January 2017 in “Clinical and medical investigations” This research reports that herb lotions for alopecia areata, particularly those containing salvia miltiorrhiza radix, were effective in promoting hair regrowth in 64.8% of severe cases, akin to DNCB and SADBE.
February 2026 in “Indian Journal of Dermatology” This study from a dermatology department found that patch test positivity for allergic contact dermatitis is lower in geriatric patients than in adults, likely due to age-related immune changes and reduced allergen exposure.
This review reports no new results and discusses various topical treatments, noting that fluocortin butyl ester offers anti-inflammatory effects without systemic side effects, while combinations outperform single-agent therapies in managing hyperpigmentation.
January 1987 in “Side effects of drugs annual” This chapter reviews dermatological drugs and cosmetics, identifying common allergens and preservatives linked to contact dermatitis without reporting new clinical results.
June 2026 in “Frontiers in Allergy” In this study, patients with scalp seborrheic dermatitis exhibited distinct patterns of allergen sensitization tied to symptoms, impaired skin barrier, and altered microbiota, emphasizing the need to consider allergen exposure, barrier status, and microbial balance when interpreting patch test results.

,
November 2002 in “Australasian Journal of Dermatology” This case report describes a 24-year-old woman with androgenetic alopecia who developed sensitivity to topical minoxidil and later to saw palmetto after using a minoxidil and retinoic acid preparation.
14 citations
,
January 2008 in “Gynecological Endocrinology” This study reports that in women with non-tumor hyperandrogenism, a decrease in serum testosterone from insulin-sensitizing therapy like metformin may indicate a low likelihood of having an androgen-secreting tumor.
14 citations
,
July 1987 in “Contact Dermatitis” This article lacks an abstract and presents no new findings, primarily discussing topical minoxidil sensitization in androgenic alopecia.

,
February 2008 in “Atmospheric environment” In this study, researchers found that human scalp hair, particularly when unwashed, can significantly react with ozone, reducing personal ozone exposure and increasing exposure to volatile reaction products.
October 2024 in “Frontiers in Immunology” This study proposes that intranasal exposure to PTx and autoantigen in an animal model can trigger autoimmune disease, supporting the idea that subclinical nasal colonization by BP may cause alopecia areata.
This study found that patients with scalp seborrheic dermatitis exhibited distinct allergy sensitization patterns linked to skin barrier dysfunction and changes in scalp microbiota, suggesting the importance of context in interpreting patch test reactivity.
38 citations
,
June 2018 in “Archives of Toxicology” This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.
