Because there are no nerves in your hair or nails. When you pull on them you are making the hair pull on your scalp, which contains nerves and can thus cause pain. Cutting your hair doesn't touch any nerves, so it doesn't hurt.

Your hair and fingernails do not have nerves, so you can cut or clip them without pain. If you clip your nails back too far, there are nerves in the flesh underneath the nails that can cause pain. The top layers of the epidermis can take shallow cuts and scratches with little to no pain. This layer is very thin. It is what peels off when you get a sunburn.
If you pull a hair, you pull it from your skin, where nerves are located - nerves make you feel pain. On the other hand, hair itself doesn't have nerves
When you pull out one of your hairs from the root, it hurts terribly because there are nerves in each hair root, which allow you to feel pain.
Hair is dead. Only alive at the roots; hence you pull out your hair and it hurts, but you cut it and feel nothing
men pull hair so they can feel like they're the ''MAN'' and the girl is proably a freak and likes it
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.
Hammer nails or pull nails.
To understand this question you need to understand how 'feels': Your hair techniqually is dead, no blood flow goes to it meaning there are no nerves, muscle etc. So if you hair can't percive touch how can you still feel it; it is not the hair feeling it your scaple. When you pull you hair you are lifting up your scaple, and you brian thinks this is not good and 'tells' the neurons, to 'fire up' and start recongizing pain however when you get your hair cut there would be little pain because the blades cut clean meaning they don't tug at the hair. Hope this helps!
