How effective is spironolactone treatment for female pattern hair loss?

Spironolactone reduces some androgen effects on susceptible follicles. It may be considered when thinning follows a pattern over the part or crown and hormone sensitivity is part of the assessment. It is more likely to stabilise shedding or improve density than restore every lost hair.

Hair changes are slow because follicles move through growth cycles. Thyroid disease, iron deficiency, medicines or sudden shedding can look similar and need different care. Progress is assessed over months using examination or photographs.

Confirm the diagnosis before starting and share pregnancy plans, menstrual history, kidney or adrenal conditions and every medicine. Your clinician may check blood pressure and order blood tests. Take the medicine as directed, do not change the dose yourself and use gentle hair care.

Arrange prompt review for sudden or patchy loss, scalp inflammation, scarring, or shedding with marked fatigue. Contact the prescriber for faintness, severe menstrual changes, breast tenderness or allergic symptoms. Tell them immediately if pregnancy occurs or is possible.

Ask what type of hair loss you have, when progress should be reviewed, whether another treatment should be combined with spironolactone and what monitoring is required.
