I am mortified. We got rid of head lice just before the lockdown and probably gave up the combing before we should have done. I've just looked through my DDs hair and found that she has loads, more than she had the first time round, and DS had them too. I've treated with the Full Marks I had left from last time and combed about 3 times with a nitty gritty. Is there anything I can do to stop them coming back, other than the obvious of not stupidly stopping before I should? Neither of my DC can tolerate the nitty gritty comb for long periods. DD has long, thick (but thankfully, straight) hair and she gets quite upset when I comb it. What can I do to stop hurting her? I feel dreadful and I'm horrified I haven't picked up on it earlier.
