Hi Piya You seem to have telogen effluvium .you are right.... There may be some cause....like anaemia,vitamin and nutritional deficiencies,thyroid dysfunction, stress, anxiety,worries,travelling,any other internal disease,certain drugs.... ..etc. Poor hygiene and poor nutrition may be responsible for telogen effluvium. You consult dermatologist for firm diagnosis. To controll hair fall and to improve hair growth you may take biotin 10 tab daily for few months and apply mild steroid lotion on scalp at night daily. For dandruff use anti dandruff shampoo containing ketoconazole. For hair oiling and shampoo use herbal preparations. Take treatment for few years. Have patience..for the good result. I hope this would help you. Thanks. Dr. Ilyas Patel MD
