For the last few months we have been taken over by headlice and nits! My daughter has very long hair and also ASD with sensory issues so it is an extra nightmare. It started about three months ago and I started off with the NHS guidelines with the conditioner and nit comb on prescribed days. I thought that would be ok. Found nits about a week later after end of treatment! Since then have tried about four different branded treatments following the instructions carefully and following up seven days later. Have just had a phone call from school to say DD is scratching her head and appears to have nits. I can't pick her up as I'm in work and got the distinct impression they're thinking single parent, not caring for daughter etc, receptionist was extremely snotty on the phone. In fairness it touched a nerve as I do now feel like the crappiest mum alive and I'm at my (nit) wits end with the blighters. This is the first time she's ever had them (she's 11). I don't recall nits ever being this much of a problem when I was young, you seemed to apply a treatment and they were gone?? Any advice support would be so gratefully received.
