Q: My husband is 26 years old and often works late into the night. He used to have thick hair, but now it’s thinning, especially on the crown, and his hair is soft and yellowish. What condition could this be, and how should it be treated?
A: This is seborrheic alopecia, which is related to genetics. As for the connection with staying up late, no one has reported on that yet.
