After removing the PBE, which action helps remove residual oxygen from the hair?

Explanation:
After removing the PBE, some oxygen can remain trapped in the hair. The most effective way to release that gas is to run your fingers through the hair or give a light shake to loosen and vent the trapped air. This direct motion helps evacuate the residual oxygen from the hair quickly. Rinsing with water doesn’t target the trapped gas, brushing doesn’t actively vent gas from the hair, and moving the head side to side addresses pressure changes rather than removing gas from the hair.
