Answer 1

Asian hair is so thick, because East Asian hair cuticles are much thicker and hair diameter is much more in size. Even though Asian hair types normally have fewer hair, the thickness of their hair shafts creates the impression of a fuller head of hair. It’s also pretty rare to see a bald Asian as they experience less shedding of hair.
