Pulling on hair can be quite painful but not cutting the hair explain?

Answer 1

When you pull on your hair it hurts your scalp because your hair is connected to it.When you cut your hair it doesn't hurt because your hair doesn't have nerves.When you pull on hair you also stretch it out which can cause you hair to have weak spots.When you cut it you cut it from the bottom so it is still able to grow without damage.

Pulling of hair is pain because hair follicle is surrounded by nerve endings which can detect the movement of pulling of hair. Whereas cutting the hair is just cutting the shaft which is dead, keratinized epithelium, and doesn't have nerves. Therefore this does not hurt.

Answer 2

Hair is not "living" like the rest of your cells. They are extruded (pushed out) from hair follicles. Your hair follicles have nerve endings and blood running to them. When your hair is pulled, the hair is also pulling on the follicle. When you cut your hair, it's just shortening the strands. Since there are no nerves in the hair itself, it doesn't hurt to cut it.

Answer 3

Your hair is actually just waste from your body - it isn't alive. The only part of the hair that's alive is the nerve at the tip. This is why it hurts to pull your hair. The same goes with fingernails and toenails.

Answer 4

Basically there is pain when you pull on hair and nails because they are still attached. It it the body's way of telling you there is danger. Some people do experience pain when their nails are cut, but I have never heard of normal hair hurting when it is cut. If you have knots in your hair and they have been there a while, it can hurt when they are removed if you are not careful. Same is true for matted hair in animals...it hurts because some of the hairs are still attached and perhaps have become infected.
