Well, my hair’s been very long for a couple years now—I trim it myself when I’m able to sit on it, since, y’know, that hurts. It took three or so years for it to grow from my shoulders to my waist, with no special treatment. Just remember:
1. Don’t wash it too often or it’ll get dry, break, and make you sad. Mine’s thick and curly, so once a week is all it needs (hooray!).
2. Don’t process. Lay off on the blow-drying, coloring, and straightening. No, really.
3. Be patient, and don’t bitch too much, unless you want a hair terrorist to shave your head while you sleep.
