Is alopecia and hair loss different?

Answer 1

They are at the same time the same thing and different it depends on the degree and cause. We are losing and regrowing hair all the time. Hair loss that doesn't grow back can be a natural process especially of men as they age commonly thought of as male pattern baldness. Alopecia on the other hand often has a cause but it isn't clearly understood but is usually thought of as a autoimmune disease where the body attacks its own hair follicles. And there is some indications that stress if a factor as well.
