Recently we had a client come in to get treated at our salon, unfortunately for her this was not her first rodeo. She's caught it every year and has been a very loyal customer of ours for a while now, this will be her 3rd time catching lice.
She kept wondering why this always has to happen her, especially since she is in high school now. There are many factors that come into play when it comes to catching lice: sleep overs, airplane rides, sharing clothing, hair-to-hair contact(hugging, selfies, cuddling etc.), public upholstery, and so on.
It can be hard to pin point to where exactly you have caught it.  She said she has been very cautious of everything she does, such as wearing shower caps if she has sleep overs, she even been keeping her hair up, and not sharing brushes.
At this point, it is a mystery to her. Lice happens, and for some it occurs quite often. Rest assured, we are here to help make the mysteries of having lice solved.  HF BG
