Why Do Head Lice Keep Coming Back?
A common complaint we hear from distraught people calling in seeking advice is that the head lice keeps reoccurring despite their best efforts which leaves them wondering what they have been doing wrong and how they can get rid of lice for good. The truth is, that for many reasons lice treatment can fail which is why the lice keeps coming back.
LICE TREATMENT DIDN'T WORK
A common reason that lice keep coming back after treatments is that the treatment did not work. This does not necessarily mean that you performed the treatment incorrectly. Lice have developed a resistance to chemicals, often rendering these products ineffective. If the bugs are not killed by the treatment, they will lay more nits (lice eggs) so nits keep coming back as well.
SOMEONE ELSE GAVE LICE BACK TO YOU

Another reason that head lice keep coming back is that someone keeps giving it to you. Often, the source of the infestation is not the person you think it is, so if the main culprit is not treated, others who spend time with her or him in close proximity will get a case of head lice over and over. This is why it is very important that everyone in the household is checked and treated at the same time. Don’t assume family members don’t have it just because they are not itching. While it also may be uncomfortable, we recommend advising families whom you or your children have been around so they can be checked and treated as well if necessary.
What To Do When Lice Keeps Coming Back
If you are wondering why does lice keep coming back after treatment, you’re not alone.
TRY NITPICKING
No matter what treatment you use to kill lice, if you don’t get the nits out you’ll be wondering why do lice keep coming back. The impermeable eggshells don’t allow topical treatments inside. Even prescriptions cannot kill 100% of the eggs.
TREATING THE WHOLE FAMILY

By the time scratching starts, the whole family has been exposed for weeks. Only treating people with visible lice is one of the main things what causes lice to keep coming back.
FIND MORE EFFECTIVE TREATMENT BECAUSE IT DIDN'T WORK
Head lice keeps coming back because most treatments just don’t work. Successful methods address the entire life cycle – killing or removing bugs, then combing and hand-picking every egg out of the hair.
HAVE A FOLLOW-UP TREATMENT
Why do nits keep coming back, even when the bugs are gone? They’re not new nits, they’ve just grown mature enough to see. Successful lice treatment needs some kind of aftercare.
