The foam or solution of minoxidil applied takes some time to dry. The hairs are partially dried within thirty minutes after the solution is applied.

Minoxidil has various hair benefits, but there are also specific side effects of the medicines reported by the patients taking the drug. Some of the most common symptoms reported after drug usage include erectile dysfunction, reduced semen volume, prostatitis, reduced penile sensitivity, brain fog, heart palpitations, frequent urination, and a few others. However, it is unclear whether these side effects are a direct result of the medicine or are caused due to reasons other than the drug.

After applying the solution to the hair, the individual must sit in one place and cover the upper body with a cloth to prevent the body from getting affected. After the solution is partially dried, the person can do regular works such as walking and cooking. However, the person must not sleep until the solution is wholly dried because, in that case, the solution might be soaked by the bedsheets, which will not only make them dirty but will also cease the solution to work effectively on the hairs.

However, the drug should only be used if a medical practitioner prescribes it. Some people randomly go to medical stores and purchase the medicine. Such an intake of the drug can be very harmful to the body and can have severe complications. After consulting a medical expert, a schedule should be finalized for the intake of the drug. Adults are advised to apply 1 milliliter of the solution twice a day for getting accurate results.


Finally, it can be concluded that minoxidil is a type of medication mainly prescribed for treating hair loss. Other different names also trade the compound in the medical sector, and the melting point is very high. The medicine is available in tablet form, but it is mainly used in liquid solutions and applied to the hairs.

On average, a person can sleep after two hours of applying the solution. The solution takes some time to get dried completely, and it is crucial not to use beds in those two hours as it will lead to stain marks on the bedsheets, and the solution might not be completely effective.
