A combination of finasteride 0.25% topical solution + minoxidil 5% is increasingly used to treat androgenetic alopecia (pattern hair loss).

 

It can be effective, but there are important differences between use in men and women.

​

For men

This combination is a well-supported treatment for male pattern hair loss.

​

Benefits:

• Minoxidil 5% stimulates hair follicles, prolongs the hair growth phase, and increases hair density.

• Topical finasteride 0.25% reduces scalp levels of DHT (the hormone that contributes to hair follicle miniaturization) while generally resulting in lower systemic exposure than oral finasteride.

• Studies suggest the combination is often more effective than minoxidil alone, particularly for slowing progression and increasing hair density.

​

How to use:

• Apply daily before bed

• Visible improvement typically begins after 3–6 months, with maximum benefit around 12 months.

• Continued use is needed to maintain results.

​

Possible side effects:

• Scalp irritation, dryness, itching, or flaking.

• Unwanted facial hair growth if the solution drips onto the face.

• Although less common than with oral finasteride, some men may still experience decreased libido, erectile dysfunction, or breast tenderness due to some systemic absorption.

​

​

For women

The recommendation depends on menopausal status.

​

Premenopausal women

• Minoxidil 5% is an effective treatment for female pattern hair loss.

• Topical finasteride is generally not recommended for women who are pregnant, trying to conceive, or who could become pregnant because finasteride can cause fetal harm to a male fetus.

​

Postmenopausal women

• Topical finasteride may help female pattern hair loss, particularly if minoxidil alone has not been sufficient.

• Evidence suggests it can improve hair density, although the data are less extensive than for men.

​

It is not appropriate for:

• Women who are pregnant, breastfeeding, or may become pregnant.
