Curls Be Gone!

Why the hell is it that when you cut your hair dramatically, it curls? For my entire life I've always had very long hair that was completely straight. I recently cut off a foot of it, which of course I regret, and now it wants to curl. Ugh! I want my straight hair back! Time for some extra strength Biotin to get this curly mess to grow faster. If anyone has other ideas, send them my way!
