Greetings... There are multiple causes for hairfall during this particular age. Before jumping to treatment,we should try to find out the cause..most common causes  could be genetic as per your family history of baldness, thyroid hormonal imbalance, stress related issues.. Blood tests to be done to rule out above causes.. Use mild shampoo which are sulphate free. 2-3 times shampooing per week is sufficient. Take iron rich food like green leaves, pomegranate etc For the new hair growth, minoxidil 5% lotion 1 ml to be applied morning n night over the scalp and gentle massage to be done.. Results varies between individuals
