Do individuals who have male pattern balding shed terminal hairs?

İndividuals who have male pattern balding do experience  miniaturization of terminal hairs , lack of growth and lenghtening of hair shaft rather than extensive shedding of  terminal hairs.

Do individuals who have male pattern balding shed terminal hairs?Yes, they sure do. In early AGA they shed lots because most hairs on the scalp are terminal hairs. Over time, more and more become miniaturized and vellus hairs - and then this tends to become the main hair shed.

Everyone sheds terminal hairs!  Even those without hair loss.  Hairs are on a cycle of shedding, resting, and growing.  The length of the cycle varies according to body area (brows are shorter than head hair etc.).  
Head hair has a fairly long growth phase, which is why it achieves such length compared to other body areas.  As a male develops pattern loss, those terminal hairs find their growth phase gets shorter and shorter - leading to less robust growth.  The terminal hairs are still going through their cycle of shedding, resting, and then growing, but they are growing less long.
So your question probably stems from the fact that men who bald may notice increased periods of shedding - and their shedding is indeed increased over their baseline - but they would shed normally whether they had male pattern hair loss or not.
Hope that helps!
