M25: Looking for shampoo recommendations

As the title suggests, I am looking for shampoo recommendations for regular use. Whenever I used any shampoo other than Head and Shoulders: Smooth and Sily, it causes my hair to become quite greasy almost the next day or within 2 days. Then dandruff, itchy scalp and hair fall follows. Even when I use the Head and Shoulders one, the hair fall is still quite prominent. Hence, I am looking for a shampoo for regular use, which won't be very harsh and can help with hairfall. Thanks!
