Rogaine offers two solutions: 2 percent and 5 percent. WebMD reports that men who try the 5 percent solution report better results but have also displayed more of the side effects. Hair growth is not always satisfactory; even with Rogaine, some men report growing only thin and wispy hair or hair more similar to peach fuzz. Rogaine is most effective on men younger than 30 who have begun suffering from hair loss within the last five years.

Rogaine is most commonly used to treat inherited hair loss, but it can be used to treat other types. The company website recommends that Rogaine be applied twice daily and that results can take up to four months to show.

Rogaine is also safe for women to use.
