We've learned before that the negation particles ne... pas go around the verb:
Vous ne lavezpas la table.
You don't wash the table.
When the verb is reflexive, the reflexive pronoun me, te, se... goes inside the ne... pas sandwich like this:
Je neme lavepas les mains.
I don't wash my hands.
Vous nevous lavezpas les mains.
You don't wash your hands.
The order of the words don't change when using the negative forms
ne...jamais and ne...plus
Je nem'achètejamais de livres.
Je neme laveplus les cheveux le soir.
