Irregular Appearing Scalp

An irregular appearing scalp refers to visible changes in the scalp's normal appearance, including bumps, patches, scaling, discoloration, or texture abnormalities. These changes can range from harmless cosmetic concerns to signs of serious medical conditions. The scalp's visibility varies with hair density, making some irregularities more noticeable than others. Understanding different types of scalp abnormalities, their causes, and associated symptoms helps determine when professional evaluation is needed and guides appropriate treatment.

🚨 Seek Medical Care If You Notice:

Rapidly growing or changing lesions, dark or multicolored spots, bleeding or non-healing sores, severe pain with swelling/fever, spreading redness or infection signs, or scalp masses with neurological symptoms. These may indicate skin cancer, serious infections, or other conditions requiring prompt evaluation.
