Scalp psoriasis is a chronic skin condition characterized by itching and flaking.
What is Scalp Psoriasis?
Scalp psoriasis is a type of psoriasis that affects the scalp, causing red patches covered with thick, silvery scales. It can extend beyond the hairline and affect other areas of the body.
Causes of Itching and Flaking in Scalp Psoriasis
- Genetic Factors: Psoriasis tends to run in families, indicating a genetic predisposition.
- Immune System Dysfunction: Scalp psoriasis is an autoimmune condition where the immune system mistakenly attacks healthy skin cells.
- Skin Cell Turnover: Psoriasis accelerates the skin cell life cycle, causing an overproduction of cells that leads to flaking.
- Environmental Triggers: Stress, infections, and weather changes can aggravate the condition.
- Medications: Certain medications, like beta-blockers and lithium, may trigger or worsen symptoms.
- Other Health Conditions: Disorders like obesity and celiac disease may also contribute to the severity of psoriasis.
- Hormonal Changes: Fluctuations in hormones can lead to flare-ups during puberty or menopause.
