Dandruff is a common scalp condition causing white flakes of dead skin to shed, often accompanied by itching and irritation. It's usually due to dry skin, sensitivity, or a yeast-like fungus..
Causes of Dandruff
- Malassezia: A fungus that naturally lives on the scalp but can overgrow, leading to irritation and increased skin cell turnover.
- Seborrheic Dermatitis: A common skin condition that causes red, greasy skin covered with flaky white or yellow scales.
- Dry Skin: Dryness of the scalp, which can cause flaking and itching.
- Not Shampooing Enough: Infrequent washing or inadequate rinsing of hair and scalp can lead to a buildup of oils and skin cells.
- Sensitivity to Hair Care Products: Some hair care products or hair dyes may irritate the scalp and trigger dandruff.
- Certain Medical Conditions: Conditions such as psoriasis, eczema, or HIV/AIDS can increase the risk of dandruff.
Symptoms of Dandruff
- White or Yellow Flakes: Flakes of dead skin that may be visible in the hair, on the scalp, or on clothing.
- Itchy Scalp: Irritation and itching, which may worsen with dryness or after using certain hair products.
- Scalp Redness: Mild redness or inflammation of the scalp in some cases.
Diagnosis of Dandruff
Diagnosing dandruff is usually based on the appearance of the scalp and the presence of characteristic symptoms. A healthcare provider may:
- Physical Examination: Examining the scalp and looking for signs of flakes, redness, or inflammation.
- Medical History: Discuss symptoms, hair care routines, and any previous treatments.
- Scalp Analysis: Using a specialized tool or microscope to examine the scalp more closely.

Conclusion
Dandruff is a common scalp condition that can usually be managed with appropriate treatment and self-care. While it may not be curable, symptoms can often be controlled effectively with medicated shampoos, scalp treatments, and adjustments to hair care routines. If over-the-counter treatments are ineffective, or if symptoms worsen or spread to other areas, consulting a healthcare provider may be necessary to explore other treatment options or rule out underlying conditions.
