A product which is used topically without there being any scientific proof of its effectiveness. It has hardly any bibliographical references in medical literature and a single published study indicates its very low effectiveness in hair regrowth (Orasan 2016). Since the last update, we have not found published data on its excretion in breast milk. The small dose used and very low plasma absorption of most topical dermatological preparations make it unlikely that a significant amount will transfer into breast milk. It is normal to lose hair in the months following pregnancy and this has nothing to do with breastfeeding but with the end of the resting phase in hair loss that occurs during pregnancy. Within 12 months of giving birth, the hair grows back without causing alopecia.
