Why can’t we feel our hair growing?

Heads up! Your hair is always growing. Like your fingernails, hair is a part of our body that will grow and grow unless you cut it. But how come we don’t feel it growing? We asked pediatrician Dr Wendy Hunter to help us find the answer. Got a question that has you tearing your hair out? Send it to us at BrainsOn.org/contact, and we’ll help comb through research for the answer. See omnystudio.com/listener for privacy information.
