2. Psoriasis: When the Immune System Overreacts
Scalp psoriasis is an autoimmune condition that causes the body to produce skin cells too quickly. This leads to thick, red, scaly patches that may itch intensely.
Common symptoms include:
- Thick scales on the scalp
- Red inflamed skin
- Itching and burning
- Bleeding caused by scratching
Stress is known to trigger or worsen psoriasis flare-ups in many people.
