Hair loss is a sign associated with Acute Radiation Syndrome.

Hair loss occurs because hair follicle cells are among the most rapidly dividing cells in the body, making them highly sensitive to ionizing radiation. In Acute Radiation Syndrome, whole‑body exposure damages these actively renewing cells in the hair follicle, causing the hairs to shed as the follicles lose their ability to produce new hair. This loss typically appears after a dose sufficient to produce systemic damage, so hair loss is a recognizable sign associated with ARS alongside other acute effects on rapidly dividing tissues. It’s an acute somatic effect of radiation, not a genetic change, and it reflects the sensitivity of the follicular tissue rather than any resistance. So hair loss being related to radiation aligns with how ARS affects tissues with high cell turnover.
