does stress cause hair loss?
Stress-Induced Hair Loss. Some amount of hair loss is normal â strands fall out over time and get replaced by new ones. However, when youâre under physical or emotional stress the normal shedding of 100 or so hairs a day can speed up to the point where half to three-quarters of your hair can fall out. Known as telogen effluvium, this diffuse and often stress-induced hair loss may not happen right away.
