Shaggy Hair for Pet Rocks
Born in 1975, an era that had no shortage of long shaggy hairstyles, pet rocks tend to look best in this type of hair. You could fashion miniature wigs out of natural fibers to keep your rock's look updated, or you could paste the hair directly onto the rock for a more permanent hairstyle. The androgynous glam-rock look featured by David Bowie in his Ziggy Stardust era lends a touch of glamor to a rock with musical tendencies.
Punk Rock Pet Rocks
An easy type of hairstyle that gives any pet rock attitude is the mohawk. One way to create a mohawk for your pet rock is with stiff construction paper, felt or foam that you cut into spikes. This can then be attached with a small band to the top of the rock's surface. For a real punk rock look, you could use bright colors such as hot pink or magenta.
Pet Rock Mullets
Although the mullet hairstyle is seen as being ironic by some, or as a throwback to the 1980s, it can help remind pet rocks of their rebellious youth. A mullet is characterized by being cut short in the front and long in the back. This can be crafted from synthetic fibers, but natural hair will give a softer look and feel to your pet rock.
Facial Hair for Pet Rocks
The types of hairstyles described above can help liven up the top and sides of a pet rock, but rocks may also benefit from patches of facial hair. Small felt or bristle beards and moustaches can be pasted onto the surface of the rock's face. These can be kept groomed with doll combs, or left bushy and wild for a tough biker mountain man look that befits a pet rock with a strong personality.
