Each Hair is in a different phase. Our hair grows (Anagen), rests (Catagen) & then falls out (Telogen). Everyone's growth phase is different. It all comes down to genetics. That is why some people can grow hair to their shoulders & some can grow hair to their butts.
This growth phase lasts 3-6 years. This will shorten as we get older. (sad face)
Hair grows super slow, 1/4 - 1/2 inch a month, so when a hair falls out it will take a full year to get 6 inches.
This is why we need to be good to our hair & even better to our scalp.
So when it comes to shedding time, there are 6 - 8% of our hairs in this phase on our head. We shed 50 - 100 hairs per day. These hairs will have a hard white bulb on the end of the hair shaft. This bulb means that the hair was ready to come out & was in the Telogen phase. This is normal shedding; however, if you feel that you have more than 100 per day, you might have Telogen Effluvium. I have another blog about this.
If you see hairs that are coming out & do not have the white bulb than you are pulling them out before they are ready. Be careful! Us fine Haired people need to keep every hair we have. Right?
