If your hair loss is due to multiple food allergy is it ok to eat propecia (finasteride) 1mg ?

Probably: You probably have hereditary baldness and this is what Propecia (finasteride) is for. Talk to your dermatologist about this.

Yes: It is ok to take Propecia (finasteride) by mouth but it probably wont treat your type of hair loss. Propecia (finasteride) is used for genetic hair loss, the type of hair loss you get passed down from one of your parents.

Yes: I;m not sure why foods are causing you to lose your hair, but there should not be any problem taking Propecia (finasteride) to stimulate hair growth.

No: Treating food allergies makes more sense than using oral propecia, which may add to problems (unless you're using Propecia for prostate problems as well). Topical rogaine (minoxidil) should work (perhaps not as fast) without side effects seen with propecia. See allergist for treating food allergies & dermatologist for hair loss, which may just be male pattern baldness, not result of food allergies.
