What is a Trichogram?

Trichogram, also known as trichography, involves the microscopic examination of hairs. In this procedure, hairs are plucked, placed in mineral oil, and examined under a microscope. When assessing hairs from an animal with skin or hair coat issues, a veterinary dermatologist can identify evidence of infection, trauma, or hair malformation. Additionally, this method may reveal parasites such as Demodex residing within the hair follicle.
