There's no such thing as "hair science", I've found, beyond a few very rudimentary rules that generally apply to all hair across the board and pertain to very basic chemistry and physics.

I took off a year as an undergrad, thinking it'd be fun to attend cosmetology school. My annoying questions (along the lines of actual science) largely went unanswered, or at times one of the teachers would give a half-hearted fib to try and fill in the knowledge gap with something other than dead air.
