Your kids have been back at school a month when the envelope every parent dreads hits your welcome mat: the nits are back (cue frantically scratching yourself all-over).
Looking into the eyes of your precious little one, you just can't possibly believe that their heads could be home to anything more than a hazy-looking halo. But be warned. You're wrong. Lurking beneath that beautiful mop of hair are those nasty little creepy crawlies, head lice.
We think any parent has had their fair share of head lice horrors in their time, and in their own childhoods before that, but never have we seen a case of the nits quite so horrifying as this.
