Scalp Disorders: Diagnosis and Treatment for Common Scalp Problems

Understanding Scalp Disorders and Common Scalp Problems

Your scalp is skin, and like the skin on your face or body, it can develop irritation, inflammation, infection, growths, and chronic medical conditions. Many people search for help with scalp problems such as itching, flakes, bumps, sores, scabs, burning, tenderness, or hair shedding without realizing these symptoms may be signs of an underlying medical issue.

Because the scalp also supports your hair follicles, scalp health directly affects hair growth. Some scalp problems are mild and temporary, while others can lead to thinning or permanent hair loss if not diagnosed and treated early.

At Aglow Dermatology, we help patients understand the cause of their scalp symptoms and create treatment plans that protect both scalp health and hair growth.

  • Itching and scalp flakes
  • Scalp scabs or sores
  • Burning, pain, or tenderness
  • Pimples or acne on the scalp
  • Redness or rash
  • Dryness or excessive oiliness
  • Patchy hair loss or shedding
  • Thick scale or crusting
  • Scalp infection or drainage
  • Lumps, bumps, cysts, or growths on the scalp

Common Types of Scalp Problems

Dandruff and Seborrheic Dermatitis

Many people think they simply have dandruff when they actually have seborrheic dermatitis, a common inflammatory condition that causes flakes, itching, redness, and greasy scale.

Scalp Psoriasis

Scalp psoriasis can cause thick scale, itching, scalp scabs, and inflammation that may affect comfort and hair growth. It is often confused with severe dandruff.

Folliculitis and Acne on the Scalp

Painful bumps, pustules, and “zits on the scalp” are often forms of folliculitis, which is inflammation of the hair follicles. This can be caused by bacteria, yeast, irritation, or inflammatory conditions.

Some deeper inflammatory conditions, such as folliculitis decalvans or dissecting cellulitis, can lead to scarring and permanent hair loss.

Scalp Infections and Ringworm

Scalp infections may be caused by bacteria, yeast, or fungus. Tinea capitis, also called scalp ringworm, can cause flakes, broken hairs, scalp sores, and patchy hair loss.

These infections are often mistaken for dandruff or eczema and may require prescription treatment.

Contact Dermatitis and Scalp Allergies

Hair dye, relaxers, braids, fragrances, shampoos, and styling products can all trigger scalp irritation or allergic reactions.

This may cause itching, rash, burning, tenderness, peeling, or scalp sores.

Cysts, Lipomas, and Other Scalp Growths

Not all scalp problems are rashes or inflammation. Many patients develop lumps or bumps on the scalp such as cysts, lipomas, large moles, skin tags, or other benign skin growths.

Pilar cysts and epidermoid cysts are especially common on the scalp and may become tender, inflamed, or uncomfortable when brushing hair or sleeping. Lipomas are soft fatty growths under the skin that can become noticeable or bothersome over time.

Some patients also notice larger moles, seborrheic keratoses, or other growths on the scalp that may need evaluation to determine whether they are benign or should be removed.

Scalp Problems and Hair Loss

Scalp inflammation and hair loss often happen together.

Conditions such as seborrheic dermatitis, psoriasis, folliculitis, lupus, CCCA, and other forms of scarring alopecia can damage the scalp and affect hair growth.

Sometimes patients focus on hair thinning when the real issue begins with scalp inflammation.

Other Skin Conditions That Can Affect the Scalp

Many skin diseases that affect other parts of the body can also affect the scalp.

This includes:

  • Eczema
  • Lupus
  • Psoriasis
  • Fungal infections
  • Allergic rashes
  • Autoimmune conditions
  • Skin cancer

Because the scalp is hidden by hair, skin cancer and suspicious growths may go unnoticed for a long time. Painful sores, bleeding spots, non-healing lesions, or changing moles on the scalp should always be evaluated by a dermatologist.

When to See a Dermatologist for Scalp Problems

You should see a dermatologist if you have:

  • Persistent itching or flakes
  • Scalp scabs or sores
  • Burning or painful scalp symptoms
  • Hair shedding with inflammation
  • Scalp acne or folliculitis
  • Patchy hair loss
  • Symptoms that do not improve with over-the-counter products
  • Lumps, cysts, lipomas, or changing growths on the scalp

Early diagnosis is especially important when scalp inflammation may lead to permanent hair loss or when a scalp growth needs further evaluation.

Frequently Asked Questions About Scalp Problems

Scalp scabs may be caused by psoriasis, seborrheic dermatitis, folliculitis, fungal infections, eczema, allergic reactions, or scratching due to severe itching. Persistent scalp scabs should be evaluated by a dermatologist.
