What is the main cause of split ends?

Split ends are caused by damage to the hair's protective outer layer, the cuticle, from factors like heat styling, mechanical stress, like brushing, and environmental exposure.

How does the All-in-1 Performer help with split ends?

It has a dual action: it visually treats existing damage by reducing the appearance of split ends, and it helps prevent new ones by sealing the cuticle, strengthening the hair, and providing powerful heat protection up to 230°C/450°F*.

How do I use the All-in-1 Performer in my routine?

Spray it evenly onto damp hair from mid-lengths to ends before styling. You can also mist it on dry hair to make detangling easier and reduce breakage from brushing. Do not rinse.

Is this product safe for colour-treated hair?

Yes, it is safe for colour-treated hair and even helps preserve colour vibrancy as one of its 30 benefits.
