Homeagain…you are so right. went to dermatologist today. she says it is caused by trauma to body from gbs and subsequent treatment for gbs. she also said the stress is adding to the cause and put me on multivitamins w/o iron. she also sent me for blood work re: thyroid. have to call next week to see what comes back. said no chemicals in hair like color. I highlighted my hair for so many years, that i forgot what it was to be a brunette. Now that i am not blond anymore, i am still not sure what it means to be brunette since there is so much gray!! what kind of hypoallergenics and hair restoratives do you mean? make a suggestion please………….
