My sisters girl has nits , should she treat herself also even though

[melsy]

She doesnt have any herself. Ive checked right over and she doesnt have any?????????? Her daughter however has got lyclear 10min cream to use.

Am I right in thinking that if you dont have them , if u use a product you can then make yourself immune, if u do get them, Iykwm lol !! cant explain it!!

Im posting so she can go home now and start on her dd's thick thick long long hair >>>>>> .

Ive been told only to treat if you find lice in the hair. I have never found lyclear to be much good, wet combing every night for a fortnight seems much more effective. We also have a nitty gritty comb which is marvellous.
