Hi thanks for choosing HCM,
Chronic scaly lesions on the scalp may be either
fungus, psoriasis and
scalp dermatitis.
fungal lesions are spreading type centrally healing and more itchy lesions. Psoriasis are silvery scale lesions with less itching. And scalp dermatitis due to combination of your sweat on scalp, oil and dust.
In your case, it could be Psoriasis..so it is not responding to your fungal treatment.
1) Shampooing of your scalp with Shampoo contains Coal tar,
salicylic acid with other ingredients....alternative days
2)
Betamethasone and salicylic acid lotion..
drops on affected part 3 times daily.
3) For itching...use Levocetrizine daily night.
4)One course of .... Tab
Methotrexate 2.5 mg tablet weekly once with
folic acid tablets for 1 month will give very good results.
Hope this answer will help you.
