Hi, Thanks for posting in HCm. I understand your concern. Adgain is a nutritional hair supplement which consists of ingredients: Calcium D-pantothenate, L-Cystine, Thiamine mononitrate, Brewers yeast, Biotin, Iron and Zinc. It supplies hair with the fortifying substances which improves hair structure, strengthens hair and increases the resistance of hair to mechanical and chemical damage. Finasteride is used to treat male pattern baldness (androgenetic alopecia). It acts by decreasing the amount of DHT (Dihydrotestosterone) and leads to increased hair regrowth with slower hair loss. You can take both these medications together as advised for your hair loss problem, as there are no known interactions existing between them. Hope the information provided would be helpful. All the best.
