What Should I Do?
The most important thing to do is to find out what's causing your hair to fall out, and for this, you'll probably need to see your doctor. It's best to do this as soon as possible so you can start getting your hair back and feeling more confident.
In the mean time, check this list of hair-loss causes:
- Reactions to certain medications
- Hormone imbalances
- Pregnancy (although hopefully this isn't the case if you're thirteen!)
Good luck, and don't let it bring you down. If you're feeling self-conscious, perhaps you could get yourself a cute hat - I have a friend who is never seen without a beret because her hair's quite thin, but she's really made it her 'look'. It's worth a try, if nothing else!
