FAQ

Are the formulas colour-safe?

Yes — every formula is sulfate-free and pH-balanced to keep colour molecules where they belong.

Is the packaging really glass?

Amber glass bottles and jars with recyclable pumps. Refill pouches are on the roadmap for early next year.

Which products should I start with?

Start with the base: No. 01, No. 03, and No. 06. If your hair is coloured or heat-styled, add No. 04.

How long does a bottle last?

Washing three times a week, the 250 ml bottles last about three months.

Do you test on animals?

Never. Ondine is Leaping Bunny certified.
