How Do You Know If You Lose 100 Hairs A Day?

Hi Doctor, you say that one lose on average 100 hairs each day. On what basis you say that? is it based on a scientific research and finding or just your own guess based on average number of hairs on someone’s head and the percentage of hair in telogen phase and length of the latter. If any of these parameters is in fact different, which is likely to be, then your assumption will not be accurate or correct. Thank you for all

The 100 hair loss a day has been widely published and accepted as the normal shedding of hair. Also note that it is not actually 100 hairs a day everyday, but “UP TO” 100 hairs a day.

If you take in to account that our hairs are also growing in cycles or telogen (resting), anagen (growth), catagen (transition) phases 100 hair loss a day out of 100,000 hairs is 0.1% of your total hair count. Also take into account while you are losing 100 hairs there are likely another 100 hairs that are starting their anagen (growth).

Anagen phase in measured in years, telogen phase in measured in months so more hair is actually in the growth phase in a normal cycle.

There are always exceptions to the rule, and not everyone is the same.
