Why this is the answer

Trichology is the technical term for the scientific study of hair and its diseases and care. (Dermatology is the study of skin, onychology is the study of nails, and histology is the study of tissues.) Cosmetologists apply trichology when analyzing a client's hair type, condition, and any scalp issues before a service. Knowing the correct '-ology' terms for hair, skin, and nails — trichology, dermatology, and onychology respectively — is commonly tested in the scientific-concepts section.
