MICROANATOMY

Detailed explanation-1: -There’s no other way to say it: human hair is strange. Compared to most other mammals, human beings are decidedly naked, and the little fuzz that we do have is oddly patchy and quite diverse. The most obvious of our bizarre bald regions are perhaps the soles of our feet and the palms of our hands.

Detailed explanation-2: -Hair grows all over the human body except the palms of the hands, soles of the feet, and lips.

Detailed explanation-3: -Hairless skin like palms and soles contains a natural inhibitor that blocks the WNT signalling pathway. The lack of or no hair on our palms and soles sets us apart from other mammals.
