The hormonal picture
Estrogen supports the hair growth cycle. As estrogen and progesterone decline through perimenopause, the relative influence of androgens on the scalp increases. For women with a genetic predisposition, this shift can unmask or accelerate female pattern hair loss — gradual miniaturization of follicles, most visible as a widening part and reduced density at the crown.
Not all menopausal hair change is pattern loss, though. Diffuse shedding can also follow the stress, sleep disruption, and metabolic changes of this life stage, and thyroid disorders become more common with age. Getting the diagnosis right matters, because the treatments differ.
The main treatment lanes
Topical and oral minoxidil
Topical minoxidil remains the most established option for female pattern hair loss at any age. Low-dose oral minoxidil has become an increasingly common prescription alternative for women who find topicals impractical — it requires a prescriber conversation about blood pressure and other considerations.
Anti-androgens
Spironolactone is prescribed off-label when a clinician judges that androgens are a meaningful driver. It’s a long-established medication with decades of clinical familiarity, and the hair conversation is one a prescriber can have alongside your broader menopause care.
Hormone therapy — a conversation, not a hair treatment
Menopausal hormone therapy is prescribed for menopause symptoms, not as a hair-loss treatment, and its effects on hair vary. If you’re considering HT for other symptoms, hair is worth raising as part of that conversation with your clinician rather than the reason for it.
Foundations
Iron status, vitamin D, thyroid screening, protein intake, and scalp care don’t replace treatment — but deficiencies in any of them can blunt whatever else you do.
Questions worth asking a prescriber
- Is my pattern consistent with female pattern hair loss, diffuse shedding, or both?
- Should we check ferritin, thyroid, and vitamin D before starting anything?
- Is oral minoxidil appropriate for me, or should I start topical?
- Does anything in my history make spironolactone a good or bad candidate?
