Scalp problems are a common issue that can range from LICE, DANDRUFF, and SCURF. LICE are tiny parasitic insects that feed on human blood and can cause itching and irritation. DANDRUFF is a condition of the scalp that causes white flakes of dead skin to appear in the hair and on clothing. SCURF is a type of skin condition that causes dry, flaky patches of skin to form on the scalp. All of these scalp problems can be treated with proper hygiene and medical treatments.
