Are There Any Side Effects to be Aware of?

Like any medication, both minoxidil and finasteride can have side effects. Minoxidil's most common side effects include scalp irritation, dryness, or itching. Some people might experience unwanted hair growth on areas where the minoxidil accidentally spreads. Finasteride's side effects can include a decrease in sexual desire, erectile dysfunction, or decreased semen volume, though these effects are relatively rare. It's important to talk to your doctor if you experience any side effects or if you're concerned about them.
