Working with clients symptoms and conditions

I have had THICK hair all my life. Was on WB XL (300mg) for 2 years went off because of memory loss. Was off for 6 months, felt good, but inevitably depression slowly crept back into my life. Went back on WB XL (150mg for a week, then 300mg). Been back on it for 2 1/2 months and just noticed 2 weeks ago that my hairline is thinning at the corners of my forehead. It's especially noticeable when wet or when the light shines down on my head. I can see my scalp. I have also noticed an increase in dandruff. Yikes! I am a hairdresser and it would be terrible for me to have bad hair while working with clients. Why didn't this hair loss happen when I first started taking WB XL 2 years ago? And why is it flarring up now? Is this a temporary side effect that will work itself out, or do I have to stop taking this drug? I'm glad that I am not the only one and that I am not crazy!
