Can Adderall Cause Greasy Hair?

Can adderall cause Greasy hair. Lately I ve been thinking spiders are on me, I m perscribed adderall xr 10 mg but I ve been taking about 4 of them, is that bad? Also I ve been noticing a weird smell on me. Only when I take it though, my mom told me she kept smelling a chemical smell but I was a little too embarrassed to say it was me. Could someone explain this for me? What s going on with my body?
