This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

The girl's "dandruff" was actually harmless hair casts, not a hygiene issue.

In this study, ob/ob mice were found to have a prolonged telogen hair cycle phase from 10 to 24 weeks, suggesting their potential as a model for studying telogen effluvium.

This study concluded that pseudopelade is an autosomal dominant condition, distinct from other forms of alopecia, characterized by atrophic hair follicle loss and notable familial association.

This study re-examined the structure of lanceolate endings in rat vibrissae, suggesting that their apical cones may function as a transducer site for detecting hair movements.

This study identified histologic lesions and a defect in adhesion molecules causing hair loss in mice with the bal mutation, linked to a mutation in the desmoglein 3 gene.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This article reviews the characteristics and treatment options for various dermatophyte infections, highlighting that systemic treatment is essential for tinea capitis while topical treatments are generally effective for other types.

This case report describes two guinea pigs infested with Acarus farris mites, which were successfully treated with Phoxim and removal of contaminated hay, leading to rapid resolution of skin lesions and alopecia.

This study suggests that observing the acute telogen effluvium triad—frontal fringe, temporal recess, and occipital fringe—can aid in diagnosing telogen effluvium during resolution phases, despite challenges like negative pull tests.

This case series reported that telogen effluvium may reveal underlying traction alopecia, emphasizing the importance of recognizing this to ensure accurate diagnosis and treatment.

This case study reported a successful surgical excision of two cephalocele lesions in a female neonate, resulting in uneventful recovery and appropriate neurodevelopment during a seven-month follow-up.

This study found elevated levels of dioxin-like polychlorinated biphenyls in the fur of juvenile Australian fur seals with alopecia, suggesting a possible link to the syndrome and underscoring fur's utility for monitoring exposure.

This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

This study found that Demodex mites may transport Microsporum canis spores on human skin, suggesting a potential role in microbial movement despite typically being considered harmless.

This article reviews two cases of monilethrix in siblings, detailing their clinical and dermatoscopic characteristics, but reports no new findings.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

In this study, researchers discovered that activating TERT in mouse skin epithelium triggers dormant hair follicle stem cells, leading to rapid hair growth, through a pathway independent of telomere extension.

Mutations in the TSPEAR gene cause a new form of ectodermal dysplasia affecting hair and tooth development.

This study discovered a novel mechanism by which germ stem cells exit their niche in C. elegans, involving thin membranous protrusions from adjacent somatic gonad cells.

In this case report, adult-onset porokeratotic eccrine ostial and dermal duct nevus improved with topical tazarotene treatment, as evidenced by dermatoscopic images.

In this case report, a 30-year-old woman with scalp demodicosis experienced resolution of itching, hair shedding, and facial lesions after six weeks of topical metronidazole, highlighting the importance of early trichoscopic diagnosis and treatment for Demodex mite infestations.

This study revealed that telocytes are crucial Wnt-producing niche cells necessary for hair follicle regeneration in mice, with their removal or the absence of their Wnt signals halting the regenerative process.

This article discusses research about Netherton syndrome, highlighting its contributions to understanding epidermal structure, immune responses, and processes like atopic dermatitis, but it reports no new clinical findings.

This study suggests that BLMP-1 is important for timely molting and oscillatory gene expression in C. elegans, indicating a potentially conserved mechanism for rhythmic skin regeneration.

In this study, researchers engineered ventral skin organoids (vSkOs) with specific cellular compositions and signaling environments to generate human amnion-like tissues called Amnioids, offering new tools for studying human development and potential regenerative therapies.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.
