Caucasians come in all skin colours. Google it.
Caucasoid is the actual terminology, and from what I've noticed, all caucasoids bald at the same rate, whether white or brown, Indian, Mediterranean, middle eastern ect. I live in an area with lots of Chinese and noticed that they thin later in life but hits them hard past 40. The women don't fare any better than the men.
My father in law is Slovak and is a norwood 1 at 85 years old. And he's white. My boss is 63 and dutch and a norwood one. A coworker of mine is 65 and a norwood 0.
Not many men in my immediate family, but my father was balding in his 30s. I didn't start until my late 40s. I'm white anglo
