Does the tip work for everyone?

Dandruff, or seborrheic dermatitis, is a common scalp condition caused by an overgrowth of the yeast Malassezia, leading to flaking and itching. “While regular hair washing can help manage dandruff by removing flakes and reducing oil buildup, the idea of shampooing daily for 21 days is not universally effective. It is important to understand that everyone’s skin is different, and what works for one person may not work for another,” said Dr Sachin Gupta, consultant, dermatology, Amrita Hospital, Faridabad.

Washing or shampooing your hair continuously for 21 days to eliminate dandruff is a temporary solution; your dandruff might eventually worsen over time, said Dr Rinky Kapoor, consultant dermatologist, cosmetic dermatologist and dermato-surgeon, The Esthetic Clinics. “Over-washing your hair can strip away essential oils from your scalp resulting in dryness and itching. Excessively washing hair with chemical-based anti-dandruff shampoo for 21 days can damage your hair making then brittle and frizzy,” said Dr Kapoor.

Then, how to tackle dandruff?

Management of dandruff is done as per the individual’s needs and the severity of the condition. Dr Gupta noted that for mild cases, using anti-dandruff shampoos containing active ingredients like ketoconazole, selenium sulfide, or zinc pyrithione 2-3 times a week can be effective. “For more persistent or severe dandruff, consulting a dermatologist is recommended,” said Dr Gupta.

Dermatologists can provide a comprehensive assessment, rule out other conditions that mimic dandruff, and prescribe stronger treatments like lotions or oral medicines depending on severity.

“Personalised care ensures the most effective and safe management of dandruff, taking into account the unique characteristics of each individual’s scalp and skin,” said Dr Gupta.

A balanced diet and proper hair care practices, can contribute to a healthier scalp and may help address common scalp issues, he added.
