What’s inside — and why it’s there
The ingredients worth knowing.
- Shine polymers — create an ultra-smooth cuticle surface that maximises light reflection. IQHC — blocks humidity to maintain the shine finish rather than having it dulled by the first damp conditions.
Reviews
Questions? We get them.
Good to know.
The questions we hear most about this product. If yours isn’t here, a real stylist will answer.
Ask ModaIs the High-Shine Gloss a rinse-out or leave-in?
Leave-in — apply to damp hair after conditioning and blow-dry as normal. Don’t rinse.
How often should I use it?
As needed — it’s an intensive shine treatment, not an everyday step. Once or twice a week delivers the best results without over-conditioning.
Does it work if I air-dry?
It adds some softness, but the full glass-finish gloss result requires a blow-dryer to activate.
Is it suitable for fine hair?
Yes — apply sparingly from mid-lengths to ends and keep off the root.
Is it colour-safe?
Yes.
