In South Korea, many salons offer a “hair wash service” as part of the package. Clients arrive with greasy, product-laden hair intentionally. The salon wash, with its ten-minute head massage, is considered the highlight of the visit. It’s a ritual, not a chore.
Similarly, in Italy, older women still believe that washing your own hair before a perm is a betrayal of trust. You are messing with the stylist’s canvas. So when in doubt, think like a Roman: trust the artist.
