What's French for 'nit shampoo'?

[twilightcafe]

On holiday in Brittany and noticed that DD was head-scratching more than usual.
Looked in her hair - and she has nits.
Do French supermarkets have nit combs/shampoo, or should I try a pharmacist?

Shampooing anti-poux

Anti-poux. You need to go to the pharmacist and ask for it, it is behind the counter.

Go to the pharmacie. You need to ask for quelque chose pour traiter les poux de tête

Or just go in and mime scratching your head furiously

Thank you, everyone! I have the nit treatment and comb, so will set to de-nitting DD.
Nothing else to do, seeing as it's pouring with rain today .
