I am an African American female close to 51 years old and have been experiencing severe shedding of my natural hair for the past six months. I live in the Dallas area and would appreciate your referral or recommendation of a dermatologist here in North Texas who specializies in African American hair/scalp treatment. I stopped perming my hair in 2004. Recently I've tried various products for my scalp (thinning top crown) and products (shampoos, conditioners & hair cream moisturizers) for my hair purchased at the local beauty supply stores. Most often I wear my hair pulled back with large elastic hair ties or simply wrapped back with a scarf. The only prescribed drug I take daily is for high blood pressure(Norvasc since 2006). Can figure out what's going on. No other female in my family is experiencing hair loss. My mom & three sisters still use chemicals for their hair management. Mom's hair is short but full. My sisters hair is long and full. Not sure how I missed those genes. Thanks in advance for any advice or recommendations you can give.
