Should I Repeat the Treatment Two Weeks After Lice and Nits Are Gone?
A lot of people witness re-infestation after using insecticides or other products. When they first use a product like shampoo or lotion to kill head lice, they notice great results within hours. But, then, after a few days, they notice head lice moving around on their head again.
Whether you use insecticides, non-insecticides or home remedies to kill head lice, you must remember to repeat the same treatment after 7 or 10 days. The reason is that these treatments mostly don’t have any impact on nits. Thus, after a week or so, eggs hatch and re-infestation begins.
So, you must repeat the same treatment after 7 or 10 days to kill newly hatched, blood sucking nymphs (have no mercy… no kidding).
