Summary
Minoxidil is used to treat androgenetic alopecia, which is a common form of hair loss in both men and women. It helps promote hair growth and slow hair loss by stimulating hair follicles and increasing blood flow to the scalp.
Minoxidil works by stimulating hair follicles and increasing blood flow to the scalp. It prolongs the growth phase of hair, which is called the anagen phase, and enlarges hair follicles, leading to thicker hair strands.
The usual dose of Minoxidil for adults is to apply 1 milliliter (mL) of the solution or half a capful of the foam to the affected scalp area twice daily. It's important to follow the instructions on the package or your doctor's advice.
Common side effects of Minoxidil include scalp irritation, itching, or redness. These effects are usually mild and temporary. If you notice new symptoms after starting Minoxidil, they might be temporary or unrelated to the medication.
Minoxidil is for external use only and should not be applied to other body parts. Avoid contact with eyes, nose, or mouth. Pregnant or breastfeeding women should consult a doctor before use. Always follow the instructions and consult your doctor if you have concerns.
