minoxidil androgenetic alopecia pustular contact dermatitis corticosteroid scalp allergic contact dermatitis female pattern hair loss Rogaine

TLDR A woman had an allergic skin reaction to a hair loss treatment called minoxidil.

A 30-year-old woman developed pustular contact dermatitis after using minoxidil 5% for androgenetic alopecia. She presented with pustular, pruriginous lesions on an erythematous area of her forehead and scalp after one week of treatment. Physical examination revealed papulopustules and papulovesicles on an oedematous, erythematous area. Without a biopsy, a diagnosis of drug-induced pustular contact dermatitis was made. The minoxidil treatment was stopped, and after five days of corticosteroid treatment, the lesions completely resolved. The authors noted that while minoxidil is the only approved treatment for female pattern hair loss and is commonly used, it has been associated with scalp allergic contact dermatitis, making this case an uncommon reaction to a frequently used drug.

community Minoxidil Response Bottlenecks: Why Sulfation and Transport Matter (And Where Tretinoin Fits In)

nkrata in Research 461 upvotes 9 months ago

Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.
