Our Story

Ondine began with a question: why does hair behave differently in different water?

The answer — minerals, pH, and everything we layer on top — became a formulation philosophy. Every Ondine formula is balanced to the pH of healthy water (4.5–5.5), built from cold-pressed oils, silk proteins and marine minerals, and stripped of everything that exists only to foam, thicken or perfume.

Eight essentials. Nothing more.

We make one shampoo for every day and one for reset days. One conditioner. Two treatments. Three finishers. That is the whole pharmacy — numbered, in amber glass, designed to be used up and refilled.

What we leave out

Sulfates, silicones, drying alcohols, synthetic dyes. Nothing in an Ondine bottle interrupts the work of the formula before it.

— Formulated in California. Bottled in amber glass. Never tested on animals.
