Imagine a colour with the sophistication of forged metal: Gems 18 Iron is a dark, cool shade with metallic undertones reminiscent of polished steel or burnished iron.
What is Gems 18 Iron
Gems 18 Iron is a semi-permanent toning mask from the CODE ZERO Gems Collection. Its ammonia-free, ready-to-use formula deposits direct pigments for a dark, metallic grey with cool, magnetic depth. No oxidiser is required and the colour fades gradually after a few washes, letting you experiment without long-term commitment.
Who it is for
Ideal for anyone seeking a dark, metallic colour with sophisticated shine and cool reflections, whether toning pre-lightened hair or adding depth to natural hair. Gentle enough for sensitised hair, and suitable for professional use in the salon and for confident at-home application.

How to use
- Wash the hair beforehand and towel-dry to remove excess water.
- On natural, untreated hair, apply the mask evenly throughout, leaving on 5 to 15 minutes for a subtle tint or an intense reflection.
- On pre-lightened or highlighted hair, leave on 15-20 minutes for a deeper, longer-lasting effect.
- Distribute with a comb for a uniform result without pigment buildup.
- Add a little lukewarm water and gently massage to emulsify, then rinse thoroughly until the water runs clear, avoiding shampoo to preserve the deposited pigments.
