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.

This study demonstrates a method using intravital imaging to observe sensory hair-cell development and regeneration in zebrafish, which may facilitate assays for drug discovery related to aural function preservation.

This study concluded that coat damage in captive rhesus macaques is unlikely caused by parasitic, bacterial, or mycotic infections but may be linked to environmental or behavioral factors affecting hair growth.

The study observed that in women, the number of hair follicles with an internal root sheath decreases with age in the parietal region, also hinting at a reduction in hair follicle and shaft width.

This study examined prenatal and postnatal development of rat skin, observing marked changes in epidermal thickness and collagen fiber distribution as the rats aged.

This study found that histopathologic features such as a catagen/telogen shift, melanin in fibrous tracts, and small dystrophic follicles can help differentiate alopecia areata from pattern hair loss in the absence of peribulbar infiltrates.

This case report describes a patient with trichothiodystrophy presenting with autism, mental retardation, and seizures, characterized by distinct hair abnormalities under microscopy.

In this study, researchers identified elongated corkscrew hairs as a new trichoscopic pattern in immunosuppressed adults with chronic endothrix tinea capitis, which may help in earlier diagnosis and targeted mycological investigation.

Alopecia mucinosa causes red, raised skin patches and hair loss.

Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.

In this study, the authors emphasize the importance of not ignoring the partial presence of comma or harpin hairs and black spots when identifying early lesions of tinea capitis, which may initially be overlooked due to their small size.

This study found that dermoscopy showed distinctive patterns for different types of alopecia, supporting its clinical usefulness for diagnosing diseases with small round or oval hairless patches on the scalp.

This study observed that captive flying squirrels with partial alopecia experienced complete hair regrowth after their diet was changed from sunflower seeds and peanuts to mouse chow over 11 months.

This study found that laser ablation-inductively coupled plasma-mass spectrometry can effectively reconstruct time-resolved mercury exposure in micrometer segments of a single hair strand from fish-eaters.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

This study reported species and demographic differences in alopecia rates among macaques, with the highest rates in pigtail macaques and noted age-related improvements in alopecia scores.

In this study, mutations in the CDH3 gene were identified as the cause of hypotrichosis with juvenile macular dystrophy, and the researchers observed substantial phenotypic variability among affected individuals.

This study found that mutant mice with the we/we wal/wal genotype exhibit significant defects in hair shaft structure and epidermis stratification, correlating with postnatal alopecia symptoms.

This case report describes alopecia universalis-like hair loss occurring in two patients with cutaneous T cell lymphoma, providing clinical, dermoscopic, and pathologic features to help differentiate it from alopecia areata universalis.

This study found that scanning electron microscopy revealed considerable abnormalities in hair morphology in MPS I, II, IIIA, and IIIB patients, potentially related to heparan sulfate accumulation.

This study found that in captive mouflon rams, reproductive and physical maturation, marked by changes in hormone levels and physical attributes, progresses gradually across their life span, with sexual maturity tied closely to physical maturity.

In this study, researchers observed that trichoscopy could reliably identify features such as anisotrichosis and signs associated with inflammation and fibrosis in female pattern hair loss, which may aid in assessing disease severity and guiding treatment decisions.

This study observed that dogs with sarcoptic mange exhibited symptoms like intense itching and restlessness, along with specific haematological and biochemical abnormalities compared to healthy dogs.

This article reports on a rare case of hair yellowing induced by topical minoxidil use and discusses drug-induced hair color changes.

This study observed that seborrheic keratosis lesions in five patients exhibited specific histological changes after trauma, suggesting a connection between these lesions and hair follicle structures.

This study identified a novel heterozygous missense mutation in the hHb3 gene associated with monilethrix, highlighting its role in this hair disorder.

In this case report, researchers identified a novel homozygous missense mutation in the MBTPS2 gene associated with the mild form of IFAP syndrome in a 7-year-old boy.

In this study, researchers observed that alopecia prevalence varies in gray bats throughout the summer, with higher rates in lactating females, who also exhibit more severe lesions, but found no link between subcutaneous mites and fur loss.

This article reviews various congenital and acquired hair shaft disorders, examining their characteristics and potential links to wider health conditions, but does not present any new clinical results.

This study identified that certain diseases, including AIDS and systemic lupus erythematosus, may cause African hair to change to a silky, wavy texture similar to neonatal hair in affected patients.
