A few hair tips I have picked up since boarding:

1. Only condition the ends of your hair, this will prevent it from becoming oily really quickly. 
2. To prevent frizzing, after you have washed your hair and dried it, rub moisturiser on your legs and then rub the excess on the ends of your hair. Do this by scrunching your hair with moisturiser.
3. Use organic shampoo and conditioner. I recommend the brand Alchemy.
4. Rub coconut oil on the roots of your hair, leave for 10 minutes, then wash it off with shampoo followed by conditioner. This makes your hair really healthy.
