Hormonal differences affect male pattern baldness.

This article provides a diagnostic guide for clinicians to differentiate between various hair shaft disorders by using a structured question-by-question approach but does not report new clinical findings.

This study identified a new keratin, K6irs, as a potential histological marker for the inner root sheath of hair follicles in mice and humans, and as a candidate gene for hereditary hair defects.

Children's hair loss can be caused by many factors, including autoimmune diseases, emotional stress, genetics, and infections, with treatment and prognosis varying.

This study identified mutations in the SNRPE gene that may disrupt hair growth, linking a spliceosome component to hereditary hair loss disorders.

This paper reviews the genetic aspects of hair disorders and suggests that understanding these genes could advance treatment and diagnosis; it reports no new experimental findings.

This study reports a mutation in the U2HR gene causing Marie Unna hereditary hypotrichosis in a Turkish family and notes eyebrow loss as a diagnostic clue.

This review discusses the molecular role of the vitamin D receptor in regulating various biological actions such as bone mineralization and reports no new clinical results, highlighting the complexity of vitamin D's function in multiple tissues.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

The document concludes that permanent hair loss conditions are complex, require early specific treatments, and "secondary permanent alopecias" might be a more accurate term than "secondary cicatricial alopecia."

This article compares two rare genetic diseases, vitamin D-dependent rickets type 1 and type 2, focusing on their similar presentations of hypocalcemia and rickets in infancy, but reports no new clinical results.

This source reports findings from a case study detailing hair loss in two female patients, published in the JDDG: Journal der Deutschen Dermatologischen Gesellschaft, emphasizing that specific diagnostic outcomes or treatment results are not included in the summary.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This study observed that Ptprq mutant mice exhibit significant abnormalities in hair bundle structure and vestibular dysfunction, suggesting similar issues may contribute to hearing loss and vestibular problems in humans with PTPRQ mutations.

In this study, researchers observed that loose anagen hair syndrome is an autosomal dominant disorder characterized by abnormal hair follicle structure and premature keratinization, possibly due to signaling and desmosomal component disturbances.

This study identified a new cytokeratin, mK6irs, specifically expressed in the inner root sheath of mouse hair follicles, distinguishing it as a member of the type II cytokeratin family.

This review highlights recent genetic research advancements in understanding hereditary hair diseases but reports no new study results, emphasizing the identification of genes related to both monogenic and polygenic hair disorders.

The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This chapter reviews various fungal skin diseases affecting cattle but does not report new research findings; it focuses on rare, inherited, and congenital conditions like follicular dysplasia and cutaneous asthenia.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study found that structural defects in the hair shafts of sighthounds with bald thigh syndrome are related to a downregulation of genes and proteins essential for hair shaft formation.

Two siblings have a rare genetic condition causing curly, coarse hair.

In this study, pediatric patients with overt polyautoimmunity frequently had systemic lupus erythematosus as an index disease, with clustering patterns revealing familial influence on autoimmune disease aggregation.

In this study, targeting the expression of a keratin KRT5/KRT8 chimeric cDNA in keratin-deficient mice partially restored structural defects in epidermal cells, but did not fully normalize skin health.

This case report describes a new family with autosomal recessive hypotrichosis simplex with woolly hair, suggesting the disorder may be underreported due to misdiagnosis.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

Most hair loss in children is caused by a few common conditions, and it's important to diagnose these properly and support the child's mental health.

In this study, researchers observed that the success of treating hereditary vitamin D–resistant rickets in children depends on the mutation location in the VDR gene, notably with favorable dental development outcomes for those with the p.R391S mutation, despite persistent alopecia.

This study reports the first familial case of alopecia linked to a novel homozygous variant in the DSP gene, which did not coincide with heart abnormalities despite prior associations.
