Lots of hair loss in 2009 - which made washing my hair very unpleasant. I take biotin (a supplement) and use a brand of shampoo and conditioner which, I read, was originally created for cancer patients. It seems to be correcting itself this year. From everything I read, unless you have a specific condition, stress and medication related hair loss is reversible when the stressful situation or medication is changed.
As far as the grey goes.....I say the Serenity Prayer and hit the salon once a month
I noticed strands of grey in my hair while I was in my 20s before AXBF was in my life.
