Hello dear, History of chronic disease and associated malnutrition is an important causes for hair loss, due to decreased nutrition supply to the hair roots. As you have mentioned in your post that you had Typhoid, it takes time for the body to recover back to its normal state. Management of hair loss includes: 1. Treating the underlying cause 2. Avoidance of stress 3. Dietary modifications 4. Minoxidil solution to be applied locally. 5. Multivitamin & multi mineral supplementation Tugain solution (pharmacologically Minoxidil) will stimulate the hair follicles. Though it may take few months to appreciate the change. So, the medication given by your Dermatologist is right, please use it as advised as hair loss tends to return on stoppage of the medication. You can also include some multivitamin and multi mineral supplement along with it. There is no need to worry. Your hairs will grow back again. Wishing you a Good Health. Take care.
