No, cutting your hair should not hurt if done properly with sharp scissors or clippers. If you experience pain while cutting your hair, you may be cutting too closely to the skin or pulling on the hair too forcefully.
It doesn't produce the same outcome because your skin has sensors and blood vessels underneath to trigger more cell production to heal the wound. Hair is different. It doesn't have any blood vessels on it so it can't bleed. Nails wont bleed but if you cut them too short and rip or puncture the skin it can happen. Hopefully this helps
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.
Because as hair is formed, it matures through a process called "keratinization", that's when the hair cells lose their nuclei. Once a cell loses its nucleus, it's no longer alive, so by the time the hair emerges from the skin, it is merely dead strands of protein. Also same with nails. == Cutting hair or nails doesn't hurt because there are no nerve endings. You can shave yourself bald or keep your nails very short. The only time you may hurt your fingers while cutting nails is if you go up into the nail bed.
Nails are dead skin cells.
The hair that shows above your skin is composed of dead cells made up of a tough protein called keratin; toenails and fingernails are also made of keratin. So hair and nails have no feeling above the surface of your skin. They are alive below the skin, though, where their roots are attached to nerves. That is why it hurts when someone pulls your hair: they are tugging at live roots. But having your hair and nails cut doesn't hurt at all.
Teeth. Skin, hair and nails are all formed from a layer called the dermis.
Teeth do not belong because they are not made of the same protein (keratin) as skin, hair, and nails.

There are cells in the epidermis (outer layer of the skin) which are alive and as they fill with keratin, they "push" forward and so the hair and the nails "grow". This appearance of growing is actually a sign that the cells at the skin are growing. The hair and the nails are dead. They can be cut as there is no feeling in them. If a person cuts the nails too short, that will hurt and bleed. See link below:
