Stress and weight loss linked to telogen effluvium hair loss

Hair loss occurring weeks or months after a period of intense stress, illness, surgery, or significant weight loss may be attributed to a condition known as telogen effluvium. This condition occurs when a trigger temporarily alters the hair growth cycle, causing a larger number of hairs to enter the shedding phase simultaneously.

Dr. Alan Wells, a hair transplant specialist, notes that restrictive diets and rapid weight loss can also act as physiological stressors. Such weight loss can lead to nutritional deficiencies that interfere with the hair cycle.

It is important to distinguish telogen effluvium from other types of alopecia, such as androgenetic alopecia. While telogen effluvium typically causes diffuse and temporary shedding, other forms of hair loss may present with specific, progressive patterns. Medical evaluation of hair density, shedding patterns, and patient history is necessary to determine the exact cause.
