Q. Is shampooing necessary before applying?
A. No.

Q. Can I continue my normal hair care routine, using conditioners, hair sprays, etc. while using minoxidil?
A. You should continue your haircare routine as normal, but choose haircare products carefully and make sure they don't interfere with the absorption of minoxidil. Choose conditioners suitable to your hair type and be sure to rinse them out thoroughly. If using hair sprays, styling gels or mousse, make sure that minoxidil is completely dry before applying.

Q. Can I use a hair dryer while using minoxidil?
A. A hair dryer may be used to dry hair after shampooing, but should not be used to dry the medication as the heat will cause it to evaporate before being absorbed into the scalp. minoxidil should be allowed to dry naturally.

Q. Can I go swimming or take a shower while using minoxidil?
A. Yes, but you should wait about four hours after applying minoxidil before getting your hair wet, so the solution has had time to dry and start working. And don't reapply minoxidil until your hair is completely dry.
