Why do scalp wounds bleed profusely but heal rapidly?

-because it's rich in blood supply.

-firstly, the dense connective tissue layer contains a large number of blood vessels with rich blood supply.

if the scalp is but the dense connective tissue surrounding the vessels tends to hold cut blood vessels open. as a result profuse bleeding happens. (ref. gray's anatomy for students 2nd edition. page 873)

-as profuse bleeding will occur, it will bring more and more clotting factors. so, it will heal rapidly.
