Not tested on animals

Information Icon

Since 2013, animal testing for cosmetic products and their ingredients has been prohibited by law in the EU – and that's a good thing. But for us, that's not enough: we are actively campaigning for these standards to apply worldwide and to be enforced.

That's why we only work with partners who share the same values – for responsible hair care that does not involve animal suffering.

Application step

Cleanse

The first step on the way to healthy-looking hair: cleansing removes residue, excess oil, and styling product build-up from the hair and scalp. Only on clean hair can conditioning ingredients work deeply, styling products take effect properly, and finishes reveal their full potential.

Care

Care moisturizes the hair, strengthens the hair structure, and protects against external influences. This keeps the hair supple, color-intensive, and resilient. A well-cared-for hair base is essential—it makes all the difference in styling and durability.

Style

Every look starts with the right shape: styling adds structure, volume, or smoothness to the hair—just as you wish. At the same time, it protects against heat and friction and adds texture or shine. The three hold levels make selection easy and ensure lasting results.

Finish

The final step completes every look. Whether you want natural bounce or maximum control, finishing products set your style, protect your hair, and add shine. Depending on the hold level, your hairstyle will remain flexible, retain its shape, or stay completely in place—all day long.
