Its been around 3-4 months but i ignored it assuming it as a normal dandruff which might wash away. Now its becoming more critical with large patches & scabs of dry dandruffs spreading all over the scalp head. Though i have been using herbal shampoo & oil of BIOTIQUE yet its not been removed till yet, instead the condition has become worst & when i start scratching or itching on head the dandruff starts droping in particles from the patches. Please suggest me some immediate tablets & remedies.
