This case report details a unique instance of pityriasis rubra pilaris affecting only the scalp, highlighting novel trichoscopic features and emphasizing the importance of recognizing this rare presentation for improved diagnosis and treatment.

This study found that individuals with both androgenetic alopecia and metabolic syndrome had thicker subcutaneous adipose tissue in the frontal scalp, along with unfavorable metabolic parameters, compared to those without metabolic syndrome.

This study found that a dietary supplement containing fermented soy, ornithine, arginine, and Tricovel® Tricoage45+ significantly reduced hair loss and promoted hair growth in menopausal women after 8 to 12 weeks.

This study found that patients with androgenetic alopecia, particularly those with a U pattern, are prone to insulin resistance, with high fasting blood sugar and triglyceride values.

This study developed a method for expanding human dermal papilla cells in vitro while maintaining their ability to induce hair growth, advancing the potential for follicular cell implantation as a treatment for hair loss.

This review discusses the evolution and studies of injection lipolysis for fat reduction, highlighting the need for more research to ensure patient safety and treatment efficacy; it reports no new clinical results.

This study found that the distribution of mast cell prostaglandin d-synthase in the scalp spatially aligns with the pattern of androgenetic alopecia, suggesting a programmed vulnerability to hair loss.

This study identified polymorphisms in HGT-KRTAP7-1 and KRTAP8-1 genes in Argentine llamas that may impact fiber characteristics by altering amino acid residues critical for keratin-associated protein properties.

This study observed that in the bald scalps of male patients with androgenetic alopecia, there was a significant downregulation of the PPAR signaling pathway, suggesting reduced adipogenesis potentially influencing hair cycling processes.

This study identified several patient-specific factors that can predict both the likelihood of undergoing and failing a post-TURP void trial, aiding in the selection of candidates for immediate assessment.

This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Scientists successfully created fully functional hair follicles using bioengineering methods and stem cells.

This study introduced a validated LC-MS/MS-based method for profiling long-term steroid concentrations in human scalp hair, offering potential applications in endocrinology research.

This study found that 6-year-old children experienced a significant increase in hair cortisol levels when entering third grade, which was linked to their level of inhibitory control.

In this study, a modified Xception deep learning model achieved a 92% accuracy rate in diagnosing hair and scalp disorders, significantly outperforming other models, suggesting AI could improve dermatological diagnostics' accuracy and accessibility.

This study found that IBS is positively associated with psoriasis, rosacea, and urticaria, but inversely associated with acne and vitiligo.

The researchers reported that a child with epilepsy developed encephalopathy after an asymptomatic COVID-19 infection, confirmed by clinical and laboratory assessments showing post-COVID19 effects.

In this study, eight healthy dogs showed hair and skin damage, including hair shaft fractures and skin irritation, after repeated application of Clairol Hair Dye Flaxen Blonde.

This article evaluates clinical and scientific literature on post-finasteride syndrome, concluding that finasteride and dutasteride may cause persistent sexual, neurological, and physical adverse side effects in a subset of men.

Applying valproic acid on the scalp increased hair growth in men with hair loss.

This study found that a hydro-alcoholic extract of Roselle petals may reduce free radical production during UV-induced photodecomposition of antibiotics, potentially offering protective benefits for patients using similar topical antibiotics.

This case study of a 9-year-old girl with alopecia areata reported that her homoeopathic treatment using Lycopodium clavatum led to reduced hair loss, halted formation of new patches, regrowth progression, scalp stabilization, and emotional improvement over a long-term follow-up.

This case report highlights the role of mental symptoms in tailoring homoeopathic treatment for a 24-year-old male with alopecia barbae, a localized non-scarring hair loss condition affecting the beard, emphasizing the psychological component in its management.

Using both minoxidil and finasteride together on the scalp works better for male hair loss than using either one alone.

This study found that marine-derived collagen peptides slightly promoted hair matrix proliferation and prolonged hair growth phase in human hair follicles ex vivo, suggesting potential benefits for hair loss treatment.

This study found that topical rosemary solution was as effective as Minoxidil 2% in treating alopecia areata on the scalp.

This study found that cortisol increases mac25/IGFBP-rP1 expression in osteoblast-enriched cells from fetal rat calvariae, indicating transcriptional regulation which may influence IGF and insulin effects in bone.

This study found that sodium butyrate, a metabolite from the HF microbiome, significantly delayed catagen onset and promoted key physiological processes in cultured human hair follicles.

Taking 1mg of finasteride daily for hair loss can lower PSA levels by 40-50%, so to keep PSA effective as a cancer screening tool, the PSA value should be doubled during treatment.
