I noticed more hair in my fingers while shampooing, but thought perhaps it was caused by stress, since it coincided with being diagnosed with PD. My hairdresser also noticed some thinning. I attributed the itchy arms and legs to dry skin even though I use a soap for sensitive and dry skin and slather on moisturizing lotion. I didn't really consider medication, but probably should have. You people are terrific - hardly a day goes by without someone giving food for thought here. Judith
