[General anime] What the fuck is with everybodies hair?

Everywhere I turn I see people with wacky colors and 7 foot long hair and it seems to just multiply and get bigger the farther from the head it goes.  How is this even possible?

Although the hair styling is more an artistic choice, wacky hairstyles and varied hair color help distinguish otherwise similarly faced characters. This allows production with dozens of artists keep a consistent look rather than attempting to draw varied faces, though it was done in the past, and clearly evolved with the artists responsible as they drew more. 

Hair color is also used to give hints about that characters' personality, as is their eye color. Though what each color means has evolved over time.
