Minoxidil (Rogaine) is a topical over-the-counter (OTC) product that can regrow and thicken hair in people with hereditary hair loss, but it might not work for everyone. It's applied to the scalp, typically twice daily. You might need to use it regularly for 2 to 4 months before you can notice results. Minoxidil (Rogaine) comes in two different strengths (minoxidil 2% and 5%), as well as different formulations, such as foam, topical solution, and spray.
Male-pattern or female-pattern hair loss
Minoxidil (Rogaine) works to improve hair growth by opening blood vessels near hair follicles. It's also thought to stimulate the hair follicles, which leads to more hair growth.

Follow the instructions on the box of your minoxidil product for specific instructions. In general, apply the medication direction to your scalp and not to your hair. Spread just enough foam or solution over your hair loss area, and gently massage the foam or solution into your scalp until all the medication is gone.
Make sure to wash your hands before and after use. If you accidentally get minoxidil (Rogaine) in your eyes, rinse them with large amounts of cool tap water.
The amount of hair regrowth is different for each person. Minoxidil (Rogaine) might not work for everyone. Check the side of the carton to see if your hair loss matches the hair loss pictures provided.
During the first 2 weeks of use, you might notice more hair shedding. This is a sign that minoxidil (Rogaine) is working and new hair is growing and replacing the old hair.
Most people notice hair regrowth after a 2 to 4 months of consistent use of minoxidil (Rogaine). If you don't notice results within 4 months, contact your provider.
Don't use minoxidil (Rogaine) more than 2 times daily (or as directed on the product instructions). Using it more often won't lead to more hair growth.
Avoid using minoxidil (Rogaine) if you're pregnant or breastfeeding because this could be harmful to your unborn baby.
Minoxidil (Rogaine) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Heart problems
Though rare, minoxidil (Rogaine) might affect your heart. People who apply minoxidil (Rogaine) topically for hair thinning is less likely to experience this side effect compared to people who take minoxidil by mouth for high blood pressure. To be safe, talk to your doctor or pharmacist before using if you have heart problems. Stop using minoxidil (Rogaine) and speak to your doctor if you notice chest pain, dizziness, or a fast heartbeat.
It's important that you read the label information carefully before use. You shouldn't use minoxidil (Rogaine) if you have a different amount of hair loss than what is shown on the product box or if your hair loss is on the front of the scalp. You should also not use minoxidil (Rogaine) if you have no family history of hair loss, if your hair loss is sudden and/or patchy, or if you don't know the reason for your hair loss.
Minoxidil (Rogaine) can be harmful to you and your unborn baby if used during pregnancy or breastfeeding. Speak to your doctor or pharmacist before using it if you're pregnant, have plans on becoming pregnant, or breastfeeding.
Some forms of minoxidil (Rogaine) are flammable, meaning it can catch fire easily. It's best you avoid smoking or being near fire or open flames right after using minoxidil (Rogaine).
Minoxidil (Rogaine) isn't approved for use in children, and it can be dangerous if it's swallowed accidentally. If your child swallows this medication, get medical help or contact your poison control center at 1-800-222-1222 right away.
