The water is too hot.
Stress 'CAL-da'. 'Acqua' = AK-kwa.
Say this immediately at the washbasin if the water temperature is uncomfortable. Italian stylists always ask about temperature preference but may miss the mark.
'Troppo calda' = too hot (feminine to agree with 'acqua'). Temperature vocabulary: 'calda' (hot), 'fredda' (cold), 'tiepida' (lukewarm), 'giusta' (just right). The washbasin station ('postazione lavaggio') always has adjustable temperature.
L'acqua è troppo fredda.
The water is too cold.
For cold water.
Può regolare la temperatura?
Can you adjust the temperature?
Polite request.
Così è perfetta, grazie.
Like this it's perfect, thank you.
Confirming it's right.
Italian hairdressers are trained to give a 'massaggio capillare' (scalp massage) during the shampoo, which is considered an integral part of the service. Many Italian clients say the scalp massage is their favourite part of the salon visit — 'il massaggio alla testa è meraviglioso'.
