13.9 Shampoos and other preparations for scalp and hair conditions
- Dandruff is considered a mild form of seborrhoeic dermatitis.
- Shampoos containing antimicrobial agents such as pyrithione zinc and selenium sulfide (which are widely available) may have beneficial effects.
- Ketoconazole should be considered for more persistent or severe dandruff or for seborrhoeic dermatitis of the scalp.
- Corticosteroid gels and lotions can also be used.
- Shampoos containing coal tar and salicylic acid may also be useful.
- Patients who do not respond to these treatments may need to be referred to exclude the possibility of other skin conditions.

- Shampoo should be left on the scalp for 20-30 minutes before washing off.
- Ketoconazole shampoo is often helpful for seborrhoeic dermatitis of the scalp.
- Eucerin® shampoo (which contains urea 5%) can be particularly useful for elderly patients with very dry scalp.
Sebco® and Capasal® contain coconut oil; caution should be used if nut allergy is a co-morbidity.
