Lice can return after treatment if any eggs (nits) were left behind, as they can hatch and lead to a reinfestation. Additionally, lice can easily spread from person to person through close contact or shared personal items like hats, brushes, or bedding. If someone in the household or close environment has lice, it increases the likelihood of re-exposure. It's essential to follow up with thorough combing and cleaning to ensure complete elimination.
Only if you are re-infected will it come back.
You say he is gone when you do not expect him to come back.

Mommy lice

No it will not come back because its gone for a long time
to be honest I do not know. But all I know is that it may be bad, for your hair and the lice will not go away. But if it does then problem solved. But if they come back 2-3 weeks later from the eggs that were in your hair then you will have to use lice treaments
spray infected areas with soapy water
Read the back of the lice treatment box. :-/
If all the lice is gone then yes. Just don't shair hair stuff and putting on hairspray prevents from getting lice.
