How much hair loss is normal for women?

According to WebMD, average hair loss for women and men consists of 50 to 100 strands per day. Washing the hair can cause a woman to lose up to 250 strands in a day.

Hair loss in women typically manifests in a part that grows wider over time or the visibility of more scalp than usual when pulling hair back in a ponytail. Women often see hair loss on the top half of the scalp, with the front hairline staying in place. Other signs of hair loss include strands of hair left on a pillow each morning or finding more hair than normal in a hairbrush or a comb.
