I am about to turn 23 (so of course I haven't gone bald yet). I have really thick black, wavy hair. My mom's dad is bald and went bald pretty young. My dad started going bald around 40 and his brother is pretty bald. My mom's brother has a really thick head of hair at 51 and his grandfather (my mom's mom's father) had a really full head of hair too. With that info what are the chances of me going bald? Is there any way to prevent it? Also, my dad's dad has a really full head of hair at 79.
