This strange piece of advice could end up saving lives in the event of nuclear war.
In the event that a nuclear bomb is dropped, make sure to avoid using conditioner when washing your hair.
This is because conditioners have certain molecules called cationic surfactants, which can end up trapping radioactive particles inside your hair
Moreover, conditioner is meant to linger on your hair, so anything stuck to the conditioner will also remain, causing even more damage.
While conditioning might do a lot more harm than good, simply shampooing your hair will wash these harmful particles right out.
As North Korea continues to threaten an attack and with many believing the country is close to having nuclear missiles, tensions in nearby countries are high.
