Club hair refers to a specific form of hair structure that is often observed in certain diseases or conditions. A club hair is a hair whose shaft is thickened or club-shaped at one end. This feature can be observed under the microscope and often serves as a diagnostic clue in dermatology.
Club hair can occur in various conditions, such as hair adhesion abnormalities, fungal infections of the scalp or specific genetic conditions that affect the hair structure. The change in hair structure to a club-shaped thickening may indicate impaired keratinization or an abnormal growth process of the hair. In some cases, the presence of club hairs may indicate an underlying condition that requires further investigation or treatment.
