There are many reasons why hair stands up. The scientific name for this is “piloerection.”
One reason is that the piloerector muscles near the hair follicles contract, which makes the hairs stand up. This might happen when someone is cold, scared, or excited.
Another reason is that the sebaceous glands near the hair follicles produce more oil when the hair stands up. This makes the hair look shinier and also helps to keep it waterproof.
The third reason is that the hairs might curl up when they stand up. This happens because the outer layer of the hair, called the cuticle, has tiny scales that overlap. When the hair stands up, the scales curl together, which makes the hair look curly.

What happens when your hair stands up outside?
Hair standing up outside is a common phenomenon that can happen to anyone. It is usually accompanied by a sensation of tingling or pins and needles in the scalp.
When the hair stands up, it is usually because the individual is feeling cold or scared. The hair stands up as a way of trapping air around the scalp, which helps to keep the head warm.
In some cases, the hair may also stand up when a person is feeling excited or happy. This is because the body releases adrenaline in response to these emotions, which can cause the hair to stand up.
While the hair standing up outside is generally not a cause for concern, it can sometimes be a sign of a more serious condition. If the pins and needles sensation is accompanied by pain, weakness, or numbness, then it may be a sign of a neurological disorder.
If you are experiencing any of these symptoms, it is important to see a doctor as soon as possible.
Why does my hair not fall down?
There are many reasons why hair might not fall down. One possibility is that the hair is too short. When hair is too short, the individual strands are unable to hang down naturally because they lack the length to do so. Another possibility is that the hair is too dry. When hair is too dry, it is unable to hold onto moisture, which is necessary for it to hang down properly. Another possibility is that the hair is weighed down by products. When hair is weighed down by products, it is unable to hang down naturally. Finally, another possibility is that the hair is damaged. When hair is damaged, it is unable to hang down properly because the damage can cause the individual strands to be weak and break easily.
Why does hair stick up when cold?
There are a few reasons why hair stands up when it’s cold outside.
The most common reason is that cold air contracts and causes the tiny pockets of air inside the hair shaft to shrink. This causes the hair to stand up, as it’s trying to trap more heat close to the scalp.
Another reason is that when the body is cold, it sends more blood flow to the core to keep the vital organs warm. This can cause the scalp and hair to get a bit lighter in color, as there is less blood flowing to the surface. The lighter color makes the hair shaft more visible, and makes the hair stand up more.
Finally, some people believe that the hair can stand up when it’s cold because the cold air causes the sebum (oil) on the scalp to solidify. This could make the hair stand up a bit more, as the sebum would be less likely to spread evenly over the hair shaft.
Regardless of the reason, most people’s hair will stand up when it’s cold outside!
