Is It ok to take biotin and viviscal together? Or one or the other? And which version should a male take? They have men and pro.

I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Viviscal and Biotin are ok to take together. The option on which of these supplements to take is a personal choice.
