1. What is Selsun shampoo?
Selsun shampoo contains selenium sulfide, an antifungal and anti-seborrhoeic agent used to treat dandruff, seborrhoeic dermatitis, and certain fungal skin infections. It helps reduce scalp flaking, itching, and inflammation.
2. What conditions does Selsun treat?
It is commonly used for dandruff and seborrhoeic dermatitis of the scalp. It is also effective for tinea versicolor, a superficial fungal infection that causes discoloured patches on the skin.
3. How does selenium sulfide work?
Selenium sulfide reduces the growth of Malassezia yeast on the skin and slows down excessive skin cell turnover. This dual action helps decrease flaking, scaling, and irritation.
4. How should Selsun shampoo be used?
The shampoo should be applied to wet hair or affected skin, massaged into a lather, and left in place for several minutes before rinsing thoroughly. It is typically used two to three times per week initially, then less frequently for maintenance once symptoms improve.
5. How long does it take to see results?
Improvement in itching and flaking is often noticed within one to two weeks. For tinea versicolor, skin colour changes may persist for weeks to months after the infection has cleared.
6. Are there any side effects?
Selsun is generally well tolerated. Possible side effects include scalp irritation, dryness, oiliness, temporary hair discoloration, or an unusual hair texture. Allergic reactions are rare but possible.
7. Can Selsun be used on the body?
Yes, for tinea versicolor, it may be applied to affected skin areas as directed by a healthcare professional. It should be rinsed thoroughly and avoided near the eyes and mucous membranes.
8. Is Selsun safe for regular long-term use?
It can be used intermittently for maintenance of dandruff or seborrhoeic dermatitis. Long-term frequent use should be guided by a healthcare professional, especially if symptoms persist.
9. Who should avoid Selsun shampoo?
Individuals with a known allergy to selenium sulfide should avoid its use. It should not be applied to broken or inflamed skin unless advised by a healthcare professional.
10. When should I seek medical advice?
Medical review is recommended if symptoms do not improve after several weeks of treatment, worsen, spread, or if there are signs of infection such as increased redness, swelling, or pain.
