Finasteride 1mg and Biotin 10,000, is this a good combination to treat hair loss? (Photo)

It really depends on the cause of one's hair loss. Biotin has little role for most, so it's unlikely that will be beneficial. If you are on chronic antibiotics or various medications or have bowel disease biotin may be worth while.  As far as finasteride goes, it's only beneficial for male pattern balding. See a specialist in hair medicine to guide you on diagnosis and treatment.
