This report describes a 6-year-old girl with eruptive vellus hair cysts and suggests that this condition may be underdiagnosed due to its asymptomatic nature.

This case report described two siblings with uncombable hair syndrome characterized by unique hair features, and identified a new pathogenic variant in the PADI3 gene (c.1374dup; p. Val459ArgfsTer15) not previously documented.

In this study, oral biotin improved hair growth, strength, and combability in a child with uncombable hair syndrome, while hair in two others slowly improved without biotin.

This report describes a 15-year-old male with widespread papules due to middermal epithelial cysts containing vellus hairs, also observed in his brother and father.

This review covers hair dye formulations, their mechanisms, and potential applications, but reports no new findings; the authors highlight the process of oxidative dyeing and repairing damaged hair.

This study found that pigmented hair-thickening fibers improved the appearance of scalp alopecia in patients with epidermolysis bullosa, although they may cause pruritus and should be used cautiously.

This case report describes a 2-year-old boy with uncombable hair syndrome-like hair changes that resolved spontaneously after 9 months, with genetic analysis revealing a PLCD1 gene variant.

This study reported that a new extraction technique using cautery and forceps is a simple, effective treatment and diagnostic procedure for eruptive vellus hair cysts, with no recurrence after 4 months.

This case report describes a 22-year-old woman with a nevoid plaque termed localized follicular hamartoma, characterized by skin-colored papules and specific cellular and structural features.

In this case report, a four-year-old girl was diagnosed with vitamin D-dependent rickets type II, manifesting as diffuse alopecia, frontal bossing, hypoplastic teeth, and skin-colored papules, due to a genetic mutation causing resistance to 1.25-dihydroxy vitamin D.

This review discusses the history and composition of permanent hair waving products for different hair types and reports no new research findings.

Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.

This case study highlights congenital atrichia with papular lesions as a cause of total body hair loss, characterized by the absence of hair follicles and the presence of skin-colored papules.

This report describes two cases of nevus lipomatosus superficialis with the unusual feature of dilated hair follicles, emphasizing the need for precise histopathological diagnosis to differentiate from similar conditions.

This study found that a young male Maine Coon cat with a tortoiseshell coat, which typically indicates unusual sex chromosomes, was fertile, carrying both XX and XY cell lines. The researchers recommend genetic testing for tri-colored male cats before breeding decisions.

In this case report, a benign trichoadenoma was identified in a 42-year-old man as a skin-colored nodule on the cheek, with histopathology confirming the diagnosis and differentiating it from similar conditions like pilomatricoma and sebaceous cyst.

This study found that recombinant type III collagen may aid skin aging management by promoting fibroblast proliferation and migration, with a modest impact on inflammatory marker IL-6, though it did not significantly affect TNF-a secretion in vitro.

This study found that follicular unit transplantation using specific techniques may improve the natural appearance of transplanted hair in patients with male-pattern hair loss.

This study found that coloring white facial hair is an effective and feasible adjunct to intense pulsed light therapy for hair removal, with similar efficacy between using black eyeliner and black hair dye.

Pilocarpin can cause hair regrowth and color change in some cases but not in others, and it may have side effects in animals.

This study found that the maximum infrared temperature of laser-irradiated hair depends on melanin type, with eumelanin-rich hair reaching higher temperatures than pheomelanin-containing hair.

This chapter reviews the formation of natural hair color, strategies for artificial coloring, and future trends, without presenting new research findings.

This review discusses the use of trichoscopy for diagnosing systemic diseases and concludes that certain trichoscopic features may help dermatologists suspect these conditions.

This article examines microscopic structural differences and pigment distribution in various rabbit hair colors and reports no clinical results.
