The entire body is covered in hair follicles. While in the womb, you grow and shed hair from every part of your body. This happens twice.
So now that we have a baseline that the entire body is covered in hair, we can look a bit deeper.
The ear tab just before the opening varies by gender. After 2nd puberty (around 25) the male ear grows a hair "bud" that's a cluster of hair follicles. This is also the time that the male chin starts to change into it's adult form.
If you lightly scrape the inside of the tab, you should be able to feel the hair bud.
Without a genetic malfunction, women should not have hair buds. However, it is possible to grow ear hair through a-gendered hair follicles on the ear.
I didn't know about 2nd puberty! Is there a third?
