The One HEAD SPA — An Immersive Hair & Scalp Ritual

A deeply restorative ritual

Designed to reset the scalp and transform the hair, The One HEAD SPA blends advanced ultrasonic technology with personalised care to restore balance at the root, where truly healthy hair begins.

Why It Matters

Pollution, product build-up and daily stress disrupt the scalp long before the hair shows signs.

This ritual restores clarity, hydration and strength at the source, creating the conditions for smoother, stronger, more luminous hair.

The Ritual

Personalised Diagnosis
A detailed scalp and hair analysis guides a fully tailored treatment.
Ultrasonic Mist Therapy
A fine, weightless mist prepares the scalp and hair to absorb active ingredients more effectively, without heaviness or stress.
Bespoke Treatment
A purifying cleanse is followed by a customised mask, enhanced with targeted Boosters selected for your hair’s specific needs.
Thermal & Scalp Therapy
Gentle warmth enhances absorption. A cooling phase seals the cuticle. A therapeutic scalp massage relieves tension and stimulates circulation.
Signature Finish
A Gielly Green blow-dry reveals hair that feels lighter, stronger and visibly radiant.
