ONLINE EXCLUSIVE
Damaged hair deserves a complete system — not a compromise. The Milkshake Integrity & Strength 1L brings together the full two-step restorative ritual into one discounted set, exclusively available at Zennkai. Save 10% versus buying each product separately, and commit to the professional-grade repair routine that rebuilds brittle, dull, and heat-stressed hair from the very first wash.
This duo pairs the Integrity & Strength Nourishing Shampoo and Integrity & Strength Nourishing Conditioner — both in 1-litre salon formats — for hair that needs more than a quick fix. Together, they work in a compounding system: the shampoo gently resets and reinforces the strand during cleansing, and the conditioner deeply nourishes, smooths, and rebuilds elasticity in the rinse — leaving hair progressively stronger, softer, and more resilient with every use. Both formulas are paraben-free and the shampoo is sulfate-free, making this a gentle yet powerful daily repair ritual suited to colour-treated hair as well.
What's Included
Step 1 — Milkshake Integrity & Strength Nourishing Shampoo 1L A paraben-free, sulfate-free creamy shampoo that gently cleanses while simultaneously reinforcing dry, damaged, and brittle hair. Organic murumuru butter, argan oil, amaranth seed extract, and Vitamin E work from the first lather to reduce frizz, restore shine, and begin rebuilding elasticity and strength — all without stripping colour or natural moisture.
Step 2 — Milkshake Integrity & Strength Nourishing Conditioner 1L A rich restorative conditioner that completes the repair ritual by deeply hydrating, smoothing, and strengthening compromised strands. Hydrolyzed keratin fills structural gaps in the hair fibre, while murumuru butter seals the cuticle, argan oil restores shine, and lactobacillus ferment supports the scalp's natural microbiome balance. Hair detangles effortlessly and emerges silky, resilient, and visibly restored.
KEY BENEFITS
- Complete restorative ritual in two steps — cleanses, nourishes, and rebuilds in one cohesive system
- 10% savings versus purchasing individually — $149.90 in value for $133.95
- Paraben-free across both products; shampoo also sulfate-free — gentle on damaged strands, scalp, and colour
- Frizz control from shampoo to conditioner — murumuru butter works through both steps for compounding smoothness
- Restores strength and elasticity — amaranth seed extract and hydrolyzed keratin rebuild hair's structural integrity
- Colour-maintaining — sulfate-free cleansing and keratin-rich conditioning protect colour-treated hair
- Progressively healthier hair — consistent use supports long-term resilience, not just a one-wash fix
- Salon-size value — 1 litre of each means fewer reorders and uninterrupted routine consistency
- Sweet tropical fragrance — both products carry the collection's signature coconut, orchid, and vanilla scent
Shared Key Ingredients
| Ingredient | What It Does |
|---|---|
| Organic Murumuru Butter | Deeply nourishes, smooths the cuticle, reduces frizz, and strengthens fragile strands |
| Argan Oil | Restores silky shine, tames frizz, and protects against heat and environmental damage |
| Amaranth Seed Extract | Boosts resilience and elasticity — helps hair withstand styling stress without snapping |
| Tocopherol (Vitamin E) | Antioxidant protection against oxidative stress, UV exposure, and environmental damage |
Â
HOW TO USE: 1) Shampoo - Apply evenly to wet hair, lather from scalp to ends, and massage gently for 1–2 minutes. Rinse thoroughly. Repeat if necessary. 2) Conditioner - Apply to clean, damp lengths and ends. Use a wide-tooth comb to gently detangle. Leave in for 2–3 minutes, then rinse well with cool water. 3) Complete the ritual - For an intensive weekly treatment, leave the conditioner on for up to 5 minutes before rinsing, or follow with the Milkshake Integrity & Strength Intensive Treatment Mask for a deeper repair session.
Pro Tip: The 1-litre duo is the most cost-effective way to commit to a restorative haircare routine. Damaged hair responds best to consistent, regular treatment — having both products in a large format removes the temptation to ration or skip steps between reorders.
