The Matrix Instacure Build-A-Bond Holiday Duo is a limited-edition 2026 gift box with Matrix's bond-repair shampoo and conditioner for very damaged hair, both in full 300 ml sizes.
Inside the box:
- Instacure Build-A-Bond Shampoo (Mighty Bonds), 10.1 oz (300 ml)
- Instacure Build-A-Bond Conditioner (Mighty Care), 10.1 oz (300 ml)
Both formulas use citric acid to strengthen the hair from within and squalane to soften and smooth the surface. The shampoo is sulfate-free and cleanses gently while helping repair weakened bonds. The conditioner nourishes from mid-lengths to ends without weighing hair down.
Matrix reports hair up to 8x stronger and 94% smoother when the full Build-A-Bond system is used (shampoo, conditioner, liquid mask and leave-in balm, compared with a non-conditioning shampoo). The mask and balm are sold separately, so this duo is the everyday base of that routine. In a consumer test, 83% said their hair felt revived after one use. The range is suitable for colour-treated and highlighted hair.
A practical gift for anyone dealing with breakage and split ends from bleaching, colour or heat styling.
