I am suffering from severe dandruff since past 10 years. I am 29 years male living in Delhi. I consulted a dermatologist 4 yes back and he prescribed noskurf lotion to be applied overnight and to be washed with protar-k shampoo in the morning. Situation improved then but was back within 2 months. I don't understand whether it is just dandruff or seborrheic dermatitis. I have also been losing hair and lost almost 50% of my hair in last 5 years. Please suggest a treatment for this irritating dandruff and increasing hairfall.
