year-old woman developed nonscarring alopecia following the cosmetic use of poly-L-lactic acid on her face and hairline.
