DS has had nits a number of times since starting school, and after only being able to get the lice out and his hair being infested with eggs i splashed out the £10 on the Nitty Gritty comb yesterday. It works wonders!!! Makes the £3.99 one ive been using look useless! BUT its a SOD to clean!!! If i run my nails through the teeth will i make the spirally bits blunt? Anyone have any suggestions on how to clean this wonderful thing?
