Is your dandruff like a greasy dandruff, or what? Dandruff is caused by either dry scalp, build up of chemicals, or a condition called pityriasis. Is is a greasy dandruff or what? If it is it could be pityriasis. (Sore-eye-a-sis) If that is the case than you will have to go to the doctor and get medication. If it is just dry scalp than yes t-gel will work, or you can dry applying sea breeze to your scalp and rub it in. If it is shampoo build up than you can get a stripping shampoo, or just simple mix your everyday shampoo with baking soda and make a paste. hope that helps
