This study suggests that breast cancer-associated phospholipids may alter the X-ray diffraction pattern of hair, potentially enabling the development of a sensitive and specific screening test for breast cancer.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

A girl's severely tangled hair couldn't be fixed and had to be cut due to a rare condition called plica neuropathica.

In this study, researchers formulated a hair tonic using various herbal extracts and reported effective antifungal and antibacterial properties, along with good consistency, spreadability, homogeneity, appearance, and pH balance.

This article discusses the composition and function of the dermal papilla in hair follicles, focusing on its role in hair shaft generation and suggesting that cell loss in this area may contribute to hair loss.

This case report describes a canine with alopecia areata universalis treated with oral ciclosporin, which was associated with hair regrowth, but some areas remained hairless after 17 months.

This study demonstrated that intramuscular corticosteroids were effective for severe alopecia areata, with significant hair regrowth in 80.2% of patients, though a high relapse rate was noted post-treatment. Nail involvement and disease duration over six months negatively impacted outcomes.

Hair enzyme activity predicts minoxidil success in Brazilian women with hair loss.

This study shows that differences in Hoxc gene expression in hair follicle mesenchyme along the body axis contribute to regional variations in mammalian hair growth.

This source describes the potential of various herbal treatments, such as aloe vera and amla, as natural alternatives for managing hair loss and enhancing hair health, noting their benefits include fewer side effects, affordability, and multiple application methods.

This case report suggests that patchy hair loss in a child may be an atypical sign of persistent head lice infestation.

In this study, the researchers found that a manual micrometer caliper is a reliable tool for planning hair transplant surgery and accurately measures the short axis of the hair shaft.

This report describes a rare case of severe combined immunodeficiency caused by a FOXN1 gene variant, complicated by Epstein-Barr virus infection and high-grade B-cell lymphoma, leading to the infant's death despite treatment efforts.

This study found that 3% topical minoxidil decreased hair shedding and promoted hair growth in women with androgenetic alopecia.

This study found that phenylbutazone and fluocinolone acetonide have similar anti-redness effects in both haired and hairless animals, making hairless rats a potential alternative for testing without needing depilation.

In this study, the presence of the HPV11-E2 protein in transgenic mice was found to increase and vary the expression of a reporter gene in hair follicle bulge regions.

This study reports that the metanephrine content was significantly higher in patients with alopecia areata compared to those without the condition.

This study found that adding galeotomies to subgaleal tissue expander placement for post-burn alopecia resulted in faster scalp expansion and reduced complications of expander extrusion.

This review discusses unique anatomical features and management strategies for crown alopecia but reports no new clinical findings, focusing instead on surgical techniques for natural-looking results and optimal density.

This review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

This study examined the microscopic characteristics of hair or feather in five animal drug components of the Shenrongbian pill, identifying distinctive medulla cell shapes and hair cuticle patterns for each component.
