This study found that permanent alopecia can occur after certain chemotherapy treatments and presents as nonscarring hair loss similar to androgenetic alopecia, with specific histological features that could be misdiagnosed without proper clinicopathological correlation.

This study found that participant self-assessments suggested greater improvement in the texture and wrinkles of facial skin treated with PRP compared to normal saline, though dermatologist ratings showed no significant difference.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This review discusses the use of cosmetic nanocarriers to improve hair appearance and reports no new experimental results.

In this study, the authors reported that feeding cashmere goats with essential oil-cobalt significantly enhanced their growth, meat quality, and fiber quality, while stimulating immune-related physiological changes.

This review discusses medication-induced gray hair repigmentation, highlighting that certain anti-inflammatory drugs and melanogenesis stimulators can cause diffuse repigmentation, though evidence remains low-quality and these medications are not currently indicated for this purpose.

This report describes the unexpected development of alopecia areata in kidney-pancreas transplant recipients undergoing cyclosporine-based immunosuppressive therapy, suggesting a complex relationship between the treatment and disease.

This study found that bovine lactoferrin promotes hair growth in mice by enhancing dermal papilla cell proliferation through the Erk/Akt and Wnt signaling pathways.

This text provides contact information and no new research findings are reported.

This study examined the genetic basis for the curly hair trait in Mangalitza pigs, finding two specific genetic variants that contribute to this distinctive phenotype through autosomal dominant inheritance.

This study found no significant association between premature hair graying and serum ferritin or vitamin D levels in young adult males at Universitas Sumatera Utara.

This review discusses the biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This review discusses the impact of endocrine-disrupting chemicals on pediatric health, linking them to various disorders, and calls for improved biomonitoring strategies and precautionary policies.

This study found that targeting both hormonal and immune pathways improved treatment outcomes in androgenetic alopecia patients with an under-recognized inflammatory component called PIILIF, which may contribute to treatment resistance.

In this case report, researchers detailed a giant proliferating pilomatrixoma in a 36-year-old woman, emphasizing the importance of complete excision to prevent recurrence or potential malignant transformation, distinguishing it from malignancies like angiosarcoma or melanoma.

This study analyzed soil, water, and carrot samples in Vietnam, and found that organic farming can reduce heavy metal levels in carrots compared to conventional methods, potentially improving their nutritional safety.

More research is needed on CCCA in children, especially Black and Asian adolescents.

In this research on cinnamon and virgin coconut oil hair tonics, F2 and F3 demonstrated stable physical properties and mild irritation potential, while formula 1 remained non-irritating but less stable regarding pH and viscosity.

This review discusses the potential risks of formaldehyde in hair keratin treatments like Brazilian blow-dry, and reports no new clinical results; it emphasizes the need for greater safety assessments including occupational exposure.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

The document concludes that proper diagnosis and treatment of nonscarring alopecias can improve quality of life and hair regrowth is possible as the hair follicle remains intact.

Photographic imaging is crucial for documenting and managing hair loss, requiring careful preparation and standardization to be effective.

This study found that normal murine hair follicles are direct targets for melatonin bioregulation, expressing receptors that are regulated in a hair cycle-dependent manner, influencing keratinocyte apoptosis.

In 2002, various drugs caused serious side effects, including vitamin B12 deficiency, heart issues, blindness, hypersexuality, allergic reactions, blood clotting problems, pupil dilation, capillary leak syndrome, muscle breakdown, hepatitis, skin reactions, and lupus.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

This study found that TRPA1-deficient mice exhibited normal cold sensitivity but had decreased mechanical response in nociceptors, suggesting TRPA1's role in mechanotransduction.
