Welcome to healthcare magic.
is a chronic problem which can have remissions and relapses. With treatment, the lesions can completely disappear and can recur after weeks to months of stopping treatment.
For the current episode, use a lotion containing 4.25% coal tar
with 2% salicylic acid
in a shampoo base to wash your hair. You need to keep the lotion in contact with the scalp for 15 minutes and then rinse off with water. Use a lotion containing 0.05% clobetasol propionate
with 3% salicylic acid at bedtime everyday for 2 weeks. This will resolve the lesions. For maintainence ( to prevent recurrence), continue to use the shampoo alternate days for at least 3 months.
You may still get one or two new patches. Use the bedtime lotion for 2-3 days as soon as you notice a new patch before it becomes bigger.
Hope this helps you.
If you have any further queries , I will be glad to assist.
