You cannot donate blood if you are taking finasteride or dutasteride due to potential risks to pregnant women. Finasteride has a shorter wait time to donate blood compared to dutasteride, and both oral and topical forms can disqualify you from donating.
After six months on Dutasteride, the user's hair is worse than before, despite previously trying finasteride and RU/Fluridil without success.
