I thought up until now that Dermatologists handled problems affecting the hair and scalp?
This is true in many instances. However, 90% of the patients that Trichologists see are nutritionally deficient, while others suffer thyroid imbalance and still others are challenged with medication. The hair responds like a barometer for the body. When hair is shedding it is like a red light for a Trichologists, indicating something internally is out of balance.
