Learn Italian: Non ti sei truccata e non ti sei pettinata. - You didn't put on makeup and you didn't comb your hair.

In Italian, all reflexive verbs (verbs where the action reflects back on the subject, like truccarsi and pettinarsi) use essere as their helping verb in the past tense. Because of this, Italian uses the 'to be' helper verb (sei) instead of the 'to have' helper verb (hai).

Why do truccata and pettinata end in -a?

Because this sentence uses essere as the helping verb, the past participle must match the gender and number of the subject. The -a ending tells us that the person being spoken to ('you') is female. If speaking to a male, it would be Non ti sei truccato e non ti sei pettinato.

What is the rule for the word order with non here?

When making a reflexive verb negative in the past tense, non always goes right before the reflexive pronoun. The unbroken pattern is: Non + reflexive pronoun (ti) + helping verb (sei) + past participle (truccata).

Why aren't there words for 'hair' or 'makeup' in the Italian sentence?

Italian uses specific reflexive verbs for personal grooming. Truccarsi means 'to put makeup on oneself' and pettinarsi means 'to comb one's own hair'. The reflexive pronoun ti ('yourself') handles the fact that it is your own face and hair, so extra nouns aren't needed.
