Is the word cabeleireiros the same in Brazilian and European Portuguese?

No. While the spelling and fundamental meaning of the word are identical, there are differences in typical usage and pronunciation.

• Usage: In Brazil, cabeleireiro refers specifically to the professional; to refer to the establishment, Brazilians typically use salão de beleza. In Portugal, the word is frequently used metonymically to refer to the establishment itself (e.g., "Vou ao cabeleireiro" means "I am going to the hairdresser's [shop]").
• Pronunciation: In Brazilian Portuguese, vowels are more open and clearly articulated. In Continental Portuguese, unstressed vowels (like the "e" and "i" in cabeleireiros) are often reduced, closed, or nearly silent.
