L60-L75: Disorders of skin appendages
L67: Hair colour and hair shaft abnormalities
Hair colour and hair shaft abnormalities make up a group of conditions that impact the production, structure, and colouration of hair. These conditions can be innate, meaning they are present from birth, or they can develop over time due to various factors such as nutritional deficiencies, hormonal imbalances, autoimmune diseases, or exposure to certain medications or harmful chemicals. Abnormalities in hair colour can range from unusual shades (like graying at a young age) to patches of pigmentation. Hair shaft abnormalities, on the other hand, refer to structural changes that affect the hair's texture, strength, and growth, leading to fragile, thin, or excessively curly hair. This group of conditions doesn't typically cause other physical symptoms, but it may have psychological effects due to the changes in appearance. Progression and specific effects depend on the underlying cause and the particular type of abnormality.
