I have androgenic pattern hair loss, can I take Biotin with Finasteride and Minoxidil?

Biotin supplements won't hurt your progress or results. But like others have said, it will only aid your hair if you have a deficiency, which is not very common (and you doctor can check this for you if you'd like to know for sure).

If you do not have deficiency of biotine , you would have no benefit with biotine intake. I dont advice to use finasteride because of
possible side effects and being under
the necessity of using that chemical for almost life long to stop hair
loss.You may start to use minoxidil %5 to thicken the crown area and stop hair
loss.You would better planning to have an
exam at hair loss expert for hair restoration surgery when you fell
uncomfortable about hair styling or total loss of hair..

Most people are not biotin deficient which makes supplementing with biotin a waste of money. Please see your physician to determine if there is any chance you could be biotin deficient.
