When two things rub together (like your hair and a hat) electrons can move from one thing to another. Your hair has picked up extra electrons all have the same charge. This causes your hair to repel against each other because like charges repel one another. The furthest any hair can get from another hair is to stand straight up.

Why does my hair stand up when i take off my hat on a cold dry day?

Your hair stands up when you remove your hat in cold, dry weather because of the difference in temperature and humidity. When you wear a hat, it traps heat and moisture close to your scalp, causing your hair to lay flat. Removing the hat exposes your hair to the cooler, drier air, causing it to stand up due to static electricity and the cuticle of the hair strands reacting to the changes in environment.


When you brush or comb your hair vigorously on an extremely dry day your hair strands on end because?

this is due to static electricity building up in your hair when you brush or comb vigorously on a dry day. The friction from the brushing or combing can cause electrons to transfer between your hair strands, creating an imbalance of charge that makes your hair stand up. Using a moisturizing hair product or a humidifier can help reduce static electricity in your hair.

Does your hair curl better overnight when its wet or dry?

Wet Hair or Dry Hair?It is better for your hair to be dry. Why? Well, it depends on where you are, or what you are doing. If you are sleeping with wet hair, that might make you sick. Nothing serious, just a minor cold maybe. For me, having wet hair is uncomforable, but that might be different for you. On a cold day, you might get sick also, though it might cool you down on a hot day. Except on a hot day, it would dry quickly. But who cares anyway? Either way your hair is going to dry. It can't stay wet forever.~ShannonYOU SON OF A 888888888888888888

The static electricity makes the hair stand up:Dry hair in dry weather can absorb and keep a static chargeEach hair has the same charge,Items with the same charge repel each other,Therefore the hairs repel each other resulting in them standing up to be as far from each other as the length and weight of the hair allows.However, if the hair is not dry enough and the air is not dry enough the static charge will leak away and the hair will not stand up.
