In this study, genetic variants in the KRT25 and SP6 genes were found to be responsible for curly hair in horses, with the KRT25 variant also causing hypotrichosis due to an epistatic effect.

In this case report, a 30-year-old male with alopecia universalis and autoimmune conditions experienced treatment failure with JAK inhibitors, including ritlecitinib, and developed severe musculoskeletal pain, indicating a potential novel adverse effect that warrants further pharmacovigilance.

This literature review on JAK inhibitors reports that ocular side effects are rare but could be significant, with an inability to establish a causal link. Clinicians are advised to monitor such adverse events and report them to drug safety agencies.

This case report describes a 37-year-old woman whose recurrent hair shedding was associated with low iron stores and a miscarriage, with improvements seen after increased iron intake.

This case report suggests that intralesional cidofovir successfully treated SCC without systemic toxicity, making it a potential alternative to consider alongside surgical excision.

This report describes a case where a woman with frontal fibrosing alopecia initially presented with symptoms resembling rosacea, but further investigation led to a diagnosis of FFA, resulting in a treatment change to oral finasteride and hydroxychloroquine.

This research identified two genetic variants that influence the white-spotted coat patterns in Holstein-Friesian cattle, involving regulatory changes in the MITF and KIT genes, confirmed through mouse models, along with possible effects on coat patterns in other cattle breeds.

African American adults and non-White children experience more hair loss episodes than White patients with alopecia areata.

This case report describes a woman whose psychiatric symptoms preceded the clear signs of systemic lupus erythematosus, which could suggest they were early indicators of SLE or related to an underlying mental disorder exacerbated by SLE.

This study observed that drug-naïve first-episode psychosis patients had higher hair cortisol concentrations than healthy controls, and these concentrations correlated with the severity of psychopathology.

In this study, baricitinib was effective in improving hair regrowth in patients with severe alopecia areata over one year, especially when treatment began within four years of symptom onset.

In this study, socially defeated mice showed increased alcohol consumption, and CRF-R1 antagonism selectively reduced drinking in these mice, suggesting a potential treatment target for stress-related alcohol use disorders.

This source does not report any results or findings, as no abstract is provided.

Baricitinib helps regrow hair in severe alopecia areata, with results varying by initial hair loss severity and episode duration.

Men with hair loss are more likely to have cholesterol issues and sleep apnea.

This study found that, although finasteride reduced dihydrotestosterone levels in males with heavy episodic drinking, it did not significantly alter brain activation or craving but was linked to a stronger desire not to drink.

This study found that individuals with a recent history of suicide attempts exhibited altered DHEA hair levels, suggesting possible dysregulation of the HPA axis as a biopsychosocial feature, and recommends further investigation into hair hormones as potential markers of suicidal crisis and vulnerability.

This review discusses the range of long-term complications, including mucocutaneous, ocular, and psychological sequelae, for survivors of Stevens–Johnson syndrome and toxic epidermal necrolysis, but reports no new clinical results.

This study found that iron metabolism, particularly serum iron and ferritin, was significantly linked to the severity of obstructive sleep apnea in individuals with androgenetic alopecia, with stronger associations observed in women.

This report discusses a 22-year-old patient with MELAS syndrome carrying the m.10158T>C mutation, and highlights the need for extensive genetic testing when initial hot-spot mutation tests are negative.

This study found that in men with androgenetic alopecia, elevated triglycerides were the only factor consistently associated with the condition, suggesting a potential link between AGA and lipid metabolism, although other hormonal, metabolic, and sleep factors were not significantly different after propensity score matching.

This study investigated individuals with androgenetic alopecia and found that serum iron and ferritin levels are associated with obstructive sleep apnea severity, suggesting the importance of considering iron profiles in managing the condition.

In this study, iPSC-derived epidermal organoids demonstrated potential as a novel tool for regenerative medicine by producing high-performance extracellular vesicles that promote proliferation, migration, and angiogenesis in cell-free therapies for wound healing.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

Finasteride effectively lowers specific hormone levels, helping monitor treatment progress.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This article reviews finasteride's potential side effects, notably post-finasteride syndrome, and suggests that hand preference and sexual orientation might predict these adverse effects, but it reports no clinical results.
