Are Crown, Lush Lox and ReGrow Fuel FDA approved?

No. They are compounded for an individual prescription, and FDA does not verify the safety, effectiveness or quality of compounded drugs before they are sold. [6] Spironolactone tablets are FDA approved, but not for hair loss. [5]

Is topical minoxidil an option instead of a pill?

Yes. Minoxidil 2% or 5% for women is sold without a prescription and is the FDA-approved treatment. [1] Its label says to stop if you get chest pain, a rapid heartbeat or swollen hands or feet. [3]

Can I take spironolactone if I might get pregnant?

Tell your clinician first. The label says to avoid spironolactone in pregnancy because it may affect a male fetus. [5]

Do I need blood tests before treatment?

Sometimes. A clinician may test for a thyroid problem or low iron when your history points there, and may check potassium before spironolactone. [2, 5]

What are my treatment options for thinning hair as a woman?

Medical reviewer of record:

Updated 2026-09-28

Female pattern hair loss is the most common cause of thinning hair in women, but thyroid disease, low iron and shedding after stress or childbirth can look similar. ^{1, 2} Topical minoxidil is the FDA-approved treatment. ¹ Oral minoxidil and spironolactone are prescription options a clinician may use off label. ^{1, 4}

What does a clinician check first?

A widening part or thinning on top that builds over years points to female pattern hair loss. ¹ Shedding a few months after childbirth, illness or stress often settles within 6 to 9 months, and treating a thyroid problem or a nutrient shortfall can let hair regrow. ²

What do the safety labels say?

Minoxidil tablets are approved only for hard to control high blood pressure. Their label says hair growth is not an approved use and lists fluid retention, a faster heartbeat and thicker body hair. ⁴ Spironolactone can raise potassium, and its label says to avoid it in pregnancy. ⁵

How long before I know if it works?

Dermatologists judge a treatment after about 6 to 12 months of steady use, and results vary from person to person. ¹ If you stop minoxidil, the benefit fades within weeks to months. ^{1, 3}
