I took Wellbutrin XL 6bvyears ago and experienced weight loss but no other side effects. I recently started again. At the same time, I had the keratin protein treatment that make my curly hair straight. Recently, i noticed a lot of hair loss. I been attributing this to the hair treatment, but when I went to an acupuncturist about hair loss, he immediately said it was the wellbutrin. I couldn't believe it!!! 2 different doctors told me hair loss was not a side effect of Wellbutrin XL (300mg). But after the visit to the acupuncturist, I did a little more digging and found this sight. I can't believe what I'm reading. This wasn't my experience in the past when I took the drug. I will definitely stop this med ASAP. Good luck to you all.
