(I threw in the neon afro just for fun)
Their hair almost looks crunchy - like it is actually made of little gold fibers rather than sprayed hair. Reminds me of those costume hair sprays you can get with the glitter in it. In fact, that fourth image actually has little LEDs woven into the silver hair. Brings a whole new appeal to "going gray". I love it. The girls look like gilded statues come to life. Totally unwearable for the real world, imagine putting your shirt on after you get ready in the morning and ending up with a giant streak of gold paint around the neck. But, the effect is nice.
