Oh, Biology.

A certain amino acid by the name of Cysteine has a Sulphur-Hydrogen side-group at the tip of its R-chain (being the side chain that isn't the primary Amine or Carboxyl group). Under certain conditions (oxidation, specifically), two of these R-groups may connect, emitting a water molecule and forming a covalent bond between two sulphur atoms.

These bonds are called Disulphide bridges... or SS Bonds.

SS.

Apparently people whose hair is curlier simply have more SS bonds in their hair keratines - the amino acids that form them form SS bonds more readily.

... In other words, my hair is a Nazi.

... The fact my last name is Deutsch makes things even more lol. >>;;

HEIL CYSTEINE!

... I swear that Cell to Organism lectures make me feel instantly better. >>;
