seborrhoeic dermatitis

I saw a lady with seborrhoeic dermatitis today. Her persentation is very similar to the following photo:

I thought it is almost time to review the treatment of seborrhoea dermatitis.

1. Cause: unknown. Malassezia is an aetiology factor, hence, the use of anti fungal.
2. Infantile seborrhoeic dermatitis and adult seborrhoea dermatitis are two different conditions.

3. Scalp seborrhoeic dermatitis: treat with anti fungal shampoo or steroid lotion (apply on wet hair and leave overnight and wash it off in the morning)

4. Facial, flexural and scrotal seborrhoeic dermatitis

• Cleansed the skin thoroughly using non soap cleanser daily 
• Apply ketoconazole cream once daily for 2 to 4 weeks 
• Hydrocortisone cream can be used, apply twice daily for 1 - 2 weeks 
• LPC and Tar can be used instead of steroid. 

5. Finally just to remind myself of different classes of topical steroid:
