GENERAL HISTOLOGY

Detailed explanation-1: -Physiologically, the epidermis in these parts of the body is very thick and highly keratinized, and when combined with the thick underlaying layer of dermis, this results in skin that does not support the growth and maturation of hair follicles.

Detailed explanation-2: -Hair on your knuckles is completely natural. Whether you have it depends on your genes. There’s no medical reason to remove mid-phalangeal hair, but if you prefer hairless fingers, you can shave, use a depilatory, or wax it off. If you want the effect to last longer, you could try laser hair removal or electrolysis.

Detailed explanation-3: -In fact, it’s actually just a lot like the hair on the rest of your body, which is to say it’s likely genetic. For some reason that scientists have yet to uncover, certain ethnicities are more likely than others to have the gene that causes hair on the hands and knuckles.
