I have a bald spot from a chemical spill on the left side of my head from when i was a baby. now that i'm older it is kind of showing. how can i fix?

You decide: You can wear a hat, style longish hair to cover it, shave the rest of your hair, decide you like it and tell everybody 'This is where I tipped over a drum of sulfuric acid' or whatever, ask a specialist about hair transplant, and/or give yourself the best gift you possibly can -- focus on fitness (95% of any guy's looks) and being a nice guy and most folks will decide the spot is 'way cool.'
