Adderall hair loss?

I started taking Adderall 10mg XR 3 years ago. I only take it 3x/week.

I just came across pictures from 3 years ago and I can't believe how much my hair has thinned out compared to how it looked 3 years ago.

Is 10mg 3x/wk really enough to cause hair loss? Nothing else has changed in my routine or meds.
