According to the American Academy of Dermatologists, it is normal to lose anywhere from 50 to 100 strands of hair per day. Hair shedding is part of the natural hair renewal cycle, and each hair follicle goes through a cycle that includes a growth stage (anagen) and a rest stage (telogen) before the hair falls out. Hair with plenty of volume, movement, and shine is what most people consider healthy. Women tend to lose more hair strands per day than men, but there is no objective way to measure the difference because daily heat styling and frequent hair coloring play a big part in how much hair sheds. If you notice that you are losing much more hair than you usually do, you should see a doctor to help determine the cause.
