Finasteride and minoxidil are the two most studied treatments for male pattern hair loss, and they work in different ways. That is why providers sometimes prescribe them together. This guide explains how each works, why they may be combined, and the safety points that apply to both.
How each one works
Finasteride lowers DHT, the hormone that causes sensitive hair follicles to gradually shrink. Oral finasteride is FDA-approved for male pattern hair loss. See how finasteride works.
Minoxidil is thought to act on the hair growth cycle and on blood flow around the follicle. Topical minoxidil is available over the counter and is FDA-approved for hereditary hair loss. Oral minoxidil is sometimes prescribed off-label.
Why they may be combined
Because finasteride addresses the hormonal driver of pattern hair loss and minoxidil acts on the growth cycle, the two target different parts of the process. Some studies have found better outcomes with the combination than with either alone, though results vary and study designs differ. Whether a combination makes sense for you is a provider's decision.
Ways they can be prescribed together
- Oral finasteride with topical minoxidil as separate products.
- A compounded topical formula combining both, prepared by a licensed pharmacy for an individual patient.
- Other combinations based on the provider's judgment.
Compounded medications are not FDA-approved. Read how compounded hair loss treatment works.
Side effects and safety
- Minoxidil: scalp irritation, itching, unwanted facial hair where topical product spreads, and temporary shedding when starting. Oral forms can affect blood pressure and heart rate and need a provider's review.
- Finasteride: possible sexual side effects and mood changes. It lowers PSA, a prostate cancer screening test.
- Pregnancy: finasteride must not be taken or handled by anyone who is or may become pregnant. Minoxidil is also generally not recommended during pregnancy or breastfeeding.
Report side effects to your provider, and do not start, stop or change either medication on your own.
What to expect
The most consistent benefit of treatment for pattern hair loss is slowing or stopping further loss, and some people see partial regrowth. Responses vary, change is slow, and benefits depend on continuing treatment. Providers typically evaluate response over months rather than weeks. See minoxidil shedding.
