This case report describes the first instance of juvenile hemochromatosis type 2A associated with secondary hypothyroidism, linked to a novel mutation in the HJV gene.

Human hair follicles have their own thyroid hormone system.

In this study, topical application of Hominis Placenta significantly promoted hair regrowth and increased hair density in C57BL/6 mice, suggesting its potential as a treatment for alopecia.

This study explored the effects of a common Hutchinson-Gilford progeria syndrome mutation in an inducible mouse model, revealing skin abnormalities similar to those in affected patients.

This abstract reports no new clinical results and discusses the importance of follicular unit storage for the success of hair transplantation surgery.

This study found that ZDHHC13 deficiency in mice is associated with abnormal liver function, lipid metabolism issues, and impaired mitochondrial function, highlighting ZDHHC13's regulatory role in liver metabolism.

In this cross-sectional study, researchers observed that patients with hidradenitis suppurativa, particularly women, had lower 2D:4D finger length ratios compared to healthy controls, suggesting a potential link to prenatal androgen exposure and disease severity, though further prospective research is needed to confirm this hormonal impact.

This study found that inhibiting Wnt/β-catenin signaling disrupted hemidesmosome organization in keratinocytes, suggesting potential therapeutic targets for HD-defective diseases like epidermolysis bullosa.

This study identified two novel point mutations in the hHb6 gene associated with monilethrix, suggesting these mutations could serve as diagnostic markers for this genetic hair disorder.

In this study, researchers suggest that digital microscopy using visible light could offer a more objective approach to diagnosing hirsutism by quantifying terminal hair, with future research needed to assess its usefulness in women with the condition.

This study found that patients with hidradenitis suppurativa had significantly higher levels of cell-free DNA in their serum compared to healthy controls, suggesting its potential as a biomarker for the disease.

This study found that storing hair follicle micrografts in HEPES-buffered DMEM with ACD inhibitors like aminoguanidine significantly increased hair shaft elongation compared to phosphate-buffered salt solution, suggesting improved viability for transplantation.

This article reports on three new cases of Birt–Hogg–Dubé Syndrome and emphasizes the role of genetic analysis in its diagnosis due to clinical challenges.

This study found that concentrations of haloperidol and its metabolite in human scalp hair significantly correlated with the daily dose and plasma trough levels in patients taking haloperidol.

In this study, researchers observed that hidradenitis suppurativa lesions were associated with reduced collagen and elastin, and increased neovascularization in areas with chronic inflammation.

This study found that hair follicle stem cells from the bulge region in mice and humans can be isolated and cultured to maintain their phenotype and high proliferative capacity, suggesting their potential as an accessible source for tissue engineering and regenerative therapies.

This article reviews the use of high-frequency ultrasonography to visualize nail units and scalps in dermatology, highlighting its potential benefits for disease assessment and treatment monitoring, but reports no new clinical results.

This study found that a dopamine-methacrylated hyaluronic acid hydrogel enhances the efficacy of adipose-derived stem cells in promoting skin regeneration, potentially involving the Notch signaling pathway.

This study found that heart-inspired hollow hydrogel-based scaffolds enhanced regenerative capability in osteoporotic bone defects and increased cell number when using a mechanical-assisted post-bioprinting strategy.

This study found that Hordenine promotes hair regrowth and enhances dermal-papilla cell activity in mice by activating the Wnt/β-catenin signaling pathway, suggesting potential for treating alopecia.

This report presents a rare case of suspected 3β HSD deficiency in an adult female with symptoms like male pattern hair loss and low testosterone, suggesting a non-classical presentation.

This source describes the American Board of Hair Restoration Surgery's mission to set standards and evaluate skills in hair restoration surgery, but does not report any specific study results.

This study found that a novel R343H mutation in the vitamin D receptor gene impairs its transcription activity, contributing to hereditary vitamin D-resistant rickets and alopecia in the affected family.

This study identified a novel insertion mutation in the hairless gene that may contribute to the development of congenital atrichia with papular lesions in a Pakistani family.

A new genetic mutation in mice causes permanent hair loss and skin wrinkling.

This study found pathogenic mutations in genes EDA, EDA1R, and EDARADD in 101 out of 124 hypohidrotic ectodermal dysplasia patients, revealing 23 novel mutations and indicating genetic variability.

This study found that KSR1 is essential for v-Ha-ras-mediated skin tumor formation in mice but not for MT-driven mammary tumor genesis, suggesting its potential as a therapeutic target in Ras/MAPK signaling.

This review discusses Hutchinson-Gilford Progeria Syndrome, its symptomatology, and the progress in developing treatment strategies, emphasizing that while a cure remains elusive, advances in understanding the disease's molecular mechanisms show promise for future approaches.

In this study, researchers found that overexpression of the hairless protein in Hr mutant mice disrupts inner root sheath formation by downregulating Dlx3 and associated keratins in hair follicle development.
