    On average, about 100 strands of hair (from the scalp) fall out per day.
    This is because the hair grows in cycles. Every cycle includes a long growing phase (anywhere up to 7 years) followed by a brief resting phase. At the end of this resting phase, the hair falls out and a new hair starts growing, which begins the whole cycle again.

    • According to Casarett and Doull's Toxicology, Fourth Edition, McGraw-Hill, 1991, page 469, the amount is 70 strands per day. Of course certain chemical exposures can cause this number to increase.
