This review examines scalp contact dermatitis, attributing most positive patch test reactions to hair dyes, hair cleansing products, and medicaments, but presents no new research findings.

This study reported a case of a 34-year-old male developing allergic contact dermatitis to minoxidil solution, with positive patch test reactions attributed to the solution's ingredients, highlighting the potential for propylene glycol sensitivity.

Up to 50% of scalp hair can be lost before it appears thin, and treatment is only needed for hair loss caused by diseases or deficiencies.

This article reviews how to take a thorough dermatological history, conduct examinations, and discusses diagnostic tools; it reports no new clinical findings.

The document concludes that hair loss in women is complex, often linked to aging, health conditions, and nutritional deficiencies, and emotional impacts should not be underestimated.

This study found that, among 100 patients with alopecia areata, the most prevalent subtype was patchy alopecia areata, with characteristic trichoscopic features including black dots, yellow dots, and empty hair follicles.

In a non-blinded study with 12 Japanese participants, applying a lotion containing Lactiplantibacillus plantarum N793 to the scalp for 24 weeks significantly increased hair density and reduced hair loss, with participants reporting improvements in hair thickness and volume, and the treatment deemed safe.
