My sister inherited my mom's beautiful, long stresses, while I inherited my father's excessively dry scalp. I've tried everything to moisturize my dry scalp, even coating my hair in mashed bananas, mayonnaise and egg yolks. One day, my mom suggested that I see a dermatologist about my hair. How can a dermatologist help my scalp? To my surprise, the doctor can. A dermatologist is a skin, hair and nail doctor who offers solutions to numerous problems, including dry scalp. It turns out that I have psoriasis of the scalp. If I didn't do something about the condition now, it'd eventually lead to hair loss and painful sores. If you have hair or skin problems you can't treat alone, please read my blog. A dermatologist can help solve your hair and scalp problems, even if you inherited them.
