I have something like dundruff near my nose close to chin and also on my eyebrows with dundruff on hair can i get the best treatment?

If you already used: Antidandruff shampoo and did not have any luck , do not waste your time and resource . Get an appointment with dermatologist however difficult it may be and get the right diagnosis and treatment.

Seborrhea : You can use selsun blue shampoo, hand & shoulder dandruff shampoo, tar shampoo, nizorol shampoo. They all work well. It will be your preference. First use three times a week. Also mild Hydrocortisone cream on affected area. If it persists, then see a dermatologist. Thanks.
