Perms

Perms often involve the use of chemicals that break and reform your hair to create a new shape of your hair. Your hair is washed and wrapped on a perm rod. This solution creates a chemical reaction that softens the inner structure of the hair by breaking some of the cross links within and between the protein chains of the hair. The hair swells, stretches and softens, then molds around the shape of the perm rod.

Curly vs. Straight Hair

The way your hair looks is mainly because of your parents. The big reason it looks the way it does is because of genes coming from your parents, passed down from their parents and so on. Besides genetics, curly hair has a lot to do with your follicle, especially the shape of it. A person with curly hair would have a long oval shaped follicle that basically has a "hook" at the end of it. The sharper the hook the more curly your hair will be. Obviously is you have straight hair you will not have a "hook" at the end of your hair.

Ever Wonder Why Your Hair Turns Grey?

As you get older, so does your hair. Getting gray, silver, or white hair is a natural part of growing older. The main reason for your hair changing color is beacuase each hair has a follice that contains pigments. The pigments in your hair contain melanin, which gives the shaft of your hair its color. As we get older the pigments in our hair gradually die and stop producing melanin, which causes your hair to lose color and turn gray or even white.
