Most studies have shown that mechanical removal alone (ie, wet-combing every 2-3 days for a minimum of 2 weeks) is not as effective as mechanical removal combined with a pediculicide. [57] Proper treatment with medication is advised.

Shaving is effective but is usually not necessary or socially acceptable. However, in resistant disease, it may be a consideration.
