This study suggests that hair cortisol concentration may not reliably indicate psychological distress or differentiate clinical from non-clinical populations, as observed in a female PhD student over nine years.

A woman with a skin disorder was found to have hepatitis C, which may be linked, and was safely treated with methotrexate.

This study identified a homozygous frameshift mutation in the HOXC13 gene associated with pure hair and nail ectodermal dysplasia in a consanguineous Syrian family, suggesting crucial roles for HOXC13 in hair and nail development.

This study suggests that central centrifugal cicatricial alopecia may involve a CD4-predominant T-cell process with potential PD1/PDL1 pathway involvement, indicated by increased caspase 3 expression and loss of PDL1.

The correction fixes an image mistake in the original publication, but the findings on the hair treatment's effectiveness are unchanged.

This study provides evidence that ILC1-like cells can induce alopecia areata in previously healthy human hair follicles, challenging the view that it is solely an autoantigen-dependent autoimmune disease.

This study found that hair cortisol concentrations in mother-daughter pairs are a potential biomarker for cortisol responses to chronic stress, with daughter-mother similarities affected by parenting styles and children's symptoms.

This study found that the bioconjugate nanoparticle HA-P5 significantly alleviated acne and reduced sebum production by inhibiting key signaling pathways without inducing unwanted protein expression that hinders acne treatment.

The document's conclusion cannot be determined from the provided text.

This study found that hair-follicle-associated-pluripotent (HAP) stem cells can be cryopreserved for future use in nerve and spinal cord repair, with human trials being planned.

This study identified a new variety of central centrifugal cicatricial alopecia that includes patchy hair loss on the lateral and posterior scalp in African-American women, which could be misdiagnosed as traction alopecia without dermatoscopy and pathology.

This article discusses features, genetics, and diagnostic challenges of central centrifugal cicatricial alopecia in African American women but reports no new clinical results.

This study observed that a CARASIL mouse model demonstrated abnormal behavior, vascular and cellular changes, and upregulation of the TGF-β/Smad signaling pathway, indicating its potential involvement in CARASIL pathogenesis.

hHb1, hHb3, and hHb6 mRNAs start expressing at the same time in hair follicles.

The researchers reported that treatment with adipose-derived stem cell conditioned medium significantly increased hair count in the study participants, suggesting it is an effective therapy for hair regeneration.

In this study, keratin genes mHa1 and mHb4 were unable to form an extensive keratin network in one cell line, altering endogenous keratin distribution, but showed better integration in another cell line.

This study identified a new cis-regulatory element in the mouse Hr gene that influences its expression in skin and brain cells, highlighting a complex molecular network involved in hair follicle formation.

In this study, researchers created a comprehensive transcriptome map of human hair follicle compartments, identifying compartment-specific genes and providing a resource for potential therapeutic interventions.

This review provides an overview of the hairless gene in mice and humans, discussing its structure, expression, and implications for understanding skin physiology and human disorders related to gene disruption, but it reports no new empirical findings.

This systematic review and meta-analysis found that hidradenitis suppurativa is associated with an increased risk of major adverse cardiac events, including cerebrovascular accidents and myocardial infarction, although study heterogeneity affects the magnitude of risk.

The document doesn't provide enough information to summarize.

This study developed and validated an HPLC-UV method for accurately quantifying clobetasol propionate in skin and hair follicles, demonstrating its application in in vitro permeation experiments.

This atlas graphically presents hair restoration surgery techniques through drawings and photographs, without reporting new clinical results.

This article discusses the introduction of human recombinant hyaluronidase in hair restoration surgery and presents no new clinical results.

This abstract discusses the dermatological symptoms associated with hepatitis C virus infections but reports no new research findings.

This study found that 9% of tested patients had positive patch test reactions linked to hair care products, with most reactions clinically relevant and commonly involving allergens like p-phenylenediamine.

This report describes a child and his father with hereditary hypotrichosis simplex, an uncommon isolated form of hair loss, with no other ectodermal or systemic abnormalities noted.

Among pediatric alopecia areata patients treated with DPCP, this study reported complete hair regrowth in 8.8% and any regrowth in 61.8% after one year, with better outcomes for those with milder initial symptoms and longer treatment durations.
