A craft built
over years.
- Holistic Nutritionist & Wellbeing Strategist
- Architect of the Miss Yu scalp-first method
- Champion of UV-filtered water rituals
Sonja's background sits at the intersection of holistic nutrition, wellbeing strategy, and quiet hospitality. She has spent years studying how rest, water quality, and ritual shape the way we feel — and how the scalp, often overlooked, sits at the centre of all three.
She co-founded Miss Yu Hair Bar to translate that thinking into a hair destination. From the UV-filtered water at every wash station to the calming tea served between steps, every detail of the guest experience carries her signature.
Sonja leads the Treatment Bar philosophy and the Miss Yu Method — Diagnose, Purify, Restore, Refine — ensuring each visit feels like wellbeing, not just maintenance.
