Clean and dry the scalp area before applying the
medication. You may apply this product to damp hair. To use the solution,
fill the applicator with 1 milliliter of medication (to the 1 milliliter
line), or use 20 drops. Part your hair in the area of thinning and apply
the solution evenly to the affected area of the scalp. Gently rub in. Allow
the solution to dry completely before using other styling products (such as
gels, mousse) or before going to bed.
To use the foam, rinse your hands in cold water and dry
well. Apply about 1/2 capful of foam to the scalp and rub in gently. Allow
the foam to dry completely before styling or going to bed.
If scalp irritation is a problem, you may need to avoid
using minoxidil on the same days that you have your hair colored or
chemically treated (for example, permed).
Do not use on other parts of the body unless directed by
your doctor. Do not use on skin that is red, painful, irritated, scraped,
cut, or infected. Wash hands thoroughly after application. Avoid getting
the medication in your eyes. If this occurs, rinse your eyes with large
amounts of cool water.
