My Dear Welcome to this portal! Your details and concerns have been carefully evaluated and I think that all that you have is Seborrhic Dermatitis of scalp and Telogen effluvium Seb Dermatitis is a mild inflammatory condition in which skin areas with increased density of oil producer glands produce altered skin lubricants and that reflects as flakes on the scalp. Telogen is a disorder, mostly due to unknown causes, that causes diffuse loss of hairs from the scalp. Good treatment options are available for both conditions. 1 For Seborrhic Dermatitis, one can use combinations of Salicylic acid, Ketoconazole, ZPTO that are available in varying combinations. Fora minority of patients, initial use of steroids applied locally does give good start to treatment but please bear in mind that such medications are good only in the early phase and should be discontinued gradually as you recover.Some researchers report that oral Ketoconazole is great help in dandruff cases 2 For Telogen, I would like to suggest taking Biotin tablets. In your case due to coexisting Seborrhic Dermatitis, it is better not to use irritants as they can enhance itching and flakiness caused by the latter condition. You might alos attend more carefully about hair hygiene, regular walks, avoidance of hair cosmetic preparations and improve diet to gain health benefits. I believe this helps you in early recovery. Our best wishes!
