Eating disorders can change hair. I know this isn't really an eating disorder but I have anemia. My hair was really dry and frizzy. On top of all I am very depressed. My parents are not supportive at all either! They just act like it's normal to feel "sad" but they don't know the difference between "sad" and "depression". My mom is the even bigger ignorant fool. All she cares about more than my depression is cleaning and her dumb plants. I've been battling depression for 3-4 years. My hair keeps breaking off and has been the same length for 4 years. I put olive oil and two eggs in my hair and my hair looks way better. To think that the fact that my hair looks dryer than before I had depression and that I am always sleeping my parents would think for once. But try olive oil and egg.
