DS 9 has been riddled with lice for 3 weeks now. I have tried treatment and spent nearly £100 on various remedies. He has very long, thick surfy hair and it is a nightmare to treat. His teacher has notified me which is mortifying. His childminder said she would get the clippers and shave his hair off (I’m not sure if she was joking). I don’t own any hair cutting equipment but this is seriously taking up so much of my time and causing a lot of stress. What should I do?
