After neutering your users for 20 years, she finally enters request for topical finasteride:

Probably will be released a lotion lipossomada or nanossomada that avoids systemic absorption.
I wonder would topical finasteride be as dangerous as oral finasteride.
Nope, with Lipossomes or Nanossomes is impossible systemic absorption. It’s the same thing you say if I start using ketoconazole ointment daily on skin, the person may become impotent. I used Nizoral as a child for years, and never had problems, ketoconazole has much more potential for chemical castration that finasteride.
