An itchy scalp is a common problem and can range from mild irritation to a sign of an underlying condition. Understanding the cause is key to proper treatment.
🧴 Main Causes of an Itchy Scalp

- Common in cold weather or with frequent shampooing.
- Usually improves with hydrating shampoos or oils.
3️⃣ Psoriasis
- Thick, red patches covered with silvery scales.
