K18 Damage Repair Service Set puts the K18 step of a colour or chemical service in one box. It is meant for use in the salon and holds the Molecular Repair Hair Mist in 300 ml and the Leave-In Molecular Repair Hair Mask in 150 ml. The mist goes on wet hair before the service starts, and the mask closes it, 1 to 3 pumps as the finish.

Key ingredients

The mask, from its ingredient list

• sh-Oligopeptide-78: 9th on the list
• Hydrolyzed Wheat Protein: 10th, wheat-derived
• Hydrolyzed Wheat Starch: 11th, wheat-derived

What to expect

Two moments inside one service, not an extra appointment. The brand says the mist works against split ends; its own directions give it 4 minutes before the bleach or colour. In that time it cares for and strengthens the hair, and the brand presents it as protection against chemical damage before colouring or bleaching. The mask cares for and strengthens damaged hair, with better elasticity and less breakage.

Who it is for

• Salons adding a K18 step to colour, bleach or other chemical services.
• Colourists who want the pre-service mist and the finishing mask as one order.

Who it is not for

• Home use: the set is meant for use in the salon, during a colour or chemical service.
• Anyone sensitive to the fragrance allergens on the mask's list: Geraniol, Linalool, Hexyl Cinnamal and Benzyl Alcohol.
• Anyone avoiding wheat-derived ingredients: Hydrolyzed Wheat Protein and Hydrolyzed Wheat Starch are on the mask's list.

How to use

The set's own six steps as published, translated from Dutch. Each product's own directions sit on its own page. Our tip for long or thick hair: use more, smaller sections for the mist.

Method A: the set's six steps

1. Apply the Molecular Repair Hair Mist (300 ml) to wet hair, before the colour or chemical service.
2. Leave the mist on for four minutes. Do not rinse.
3. Then carry on with the colour or chemical service as usual.
4. Wash the hair after the service and pat it dry.
5. Apply 1 to 3 pumps of the Molecular Repair Hair Mask (150 ml) as a finish.
6. Leave the mask on for four minutes as well. Do not rinse. Then cut or style.

Where it fits in the K18 range

In the set's list of contents the mist is also called Molecular Repair Spray; it is the same product. The mist is listed alone as the K18 Molecular Repair Hair Mist 150 ml, and comes in 30 and 300 ml as well. The mask in this set is the K18 Leave-In Molecular Repair Hair Mask 150 ml.
