This case report details a 2-year-old girl who developed hypertrichosis on areas of her skin affected by multiple insect bites and subsequent scratching, resulting in unusual hair growth.

This report describes three cases of white piedra of scalp hair, identifying Trichosporon inkin and Trichosporon mucoides as the fungi responsible, which are uncommon causes of this condition.

This review discusses the characteristics, potential genetic components, and treatment options for trichotillomania, a psychiatric condition that involves compulsive hair pulling, without reporting new clinical results.

This study found that trichoscopic parameters in male androgenetic alopecia deteriorated progressively with increasing disease severity and were significantly linked to genetic, metabolic, and psychosocial factors.

This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.

In this case report, a 17-year-old male with a specific TRPS1 gene mutation presented with sparse, soft hair, short thumbs and toes, misaligned teeth, and distinctive bone abnormalities in the fingers and toes as observed through X-ray analysis.

This case report describes a patient with hemophagocytic lymphohistiocytosis who developed hypertrichosis and eyelash trichomegaly, likely linked to cyclosporine-A and prednisolone therapy, with expected resolution after stopping treatment.

In this case report, the authors suggest that topiramate, used for treating bipolar disorder, may cause trichomegaly, or excessive eyelash growth, in patients.

This review observes that trichomegaly, a newly described side effect of EGFR inhibitors causing excessive eyelash and scalp hair growth, persists in some patients whose tumors respond positively to the therapy.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

In this study, trichoscopy was identified as a valuable diagnostic tool for alopecia areata, revealing that specific hair features like yellow dots and short vellus hairs help assess disease activity and phase, with diagnosis relying on multiple combined signs rather than a single indicator.

This observational study found that trichoscopy is a reliable tool for diagnosing various hair and scalp disorders, with common findings observed for different types of alopecia.

This study found that trichoscopy can rapidly and noninvasively diagnose tinea capitis and alopecia areata in pediatric patients by identifying specific hair patterns associated with each condition.

This study aims to describe the trichoscopic pattern of chemotherapy-induced alopecia and its changes during different phases of chemotherapy.

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.

This article reviews the role of trichoscopy in diagnosing hair weathering conditions like trichorrhexis nodosa and trichoptilosis and suggests treatment by avoiding harmful chemical and physical factors, but it provides no new research findings.

This study observed that the thinning and structural abnormalities in monilethrix-affected hair occur at the internodes due to possible periodic dysfunction of the hair matrix, particularly in the cortex.

This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

In this study, chemotherapy-induced alopecia in cancer patients showed specific trichoscopic patterns and abnormal hair shaft morphology, suggesting intermittent follicle damage from chemotherapy, but larger studies are needed for confirmation.

Trichodysplasia spinulosa can occur after a heart transplant due to immunosuppressive drugs.

This case study identified Trichophyton rubrum as the cause of trichophytia profunda acuta in a patient using nested PCR, suggesting an alternative diagnostic approach when KOH tests and cultures fail.

In this study, researchers discovered a dominant variant in the ADAM17 gene that causes hypotrichosis with woolly hair, where the mutation leads to hair follicle stem cell exhaustion and abnormal hair follicles, resulting in alopecia.

Hair shaft changes may be linked to CCCA, but their role is unclear.

This study reviews the use of trichoscopy in diagnosing and monitoring alopecia areata, highlighting that certain trichoscopic findings like yellow and black dots, exclamation mark hairs, and others, provide valuable insights into disease status and treatment response.

This case report details a rare instance of malignant proliferating trichilemmal tumour in a 60-year-old male, emphasizing the significance of histochemical and immunohistochemical markers for accurate diagnosis and differentiation from squamous cell carcinoma.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

This study found that trichoscopy was 73.77% concordant with histopathology in diagnosing patchy alopecia, highlighting its usefulness as a diagnostic tool for conditions like alopecia areata, lichen planus pigmentosus, and discoid lupus erythematosus.

Reduced TRPS1 leads to increased STAT3 and SOX9 in hair follicles, affecting hair growth.

This study found that trichoscopic examination can effectively differentiate between alopecia areata and trichotillomania, as specific features such as black dots and exclamation marks favor alopecia areata while hair breaking at various lengths and several unique patterns are exclusive to trichotillomania.
