To alleviate itchiness from lice, what action is recommended?

Using medicated shampoo is the recommended action to alleviate itchiness from lice. Medicated shampoos typically contain active ingredients designed to kill lice and their eggs, effectively addressing the underlying cause of the itchiness rather than just the symptom. This approach not only offers relief from itching but also helps prevent further infestation, promoting scalp health and comfort.

Other options, such as rubbing the scalp vigorously, might irritate the skin further and could worsen the itchiness without addressing the infestation. Ignoring the problem can lead to increased discomfort and spread of lice, while wearing hats frequently does not treat the issue and may even trap lice and eggs against the scalp, prolonging the infestation.
