why when you cross the 2 hairs

the moment you try to break them up, you would see like they are "somehow connected", is that "static electric" ?

Not likely... as far as I know, they would both have the same charge if it was a matter of static. If you examine hairs through a microscope, though, you'll see that they are composed of thousands of little scales like the underside of a snake. In your example, I suspect that the scales are catching on each other.

The unique properties of human hair are due to its complex structure and composition. Human hair is made up of a protein called keratin, which is also found in our skin and nails. This protein is arranged in a helical structure, giving hair its strength and flexibility.

When two hairs are crossed or tangled, the keratin fibers from each hair interlock with each other, creating a temporary bond. This is known as the "cohesive force" of hair. This cohesive force is responsible for the difficulty in separating tangled hair and is not due to static electricity.

Static electricity occurs when there is an imbalance of electric charges on the surface of an object. In the case of hair, this can happen when combing or brushing causes friction, leading to a buildup of electrons on the hair's surface. This can cause hair to stand up or stick to other surfaces, but it does not create a bond between two hairs.

The cohesive force of hair is also influenced by other factors such as the level of moisture in the hair and the presence of natural oils and proteins. These can affect the strength and flexibility of the hair fibers, making them more or less likely to interlock with each other.

In conclusion, when two hairs are crossed, the cohesive force of hair is responsible for the temporary bond between them. This is not the same as static electricity and is a result of the unique properties of human hair. Understanding the science behind human hair can help us better care for and style our hair, as well as appreciate its fascinating properties.
