A Dermatologist is a medical doctor who treats skin disorders internally, as well as externally. A dermatologist diagnosis and treats skin diseases, as well as the scalp. Everything is done from a medical standpoint.

A Trichologist; however, provides services from a holistic perspective, taking into account the mental, physical and social factors, rather than just physical symptoms of the disorder.

Keep in mind, a Certified Trichologist can work in conjunction with a Dermatologist, or a medical doctor.
