What is Dandruff?

Dandruff is a common scalp condition that leads to flaking and mild itching. While not contagious or harmful, it can be persistent and sometimes embarrassing. Mild cases often improve with regular shampooing, but stubborn dandruff may require medicated treatments.

Symptoms of Dandruff

Common signs include:

·         White or yellow flakes on the scalp, hair, eyebrows, beard, or shoulders

·         Itchy scalp

·         Scaly or crusty patches (especially in infants with cradle cap)

Symptoms often worsen due to:

·         Stress

·         Cold, dry weather

When to See a Doctor

Most cases can be managed with over-the-counter shampoos. However, consult a dermatologist if:

·         Symptoms persist despite treatment

·         The scalp becomes red, swollen, or excessively irritated

What Causes Dandruff?

Possible triggers include:

·         Oily, irritated skin

·         Dry skin

·         Malassezia fungus (a yeast that feeds on scalp oils)

·         Hair product sensitivity (contact dermatitis)

·         Skin conditions like psoriasis or eczema

Risk Factors

While anyone can develop dandruff, some factors increase susceptibility:

·         Age (common in teens and adults, but can occur at any age)

·         Gender (more frequent in men)

·         Medical conditions (Parkinson’s disease, HIV, or weakened immunity)

Treatment & Prevention

·         Regular washing with anti-dandruff shampoos (containing zinc pyrithione, selenium sulfide, or ketoconazole)

·         Moisturizing the scalp to combat dryness

·         Managing stress, which can trigger flare-ups

For persistent cases, a doctor may recommend stronger medicated shampoos or topical treatments.
