Minoxidil is the only FDA-approved treatment for female pattern hair loss. For women, 2% solution twice daily and 5% foam once daily are both approved and work comparably; careful application limits unwanted facial hair.
Topical minoxidil is the first-line, evidence-based treatment for female pattern hair loss. It is thought to prolong the growth phase of follicles and improve blood flow to the scalp, helping hairs grow thicker and longer. It does not cure the underlying tendency, so benefits are maintained only with continued use.
2% versus 5%, and how often
For women, two regimens are FDA-approved: the 2% solution applied twice daily and the 5% foam applied once daily. Studies show the once-daily 5% foam works about as well as the twice-daily 2% solution, so the choice often comes down to convenience and tolerability. The foam contains no propylene glycol, which tends to mean less scalp irritation and itching than older solutions, and a once-daily routine is easier to keep up. Whichever you choose, apply it to a dry scalp at the thinning areas, use the labeled amount, and wash your hands afterwards. Consistency matters more than the exact product.
What to expect
Results are gradual. A temporary increase in shedding can occur in the first few weeks as follicles reset; this usually settles and is not a reason to stop. Allow at least 6 months, ideally up to a year, of consistent use before judging benefit. Common, usually mild effects include scalp dryness, itching, or flaking.
Facial-hair caution and other tips
Unwanted facial hair (hypertrichosis) is reported more often in women than men and is more likely at higher concentrations. To reduce the risk: apply only to the scalp, avoid letting the product run onto the forehead or temples, wash your hands thoroughly after each use, and let the scalp dry before lying down so it does not transfer to the face or pillow. If you notice new facial hair, tell your clinician; it usually fades after stopping but is a reason to review your regimen.
See a doctor before starting if you are pregnant, breastfeeding, or have heart problems, and if there is no benefit after a year, if shedding is severe, or if you have patchy loss, scalp pain, redness, or scarring, which suggest a different diagnosis.

Is 5% minoxidil safe for women, or should I use 2%?
Both are used for women: the 2% solution twice daily and the 5% foam once daily are FDA-approved and work comparably. The 5% foam is convenient and tends to cause less irritation, though higher concentrations can slightly raise the chance of unwanted facial hair. A dermatologist can help you pick the formulation and strength that best fit your scalp and routine.
Why is my hair shedding more after starting minoxidil?
A brief increase in shedding in the first few weeks is common and expected. It happens because minoxidil pushes resting follicles to reset and begin a new growth cycle, so older hairs are released first. This shedding usually settles within a couple of months; continue use and give it at least 6 to 12 months before judging results.
