Every person is different. "Not everyone gets these episodes of hair loss. Some women go on and off of contraceptives and never have shedding. Some have seven children and have no hair loss related to it." Once you have shed hair in response to a physiological stress, however, you are likely to do it again, McMichael says.
McMichael says that because people have repeated the myth of a direct connection between emotional stress and hair loss for so many years, many people now believe it. "There's no way to predict who's going to lose hair and who's not. If you're a shedder, you'll shed," Jacob says. She also says there's no scientific evidence that points to specific emotional stresses that might trigger the physical stress that can lead to hair loss.
