They have no nerve endings.
Hair, fingernails and toenails, which can be cut without feeling any pain (or sensation of any kind) do not contain nerves, although the roots do contain nerves, so you do feel pain if these are ripped out. Callouses also do not contain nerves.
there are no nerves in hair to transmit any sensation to the brain.
Keratin, the same as your hair and fingernails
Yes, But it is depend on your hair
During a c section, you should not feel any pain, however you will probably feel a tugging and stretching sensation as the doctors pull the baby out
It doesnt hurt when you cut your hair because your hair hasn't any nerve cells so you don't feel anything.
use some standard nail polish remover, it will usually work for any kind of paint/dye that gets on fingernails (or if you get paint in your hair, it works too). Hope this helps :)
You are free to remove hair from any part of your body that you choose. It's your hair, feel free to remove it.
Wash your hair with oilive oil or baby oil. Then, when the hair is saturated, try and slide the paint off your hairs with your fingernails. Then shampoo. This might take you a few nights, but it's not bad on your hair and a ton safer than any other way I know -- and it beats shaving your head :}
If your gums are turning black and have a cold sensation, I would suspect gingivitis or some other form of periodontal disease; in any event, this certainly should be examined by a dentist!
Hair is dead. Only alive at the roots; hence you pull out your hair and it hurts, but you cut it and feel nothing
Because the hair is not living tissue and it doesn't contain any nerve endings. Hair doesn't have any nerve ending, therefore you can't feel it when your hair is being cut.
