Normal Average hair loss per day
Usually it is normal to lose between 80-100 strand of hair per day. If you feel certain activity increases your hair loss, then you can stop doing that activity and see if it makes a difference. Keep track of your hair loss and if it is unusual you consult with a hair loss specialist.
The average person lose 100 hairs per day. If you density is higher, than your daily hair loss will also be higher. I don't think that anything you apply will make a difference.
