Trichology is a branch of dermatology focused on the scientific study of the hair and scalp. A Certified Trichologist (WTS) is a trained specialist who can help determine the underlying cause(s) of hair loss and scalp issues. They can recommend effective treatment options.

Trichology is a paramedical field, much like a nutritionist, therefore trichologists often work with other medical professionals when additional testing or prescriptions are needed.
