Progranulin overexpression leads to shorter, thinner hair and increased cell death in mouse hair follicles.

In this study, a 26-year-old woman with polycystic ovarian disease and advanced hair loss (Ludwig Grade III) showed reduced hair shedding and improved hair density after four sessions of platelet-rich plasma combined with microneedling, with no reported adverse effects.

This study reported that the PTGER2 gene is strongly expressed in cashmere goat skin and its expression tends to decrease from the anagen to telogen stages of the hair follicle cycle.

The study found that women with hyperandrogenic PCOS have higher levels of AKT1 and AKT2 proteins in their cells, which may lead to cell dysfunction.

This study found that nitrate, rather than ammonium, significantly enhances phosphate starvation responses in plants through a regulatory cascade involving NIGT1, SPX, and PHR1 proteins.

This study reported that patients with decreased kidney function had significantly higher levels of ethyl glucuronide in hair compared to healthy volunteers, suggesting caution when using hair EtG levels to assess driving qualifications.

This study suggests that the hydrogel nanoparticle formulation of hair growth-promoting compounds may enhance hair follicle penetration and induce hair growth in tested models, demonstrating its potential as a hair growth treatment.

GLP-1 therapies can cause hair loss, but hair often regrows after stopping or reducing the drug.

This article reviews the terminology and factors associated with female hair loss, particularly distinguishing it from male pattern hair loss, but reports no new clinical results.

In this study, researchers found that the congenital absence of the palmaris longus muscle was relatively uncommon and showed no significant differences according to sex, side, or digit ratio (2D:4D) among individuals assessed using MRI and radiographs.

A woman developed rare, unexplained curly hair on her scalp and eyelashes.

This case report from Nepal describes a five-year-old boy with Hutchinson Gilford Progeria Syndrome experiencing ocular manifestations, highlighting the role of ocular senescence in this genetic disorder.

This case report observed that resection of a lesion using a carbon-dioxide laser in a Labrador retriever with lingual hair heterotopia led to positive outcomes, although hair partially regrew.

This study found a 31% decrease in antidepressant use following cosmetic surgery, suggesting that such procedures may influence medication use by improving self-esteem.

This case report describes a patient with glaucoma who developed reversible hyperpigmentation and hypertrichosis after using bimatoprost eye drops, aiming to explore prostaglandin analogues' potential roles in hair and depigmentation therapies.

This study found that NGAL expression increased in calcium-induced keratinocyte differentiation in vitro and was highly elevated in psoriasis-like skin conditions and skin cancers, suggesting a role in skin hyperplasia and homeostasis.

A patient with "strawberry gingivitis" improved after correct treatment for Granulomatosis with polyangiitis, highlighting the need for early diagnosis.

In this study, researchers developed EPO-derived peptides that enhanced hair growth by stimulating dermal papilla cells and increasing IGF-1 expression without triggering systemic erythropoietic effects in tested models, indicating a promising approach for treating hair loss.

This article presents a diagnostic quiz based on clinical images and reports findings from the mentioned article but does not provide new clinical results.

This study reported that both phlebotomy and oral contraceptive pills with cyproterone acetate effectively improved insulin resistance and androgenic profiles in women with PCOS, but OCs had more impact on regularizing menstrual cycles.

Immune system changes may contribute to female pattern hair loss.

This study found that premenopausal women with female pattern hair loss had a higher prevalence of metabolic syndrome compared to healthy controls.

This study suggests that measuring glycation in hair may serve as a useful indicator of long-term blood glucose control in diabetic patients.

This study found that the uric acid to creatinine ratio had excellent diagnostic ability for polycystic ovary syndrome, with significant associations to metabolic and hematologic changes in PCOS patients.

This study highlights a potential association between semaglutide, a diabetes medication, and increased reports of hair loss, with researchers calling for more rigorous clinical trials to confirm and better understand the risk.

This study reported that platelet-rich fibrin (iPRF) therapy may improve scalp health and hair appearance in women, showing beneficial changes in scalp hydration, redness, oiliness, and hair density, thickness, and loss.

Pili annulati is caused by a protein metabolism disorder affecting hair structure.

This study found that an alcoholic extract of Glycyrrhiza glabra significantly reduced prostate weight and serum testosterone in castrated rats given testosterone, indicating potential antiandrogenic properties.
