My son has had nits for ages now which no amount of chemicals, combing or oils has managed to shift.
However, I only had them once and they disappeared quickly never to return.
Eventually, I wondered that it might be because I blow dry my hair every other day and that they were killed off by the hot dry air.
So, I tried it on my son's hair and bingo! it seems to have worked and we have finally got rid of the nits.
Has anyone else tried blow drying them to death?
