Biotin and Propecia – Hair Loss Information by Dr. William Rassman

Hello Dr. Rassman,

Would there be a negative effect in taking Propecia and a dietary supplement called Biotin 2500, which has about 2500 mcg of biotin, at the same time?

Thanks for your time.

I do not see a problem combining Propecia (finasteride 1mg) with biotin.
