Stress is indeed related to hair loss. The most common type of hair loss caused by excessive stress is “telogen effluvium.” Mental or physical stress, such as the loss of a loved one, pregnancy, significant weight loss, or surgery, can push a large number of growing hairs into the resting phase. In the following months, you may suddenly lose handfuls of hair while combing or washing it. Once the mental or physical stress subsides, hair usually grows back, but it often takes several months.
For some people, intense stress can also trigger another type of hair loss known as “alopecia areata.” This condition is caused by white blood cells attacking hair follicles, which stops hair growth. In the initial weeks, affected hair typically falls out in small patches. Over time, this can lead to complete hair loss, even body hair. While hair may grow back, alopecia areata can reoccur.
If you notice more hair loss than usual or experience patchy hair loss, it is best to see a doctor. This situation may indicate an underlying condition that needs treatment.
