My mother is advised by her doctor to use Propecia in order to avoid more hair loss in her head. She has a severe problem, since starting using Femara the past 6 months, because 9 years before she had breast cancer. The first 7 years she used Nolvadex and now she is taking Femara, a pill that among other factors affects her hair loss. We read that Propecia is only for men and may have some severe side effects. Is it worth for her to use it?
