I Heard Losing 100 Hairs a Day is a Myth!

hey doc!
i heard that losing 100 hairs a day is normal. i have also read that this is a myth and the correct number is 20-50. can you give some input?

thanks

It is normal to lose 100 to as much as 200 hairs a day. Where are you getting your source of information? Keep in mind that you have somewhere around 100,000 hairs on your scalp. Now let’s do the math. If there are 100 hairs per day lost, multiply that by 365 days, and then triple that number (average hair cycle is 3 years) and you will come close to 100,000 hairs.

That reflects the average hair cycle so the 100 hairs per day lost means that your body is replacing 100 hairs per day at the same time, so that there is a net ZERO hair loss in a person with a hair cycle that lasts 3 years.
