I have been suffering from
dandruff for more than 10 years. I have tried Nizoral, coal tar, head and shoulder, selsum blue etc but nothing seems to help.
Especially in 3 area in my head near the centre, I big circle of dandruff forming. They can be almost the size of dime. Its thicken , raised flaky transparent skin layer with dots. I have been noticing this for atleast 4 years now. I scratch and take it out but it rebuilds in just couple of day in the excact location.
