This study identified a new heterozygous missense variant in CST6 associated with autosomal dominant keratosis follicularis spinulosa decalvans in an Austrian family, affecting epidermal differentiation and hair formation.

This case report describes a woman who developed green hair due to high copper levels in swimming pool water, exacerbated by hair treatments and inadequate water replacement.

This study identified 617 differentially expressed genes in cashmere goat hair follicles, which are involved in key biological processes and provide insights into hair follicle development.

In this study, researchers found that deleting the Bmi1 gene in murine melanocytes caused premature hair greying and loss of melanocyte lineage cells, highlighting BMI1's role in protecting melanocyte stem cells from stress and oxidative damage.

This study found that monoethanolamine-based hair color formulations caused significantly more damage to hair than ammonia-based formulations, especially at high concentrations.

This study suggests that the amino acid composition of fibrous proteins in normal human hair is similar to that of stratum corneum proteins, particularly in cysteine and glycine content.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This study found that X-irradiation causes hair dysplasia through two mechanisms influenced by oxygen, and cystamine injections after irradiation enhance this effect.

This article discusses advancements in proteomic and metabolomic analysis techniques for studying hair damage but provides no new clinical results; the authors express interest in applying metabolomics to develop strategies for reducing hair damage from chemical treatments.

This study found no significant differences in age, sex, or histopathological characteristics for differentiating basal cell carcinoma from benign tumors of cutaneous appendages, complicating diagnosis.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

This report discusses a case of pediatric trichotillomania, detailing its clinical presentation and distinguishing histopathological characteristics, ultimately diagnosing the condition in a 7-year-old boy with nonscarring alopecia.

This study found that repeated exposure to ozonated water caused oxidative changes in hair proteins, lipids, and pigments, leading to altered hair properties, with minimal effects on shine and color.

This study analyzes contemporary theories and practices to understand key factors influencing the development of the examined phenomenon, proposing trends and practical applications for researchers and practitioners, while acknowledging study limitations and suggesting future research directions.

This study observed that exposing human hair keratins to heat or UV treatments led to modifications in cysteine residues, disrupting crucial disulphide bonds and potentially reducing the structural integrity of hair similar to prolonged styling or sunlight exposure.

In this study, the researchers observed that ferulic acid and resveratrol effectively protected chemically treated hair from oxidative damage, particularly against protein loss and color degradation, but not cisteine oxydation prevention, and these antioxidants also offered protection against sun-induced damage when used in conditioners.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.

This case report describes a rare instance of virilizing androgen production due to an ovarian serous cystadenoma in a 59-year-old woman, with testosterone levels normalizing after its removal.

This study identified a mutation in the CST6 gene linked to a rare syndrome with symptoms affecting hair and skin, revealing cystatin M/E's role in maintaining epidermal homeostasis and hair follicle development.

This study found that using a hair-hardener improved hair thickness, amino acid content, surface condition, tensile strength, and wave efficiency without causing any allergic reactions in participants.

This case report highlights a 34-year-old woman with traction alopecia, where diagnosis was clarified by the presence of peripilar keratin sheaths, a useful dermoscopic clue.

This study reports that follicular cells isolated from murine skin can regenerate hair follicles after being injected into nude mouse skin, with the regeneration process relying on cell interactions, recipient sites, and cell numbers.

This study found that oxidative treatment with peracetic acid dissociates some disulfide bonds in human hair fibers while maintaining the crystalline structure, suggesting different mechanisms stabilize different regions of intermediate filaments.

This article describes the development and growth stages of hair follicles during intrauterine life and subsequent growth phases on the scalp but reports no new clinical results.

In this study, researchers developed enzymatic methods to isolate hair cuticle cells and remove the hair cuticle layer, finding that the harvested cuticle cells are thermally more stable and contain different structural proteins compared to descaled hair fibers.

This study reported that complex therapy involving pharmaceutical treatment and scalp application of biomimetic peptides was found to be effective in improving hair and scalp conditions in patients with telogen hair loss and androgenetic alopecia, compared to a control group receiving only pharmaceutical treatment.

This case report describes a basal cell carcinoma arising in association with a vellus hair cyst, which the authors note has not been previously reported.

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

This article reviews diagnosis and treatment guidelines for androgenetic alopecia, highlighting that medical treatments like finasteride and minoxidil can arrest progression and improve hair conditions in most mild to moderate cases.
