How does Eflornithine work for Hirsutism?

Eflornithine blocks the action of an enzyme called ornithine decarboxylase, which is found within the hair follicles. Blocking this enzyme will slow down the growth of unwanted hair on the face and under the chin in PCOS women. It may also make the hair finer and lighter. It does not remove hair or cause the hair to fall out.
