Understanding the Problem: What Is an Itchy Scalp?
An itchy scalp—medically known as scalp pruritus—is a frequent dermatological complaint that can range from mildly annoying to severely distressing.
What It Looks and Feels Like
- Persistent itching or tingling sensation
- Redness or inflammation
- Dry patches, flaking, or visible dandruff
- Occasional small bumps or scabs (from scratching)
Common Causes of an Itchy Scalp
- Dandruff (Seborrheic Dermatitis): Overgrowth of Malassezia yeast, often worsened by oil buildup.
- Dry Scalp: Often due to cold weather, harsh shampoos, or dehydration.
- Psoriasis: Autoimmune condition that leads to thick, scaly patches.
- Contact Dermatitis: Allergic reaction to hair dyes, shampoos, or styling products.
- Head Lice: Tiny parasites that cause intense itching.
- Fungal or Bacterial Infections: Often accompanied by crusting or hair loss.
