Hi,
You should follow a well balanced weight reduction diet, which contains good quality protein, fresh fruits and vegetables. Include milk, dahi/ yoghurt, paneer, soyabean, cashew, almond, mixed sprouts etc as a source of protein. As you are doing work from home, obviously your activity level becomes less, resulting weight gain. To maintain weight, with following diet, you need to do exercise in regular basis. There are many reasons behind hair fall, if it's deficiency of protein or micro nutrients it can be rectified by above mentioned diet, otherwise it will be better to consult with dermatologist.
