This case report suggests that topical imiquimod cream may be an effective alternative treatment for generalized discoid lupus erythematosus without systemic involvement.

Minoxidil can cause pustular allergic reactions on skin.

This study found that minoxidil sulfate and pinacidil did not activate K channel currents in hair follicles, suggesting their effect on hair growth might occur through other mechanisms like increased blood flow.

This article discusses common dermatologic side effects of psychopharmacologic agents such as eruptions, urticaria, and photosensitivity, but it reports no new research findings.

This case study observed that three girls with alopecia experienced complete hair regrowth after avoiding balsam of Peru and related fragrances, suggesting contact allergy played a role in their hair loss.

This review describes how male hypogonadism can lead to various skin and hair symptoms, as well as potential dermatological reactions to hormone treatments and reports no new clinical results.

In their 1957 study, Neuman and Neuman suggested that magnesium deficiency may inhibit the ion exchange process required for calcium ions to enter extracellular fluid, potentially affecting calcium mobilization.

This study reports a novel TRbeta gene mutation associated with resistance to thyroid hormone syndrome, which may contribute to various forms of alopecia in the affected family members.

This case report describes an 18-year-old male with kerion celsi from Trichophyton tonsurans infection whose condition improved with terbinafine treatment, and highlights that although IL-17A expression increased in skin lesions, it was associated with disrupted antimicrobial peptide expression and severe inflammation, causing tissue damage.

In this case report, the authors linked acute psoriasiform contact dermatitis of the forehead and scalp to a low-laser light cap, identifying DMDE in the fabric as a likely cause.

This study found that women with female pattern hair loss had significant hormonal imbalances, specifically involving adrenal androgens, suggesting these may play a central role in the condition's development.

The man has a disease causing skin patches, thickened nerves, and mild muscle weakness.

This study reported that in degenerative alopecia, Zn²⁺/Cu²⁺-dependent proteases are downregulated and destabilized, and a specially developed microneedle patch reactivated these enzymes, reduced senescence, and enhanced hair regeneration in an animal model.

This case report describes how a 23-year-old woman experienced eyebrow thinning and hair loss linked to cosmetic use, with diagnostic tests confirming follicular damage. Discontinuing the product led to eyebrow regrowth, highlighting potential risks from cosmetics and the value of non-invasive diagnostics for evaluation.
