Little muscles at the base of each hair shaft called arrector pili (also Erector pili).
When we are cold, muscles just below our skin, called erector muscles, contract. This pulls on our hairs, causing them to stand on end. By doing this, the hairs form an insulating layer of air, which keeps us warm and maintans our constant internal body temperature.
When an animal feels cold it puffs up its fur in order to create air pockets which act as insulation. Humans have hair that is too short to be effective in this manner but the nervous system still responds in the same manner to the sensation of coldness.
A smooth muscle, the arrector pili, attaches to the follicle in such a way that contraction of the muscle causes the hair to stand on end. If a person
has had a scare or is cold, "goose bumps" develop due to contraction
of these muscles.

no its because when its cold you get goosebumps

Straightners work by breaking down the hairs hydrogen bands found in the hairs cortex, which causes hair to bend and curl. Once the binds are broken, hair is prevented from holding its original and natural form.
Fragilitas Crinium is commonly known as split ends. It is when the hair becomes brittle and breaks, leaving it frizzy. It is caused by any factor that causes the hair to dry out and lose moisture such as chemical treatments, sun, wind, and chlorine pools.
Fragilitis crinium or split ends are caused by dry or brittle hair. Harsh chemical treatments or a lack of proper conditioning can lead to split ends.
The so called fly away hair effect of electrostatics is when every single hair on your body stands up. It is mostly seen at the top of the head where the hair is longer. This is caused by the ionization of the hair surfaces when your body accumulates a static charge. As electrons are driven off into the air, each of the hairs assumes the same charge and they repel each other. This is more apparent in cold, dry weather when there are fewer water molecules in the air (these block the ionization). Read the articles in the Related Links for more information.
The arrector pili muscles makes the hairs on your arm stand on end.
Static Electricity generator an electrical force can make your hair stand on end that happens because, your hair has picked up extra electrons. This causes your hair to repel against each other(Like charges repel remember!). Because you hair is so tightly packed, the furthest any hair can get from another hair is to stand straight up.
If you have goosebumps
To make someone's hair stand on end is to cause them to be very frightened, the expression is derived from getting goosebumps when scared and thus having your hair stand on end.
An arrector pili is any of a group of small muscles attached to hair follicles in mammals, the contraction of which causes the hairs to stand on end.
Rub your head with a rubber balloon. Then you will see your hair stand on end because the static electricity in it causes each hair strand to repel every other strand.
