Are you going bald? Bald already? Don't like your hairline? Never fear, nanobots are here!
Nanobots can be applied to areas where hair growth is non-existant and completely regenerate hair growth by stimulating hair follicles. This would spell the end of baldness forever. For those of you with a big forehead, this technique could even be used to change your hair line.
Maybe you already have hair, but want to grow your hair quickly for that wedding next month. Apply some nanobot hair stimulator! Grow a centimeter of hair every day.
Or maybe you want to quickly grow a husky moustache for that porn convention next week? Hey, who am I to judge?
