You feel like a new person after stepping out of the salon with your fresh new colour, but after a while your hair can go dry, brittle and dull due to over-processing. Sometimes adding a hair mask to your routine isn’t enough, and so you need a haircare system that treats your hair from within while keeping it vibrant. Damage Undo is a revolutionary breakthrough in bond building haircare, and it’s time to discover how this patented system will keep your hair strong and nourished.

What is Damage Undo?

Damage Undo

Damage Undo is a bond building system featuring six easy to use care products that rebalance your hair, maintain its condition and deliver maximum colour longevity. It uses patented technology to penetrate the hair cuticle, relinking broken disulphide bonds caused by the damaging effects of heat styling and colour, bleaching and chemical treatments while creating the perfect pH balance. Perfect for the everyday haircare routine, it locks in your colour and returns hair to its best condition.

How does Damage Undo work?

The answer is a patented technology called KeraboostTM, created by Damage Undo in collaboration with the Italian Academy of Beauty and Cosmetics. It uses a special blend of vegetable proteins, peptides and fruit acids to naturally protect and relink broken bonds caused by heat, colour and chemical damage. It also rebuilds the cuticle’s outer layer, leaving your hair nourished, strong and shining.

Why should I use Damage Undo?

Damage Undo is an affordable hair bonding system designed to repair and reverse damage caused by a variety of factors including:

• At-home colour treatments
• Perming
• Bleaching treatments
• Heat styling

You can feel the benefits as the KeraboostTM technology relinks and reconstructs broken bonds from within, delivering superior hydration and calming scalp protection while adding a luminous gloss. The system is also 100% vegan and dermatologically tested, meaning you’re contributing to a kinder planet.
