The K18 Style Without Limits Set — the repair-and-style routine for hair that is heat-styled regularly and showing it. The Leave-In Molecular Repair Hair Mask to rebuild, HeatBounce to protect under the dryer and iron, and the Molecular Repair Hair Oil to finish, all three carrying K18PEPTIDE™ so every step contributes to the repair.
This set includes:
-
K18 Leave-In Molecular Repair Hair Mask (15 ml) — the four-minute leave-in treatment powered by K18PEPTIDE™, which reconnects the broken keratin chains that colour, bleach, and heat sever.
-
K18 HeatBounce Heat Protectant (47 ml) — the leave-in conditioning heat protectant that detangles, softens, and shields to 450°F with resilicore™ technology, with 85% less breakage after blow-drying.
-
K18 Molecular Repair Hair Oil (10 ml) — the weightless finishing oil that strengthens, reduces frizz at two levels of the fibre, and adds shine without a heavy layer.
The Moda Team Review
The client this set is built for is the one who blow-dries or irons most days, colours every couple of months, and has started to notice that the ends do not hold a curl the way they used to and snap on the brush. Heat is the damage that keeps compounding — every session breaks a few more chains — and a repair product on its own is running up a down escalator if nothing protects the hair the next morning.
This is why the three products belong together. The mask reconnects what is already broken, on the wash day. HeatBounce is the step every morning after: a conditioning heat protectant that shields the cuticle and cortex from the dryer and the iron, so the repair holds. The oil is the finish — a drop on the ends before or after heat that smooths, adds gloss, and defends against the frizz that damaged hair throws off. All three carry K18PEPTIDE™, which means the styling steps are not just protecting the repair; they are adding to it.
At 15 ml the mask is the mid size — roughly two to three months at the maintenance rhythm — and HeatBounce and the oil are travel sizes, which makes this a complete way to trial the K18 system for a heat-styler before committing to full bottles.
Why Moda Carries This
K18 is a biotech haircare brand built on a single foundational technology — the K18PEPTIDE™, a patented bioactive peptide that reconnects broken polypeptide chains inside the hair. We carry K18 as a retail line at Moda because it solves the specific problem of structural hair damage that conditioning products cannot address, and HeatBounce is the heat protectant we recommend most for clients whose hair needs cumulative repair with every styling session, not just a barrier.
Moda Pro Tip
On wash day, the order is mask first, HeatBounce second — never the other way round. The mask needs four minutes of contact with nothing on the hair before it. Once the four minutes are up, HeatBounce goes on top and you blow-dry. On non-wash days, HeatBounce on dry hair before the iron, then a single drop of the oil on the finished ends. Two drops of that oil is too many for anything shorter than mid-back length.
Not the Right Fit If...
Not for someone who air-dries and never uses heat — HeatBounce is the centre of this set, and the So Strong and Clean set is the better K18 gift there. Not for very fine, healthy hair with no colour history; the oil and mask will feel like more than it needs.
