There are many things I've learned growing my hair out, but these are the most important:

1. One of the best things you can do is keep your hair in a bun or a braid as much as possible. The less opportunity it has to tangle, the less likely it is to break, and it helps protect the ends. I keep it up most of the time out of necessity at this point - my hair is hip-length and I'm constantly sitting on it if I leave it down.
   
   
2. A good detangler is important. My stylist recommended this a few years ago and I bought a bottle from the salon for $20. I only use a couple of drops after every wash in my hip-length hair, and I'm still on my first bottle (though it's almost empty - I just bought a new bottle). It keeps my hair super soft and shiny and untangled on the rare occasions I leave it down.
   
   
3. These are my favorite hair accessory. After a little practice, it only takes three of these and five minutes and my hair is in a bulletproof bun and ready for any situation. And that bun will last until I pull the pins out - I've fallen asleep with my hair up and woken up with it still in the exact same style (if a bit frizzy).
