Which outcome may occur with topical minoxidil beyond the treated scalp area?

• A. Unwanted hair growth beyond treated areas
• B. Hypertension
• C. Bruising
• D. Visual changes

Answer: (A)

Topical minoxidil can be absorbed through the skin and reach other areas, so it may stimulate hair follicles beyond the treated scalp. It works by prolonging the growth (anagen) phase of hair follicles and increasing follicle activity; when the drug reaches nearby skin, those follicles can also respond, producing unwanted hair growth in areas like the face or neck. So the best-match outcome is hypertrichosis outside the treated region. Hypertension is a systemic possibility if large amounts were absorbed, but it’s not the typical or most likely local beyond-scalp effect with standard topical use. Bruising or visual changes aren’t characteristic effects of topical minoxidil.
