I switched to wellbutrin about 6 mo. ago and have noticed crazy hair lose... it is on my pillow in the morning, on the sofa after watching t.v., on the back of my shirt, and coming out by the handfulls when shampooing or brushing my hair. What use to be a full, thick head of hair... is now so thin I don't always brush my hair everyday (makes me sick to see all the hair). I talked to my dr. about it and she said it must be my blood sugar and that I needed to lose weight for it to go away.... um, yeah... eating low carb, walking, and still losing just as much hair... I am giving her a call today after reading that HAIR LOSS IS A SIDE EFFECT!
