In this study, researchers evaluated the hair pull test and found that normal values should be reduced to two hairs or fewer, with no significant impact from hair washing, brushing, or lifestyle factors such as hair texture and medication use.

This abstract contains only supplementary material information and reports no new research findings.

In this study, a topical formulation with compounds from the monoterpenoid family significantly improved hair growth indicators like anagen:telogen ratio, hair fall, and visual hair density in men and women with pattern hair loss.

In this NIH study, female donor to male recipient sex mismatch was significantly associated with the development of vitiligo and/or alopecia areata in patients with chronic graft-vs-host disease.

This review discusses how neuroendocrine pathways influence keratin regulation in human skin and hair follicles and suggests these pathways as potential targets for new treatments of skin disorders, but reports no clinical results.

This study found that hair products commonly used by Black women exhibited hormonal activity, which could impact health outcomes and contribute to health disparities.

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.

This review discusses the potential benefits of flavonoid-containing botanicals, such as Panax ginseng, in reducing hair loss and promoting hair growth, but reports no new experimental results.

This review discusses the dermatology of nonhuman primates and emphasizes the need for a cohesive approach to study and report their dermatologic diseases, without assuming similarities to human or other veterinary conditions.

This study found that, despite a major depletion of SOX2-expressing stem cells in the pituitary, there was no effect on endocrine cell homeostasis or response to certain stressors in adult mice.

In this study, CD109 overexpression in transgenic mice led to reduced inflammation and improved collagen organization during wound healing without affecting wound closure.

This study found that female patients with frontal fibrosing alopecia are significantly more likely to have systemic lupus erythematosus compared to controls.

This study suggests that moderate elevated prolactin levels are unlikely to cause significant hair loss in women, but still warrant further diagnostic investigation to rule out a prolactin-producing pituitary tumor.

This study suggests that hydroxychloroquine may benefit some children with alopecia areata, as five out of nine patients showed improvement, although side effects like gastrointestinal intolerance and headache were noted.

The authors concluded that platelet-rich plasma (PRP) shows promising potential as a safe treatment for hair restoration in androgenic alopecia, though further research is needed to refine its use and confirm long-term effects.

This review discusses frontal fibrosing alopecia and reports no clinical results; the authors note that no therapeutic options tested, including corticosteroids, finasteride, and minoxidil, have shown clear benefits.

This study found that bee venom promoted hair growth in mice and inhibited a key enzyme involved in testosterone conversion, suggesting its potential as a 5α-reductase inhibitor and hair growth promoter.

This study found that mammary resident macrophages play a key role in mammary tissue development by influencing cell division and maintaining mammary stem cell activity through the TNF-α-Cdk1/Cyclin B1 signaling pathway, highlighting their importance in the mammary stem cell niche.

In this study using data from young women in West Bengal, India, the researchers identified that leptin signaling impairment, insulin resistance, and specific gene mutations significantly contribute to PCOS, with obesity commonly manifesting in affected individuals.

In this study, fetal stem cells were identified in adult human hair follicles long after childbirth, indicating potential for autologous therapies due to their pluripotent characteristics.

This article discusses the surgical technique of hair transplantation in women and offers insights on postoperative care and planning for improved patient outcomes, without presenting new clinical findings.

This review outlines diagnostic possibilities for diffuse, nonscarring hair loss in women and reports no new clinical findings.

This case study observed hair shedding in an 8 1/2-year-old girl treated with carbamazepine, which ceased after stopping the medication.

This review article highlights that mesotherapy, a popular non-surgical procedure in aesthetic dermatology, involves injecting a mixture of compounds into the skin for purposes like skin rejuvenation and hair loss treatment, but lacks large-scale studies on its efficacy and safety.

This study reports that the global age-standardized incidence and disability-adjusted life-year rates of alopecia areata decreased from 1990 to 2019, with the highest increases in incidence seen in some low SDI regions and countries like Kuwait and South Sudan.

This review examines the methods and challenges in androgen laboratory diagnostics, discussing their advantages, limitations, and evolution; it presents no new experimental results.

This study found that TRH modulates specific keratins in human scalp tissue, suggesting its potential influence on hair growth and the need for further exploration of neuroendocrine controls in keratin expression.

This study found that a newly identified mutation in the hairless gene in mice led to decreased Hr mRNA levels and changes in gene expression related to hair follicle development.

This study found that cardamonin may inhibit OSCC cell migration, proliferation, and invasion by affecting the PI3K/AKT pathway, suggesting its potential as a treatment.

This study found that maternal melatonin supplementation improved fur quality in Rex rabbit offspring by increasing hair follicle density and altering melatonin receptor gene expression in several organs.
