Dandruff affecting the scalp, eyelids, and the area behind the ears is commonly caused by Seborrheic Dermatitis, a condition linked to oily skin, irritation, and overgrowth of natural skin yeast. It can cause white or yellow flakes, itching, redness, and dryness, especially around oily areas of the body such as the scalp, eyebrows, eyelids, sides of the nose, and behind the ears. Symptoms are often more noticeable in the morning because flakes collect overnight. Treatment usually includes regular use of anti-dandruff shampoos containing ketoconazole, zinc pyrithione, or selenium sulfide, which help reduce fungal growth and scaling on the scalp. The shampoo should generally be left on the scalp for a few minutes before washing for better effect. Gentle cleaning of the eyelids and behind the ears with mild soap or warm water may also help remove flakes and oil buildup. Avoid scratching the affected areas because it can worsen irritation and lead to infection. Stress, poor sleep, excessive sweating, and harsh hair products can sometimes make dandruff worse, so maintaining good hygiene and a healthy lifestyle may help control symptoms. If the itching becomes severe, the skin becomes very red, swollen, painful, or the dandruff does not improve with regular treatment, you should consult a dermatologist because stronger medicated lotions or creams may be needed. With regular care and treatment, most people are able to control dandruff and reduce flare-ups effectively over time.

For an 8‑year‑old, Selsun Suspension should only be used if prescribed by a paediatrician or dermatologist, who can determine if it’s appropriate for the child’s condition. Do not use it without professional guidance, as children can be more sensitive to irritation. It should be applied externally to the scalp only, following the healthcare professional’s instructions.
