Dandruff develops when the scalp’s natural renewal process speeds up, causing dead skin cells to clump together and form visible flakes. It may also be accompanied by itchiness, redness, and irritation. While dandruff isn’t contagious or harmful, it can be bothersome and affect self-confidence.
Key signs of dandruff include white or yellowish flakes on the scalp, hair, or shoulders, an itchy scalp, and sometimes redness or irritation. The severity may vary from mild, occasional flaking to persistent, more noticeable shedding and itching. Symptoms are usually more pronounced in dry or cold weather.
Dandruff can be triggered by several factors, such as dry skin, seborrheic dermatitis, Malassezia yeast, sensitivity to hair care products, stress, and infrequent shampooing. Risk factors include having oily skin, certain medical conditions like Parkinson’s disease, and a family history of dandruff.
Treatment options include medicated shampoos containing zinc pyrithione, selenium sulfide, ketoconazole, or salicylic acid. Regular washing with these shampoos can control flaking and itching. Recovery is gradual, and maintaining a good scalp care routine can help prevent recurrence. Severe cases may require dermatologist consultation.
If over-the-counter shampoos and treatments don’t control the dandruff, or if you experience severe itching, redness, or swelling, consult a dermatologist. Persistent dandruff may indicate seborrheic dermatitis or psoriasis, which require professional care. Seek help if symptoms worsen or interfere with daily life
