Your history is consistent with a diagnosis of 'Seborrheic Dermatitis
'. This is a condition where the body loses tolerance for a yeast called Malassezia (which is present normally on all our skins) and starts attacking it leading to redness and scaling. Itching is variable but can be severe.
The highest concentrations of the yeast responsible are present in the scalp and face (especially the sides of and below the nose, eyelids and the area around the eyes, central part of the face including eyebrows and behind the ears) so these are the sites most frequently affected. They may be involved singly or in combination. Here is what will help
1. 1% Cortizone cream + 2% Miconazole cream: Mix and apply twice a day for 14 days over the affected area on the face. Then once at night for 4 weeks.
2. Nizoral-AD shampoo: apply and leave for 5 minutes on the scalp after working up a lather. Do this every alternate day. (e.g Mon-Wed-Fri). Use regularly for 4-6 weeks then start decreasing the frequency of application gradually till you reach once a week and maintain.
This should also take care of the scalp itching.
3. Tab Claritin 10 mg morning and evening for 10-14 days.
4. Cap Lumitene (Beta Carotene) one morning and evening for 1 month. This is an excellent anti-oxidant and decreases the inflammation associated with this condition.
5. Tab Biotin 5 mg - morning and evening for 3 months.
NOTE: All of the above are available without a prescription. Steps 4 & 5 though non essential, will help prevent a recurrence of the condition. Hope this helps!
