Doctor Prescribed Spironolactone and Rogaine for My 19 Year Old Daughter

I have a 19 year old daughter with thinning hair. She has been tested for thyroid issues which came back negative.

Her dermotologist has prescribed spironolactone 25 mg/2x day and rogaine treatments. I’m concerned about possible side effects especially at her age. Please advise. Thank you.

I personally do not go that route for reasons like you suggested. The evidence is not strong that it will have an impact unless there are clear hormonal elements that she is being treated for. Ask your/her doctor for more information. For previous posts about spironolactones, see here.
