La Sereine Head Spa

What the hands actually do. Technique reads every mention of the scalp work itself: skill, pressure, tool use, and the range of ritual on the menu. It scores how consistently guests report precise, practiced work.

The setting, taken seriously. Sanctuary reads what guests say about the room itself: how quiet it stays, how carefully it is kept, and whether the calm holds for the whole visit rather than just the photos.

Did it work? Efficacy tracks whether guests report the result they came for after the ritual, not just during it: tension relief, better sleep, a calmer scalp, healthier hair.

Everything around the treatment. Hospitality scores the visit end to end: how easy it is to book, how clearly the spa communicates, and how guests are received, guided, and sent home.

Reported alongside the rating, never averaged into it. Hygiene reads reviews for the care of tools, linens, and practice; a complaint here surfaces as a visible flag rather than a quiet point deduction.

Also reported alongside the rating. Value weighs what guests say the experience is worth against what it costs, so a fair-priced gem and a spotless but overpriced room are never smoothed into one number.
