Summary Introduction
To review:
The reason behind no sensation of pain during hair cutting.
Introduction:
Hairs or pilli are flexible strands generated by hair follicles. They are composed of cells. Although they play a major role in keeping mammals warm, in case of humans, their function is less useful. The major function of hair in humans is to sense the presence of insects on the skin prior to their sting or bite.
