The actions you describe could just be habits that she will outgrow, but they could also be compulsive behaviors. When people have compulsive behaviors, they are driven to do things because they feel they have to, or because it makes them feel better (usually only briefly). They may want to stop doing them, but they can't.

If the behaviors are habits, you may be able to lessen them. You can help her be aware of them and give her positive feedback for not doing them. For example, praise her when she stops herself from chewing her hair. Perhaps she might earn a prize or treat for going a day (or half day, whatever is manageable) without pulling on her eyelashes.

If this doesn't work, talk to your doctor about a referral to a mental health professional.
