GlossaryDiagnosis

identifying a disease or condition based on symptoms and tests

Diagnosis is the process by which a healthcare professional determines the nature and cause of a patient's symptoms and signs. This involves gathering a detailed medical history, conducting a physical examination, and often utilizing diagnostic tests such as blood work, imaging studies, or biopsies. In the context of hair and scalp conditions like alopecia, a diagnosis might include examining the pattern of hair loss, assessing for underlying medical conditions, and possibly performing a scalp biopsy to identify the specific type of alopecia.
