Boring, I know, but do headlice/nits ALWAYS cause the scalp to itch?

[notnowbernard]

There have been a few notices about reported headlice at nursery lately

I admit I have never actually PROPERLY checked dd1s hair (have had an examine a few times but not in a rigorous manner) because I've never seen her scratching

Would this always happen, or should I be checking as a mater of course?

(She has A LOT of hair...)

no they don't always cause itching.

Check her hair.

Right. Need to attack then.

HAve just read other headlice thread. Don't know about dd, but MY head is bloody itching now!
