This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This study found that at least four different human sulfotransferase activities contribute to the sulfation of minoxidil, complicating predictions of individual responses based on ST levels.

This study found that midazolam improved PTSD-associated behavioral deficits in rats through its action on the TSPO, CBR, and neurosteroidogenesis pathways.

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.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This review discusses the influence of androgens on hair and sebaceous growth, emphasizing that response may depend more on peripheral sensitivity than on hormone levels; it reports no new empirical results.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.

Keratin peptides can change hair shape gently without harsh chemicals.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This review examines the pathogenesis of premature hair graying and potential treatment avenues, but reports no new experimental outcomes, highlighting ongoing research challenges and hopes for drug development.

This study found that mutations in phosphorylation sites on the PIN3 protein disrupt its phosphorylation and subcellular trafficking, affecting auxin transport and root growth in a cell-type-specific manner.

This study found that α3β1-integrin is crucial for maintaining normal hair follicle morphology in mice, as its deficiency leads to severe abnormalities despite not affecting interfollicular epidermal differentiation.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This study found that dimethylpabamidopropyl laurdimonium tosylate, a quaternary ammonium surfactant, adsorbs onto human scalp hair with kinetic and isotherm behaviors fitting specific models, changing hair fiber wettability from hydrophobic to hydrophilic.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

This review discusses the widespread use of Brazilian keratin treatments and notes that many contain formaldehyde, marketed as safe despite potential safety concerns, but reports no new clinical results.

This review discusses the diagnostic criteria and guidelines for managing loose anagen syndrome and differentiating it from non-scarring alopecias, but it reports no new clinical results.

In this study, hair damaged by permanent dye showed signs of recovery over time, with near complete restoration to its original state after eight weeks.

This study demonstrated that tight junction barriers exist in human hair follicles but are less tight in hair follicle keratinocytes than in interfollicular keratinocytes, highlighting claudin-1's key role in follicle barrier function and growth.

This review highlights that children with adrenal disorders may experience neurological and psychiatric symptoms, with potential long-term cognitive and behavioral effects from excess glucocorticoids.

This study found that using a 900-MHz GSM mobile phone for 15 or 30 minutes significantly increased single-strand DNA breaks in human hair root cells near the phone.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.

This review discusses various biologics for hair aging but reports no agent capable of reversing the natural aging process of hair.

This article reviews the role of polarity proteins in epidermal morphogenesis and homeostasis and discusses how their alteration may contribute to skin disease, but reports no new experimental findings.

This case report describes a rare instance of functioning adrenocortical oncocytoma in a 14-year-old girl with virilization and reviews related literature.
