Selsun Suspension, which contains 2.5% selenium sulfide, is generally used to treat dandruff and certain scalp fungal infections. For children around 8 years old, it is important to be cautious.

• Age Consideration: This medication is usually recommended for adults and children over 12 years old. For an 8-year-old, you should consult a pediatrician before use.
• Safety: Children's skin can be more sensitive, and selenium sulfide may cause irritation or other side effects if not used correctly.
• Alternatives: There are gentler shampoos and treatments designed specifically for children that might be safer options.
• Recommendation: Always follow a doctor’s advice before applying this product to a child’s scalp. If irritation, redness, or worsening symptoms occur, stop use and seek medical attention promptly.

Consult a pediatric dermatologist or your child's doctor to determine the safest and most effective treatment.
