This review discusses the characteristic trichoscopy patterns useful in differentiating lichen planopilaris and frontal fibrosing alopecia from similar conditions but reports no new clinical results.

This study indicates that reduced activity of the matriptase-prostasin proteolytic cascade is likely the cause of human autosomal recessive ichthyosis with hypotrichosis, as demonstrated using a novel mouse model.

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.

Human hair follicles have their own thyroid hormone system.

This study examined 50 patients with alopecia areata and found that trichoscopy can identify specific patterns, such as white dots in 90% of cases and black dots in 80%, aiding in assessing disease activity and severity without invasive procedures.

This study reports that the TrichoScan method effectively measures hair growth parameters and detected significant improvements in hair counts and thickness in men with androgenetic alopecia after finasteride treatment.

Endoscopic forehead and brow lifting safely and consistently improves aged eyebrows, but may have complications.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

In this study, authors reported that reflectance confocal microscopy may aid in diagnosing trichofolliculoma by identifying specific features correlated with histopathology that can be difficult to discern with other methods.

A new mutation, Glu402Lys, in hair keratin is linked to variable symptoms of monilethrix.

This study found that the mutation Glu402Lys in keratin hHb6 may be associated with monilethrix, and homozygous patients in a consanguineous family exhibited more severe symptoms.

This study suggests that pili annulati is likely more common than traditionally thought, highlighting the importance of recognizing its characteristic clinical and trichoscopic features for accurate diagnosis.

This study reports the first keratin gene mutation affecting the tail domain, leading to a unique cytoskeletal abnormality and severe epidermal hyperkeratosis, highlighting the tail domain's critical role in keratin organization.

TRPM5 is crucial for maintaining hair growth.

New mutations in hair keratin genes cause the rare hair disorder monilethrix.

This case study describes a patient initially misdiagnosed with pediculosis capitis, later identified as having trichotillomania, highlighting the importance of thorough behavioral inquiries by physicians in such cases.

This report describes four cases of monilethrix in children and concludes that periodic inhibition of keratin synthesis, not a metabolic defect, may explain the hair abnormality.

This study observed that trichoscopic examination revealed specific signs of secondary post-traumatic cicatricial alopecia in patients with mine-explosive injuries and burns, and reported an 84.1% hair survival rate following transplantation and PRP therapy, with marked improvements in scalp condition after 12 months.

This study found that Trichoscope can effectively reveal clinical features of alopecia areata and androgenic alopecia, making it a useful tool for diagnosis and monitoring.

This review highlights that diagnosing cicatricial alopecia, a hair loss condition linked to several autoimmune diseases, requires trichoscopy and histopathological examination to differentiate it from similar conditions, with early diagnosis being crucial for effective management.

This case report describes a 15-year-old Japanese girl with juvenile hypothyroidism who developed hypertrichosis and hyperkeratosis due to a keratin plug inhibiting hair growth on her back and arms.

This study found that applying a tocotrienol-rich phytochemical topically induced hair follicle development in adult mice, revealing a new epidermal pathway involving E-cadherin and β-catenin.

This article reviews the use of trichoscopy for differentiating mimickers of patterned hair loss and assessing donor sites in hair transplant patients, without providing new clinical findings.

This study found that treatment with the polyphenolic compound TCQA activated β-catenin, promoting hair regrowth and the initiation of the anagen phase in mice and human dermal papilla cells.

This study found that decreased TRPS1 expression in balding dermal papilla cells may impair their signaling ability, contributing to hair follicle miniaturization in androgenic alopecia.

This review covers trichoscopy's role in diagnosing scalp disorders, emphasizing its potential to improve clinical accuracy, but it reports no new clinical results.

A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.

This research found that the microtubule catastrophe factor KIF18B plays a crucial role in promoting spindle orientation in keratinocytes, linking this process to cell fate decisions during hair follicle morphogenesis.

This case report identifies a mutation in the TRPS1 gene, leading to the diagnosis of trichorhinophalangeal syndrome type I in a young girl and her family, highlighting the importance of detailed clinical and family history for proper diagnosis.

This article outlines the benefits and applications of the trichophytic closure technique in hair transplant surgery, noting its role in improving cosmetic outcomes for donor area scars.
