A condition of whitening or loss of normal color in hair, resulting in white or gray hair.
From Greek 'achromatos' (colorless) + 'thrix' (hair) + '-ia' (condition). This medical term specifically describes hair that has lost its normal pigmentation, becoming white or gray.
Achromotrichia is the fancy word for what happens when your hair goes gray—your melanocytes stop making melanin in the hair follicles, and the term perfectly captures the biological process of color loss happening in your hair cells!
