The final step in a bond repair routine is the one most people skip — and it's the one that determines how long the results last. Milkshake Everlasting Bonds Leave-In Treatment is designed to be exactly that: the protective, strengthening finish that seals in what the shampoo and conditioner repaired, extends the bond-building results between washes, and shields hair from the heat styling that re-damages what you've just fixed. The lightweight formula is built on the patent-pending NutriBond Complex™ — an exclusive blend of rice proteins, amino acids, Hyaluronic Acid, and Glycosaminoglycans enhanced by Hydrolyzed Milk Protein — that supports the hair's internal structure, maintains bond strength over time, and leaves hair visibly smoother, softer, and more resilient with every application. Heat protection runs to 230°C / 446°F, making it a functional dual-purpose leave-in for anyone who heat styles regularly.
What It Is
A lightweight leave-in treatment that seals bond repair, smooths, and protects hair from heat styling up to 230°C / 446°F. Patent-pending NutriBond Complex™ (rice proteins, amino acids, Hyaluronic Acid, Glycosaminoglycans) supports the hair's internal structure for stronger, healthier-looking hair with every use. Apply to towel-dried or dry hair. Do not rinse. Paraben-free.

- Breakage
- Frizz
- Color-Treated
Key Benefits
- Seals and extends bond repair results between washes — when used as the final step after Everlasting Bonds Shampoo and Conditioner, the NutriBond Complex™ maintains the structural repair achieved during cleansing and conditioning, preventing the bond degradation from heat, friction, and environment.
- Heat protection to 230°C / 446°F — the leave-in forms a protective film around the hair shaft before blowdrying or heat styling, shielding the bonds and protein structure that bond-building treatments have repaired from being immediately re-damaged by thermal stress.
- Smooths, softens, and improves manageability without weight — rice proteins, amino acids, and Hyaluronic Acid collectively strengthen the hair fibre, improve moisture retention, and smooth the cuticle surface, leaving hair that is visibly shinier, softer, and significantly easier to manage.

What Else You Need to Know
The 93.5% bond repair claim from the Everlasting Bonds range is measured on the full system — shampoo + conditioner after 5 applications — not the leave-in alone. The leave-in's role is to extend and protect those results between washes. It can be used daily on towel-dried hair before styling, or applied to dry hair between washes as a softening and smoothing treatment. For seriously damaged hair, Milkshake recommends using the Everlasting Bonds Shampoo + Mask + Leave-In; for normal or mildly damaged hair, Shampoo + Conditioner + Leave-In is the daily routine.
Fragrance
Indulgent coconut, orchid, and warm vanilla. The signature Everlasting Bonds scent — warm, fresh, and long-lasting.
How to Use
Apply evenly to towel-dried hair, distributing from mid-lengths to ends. Comb through for even coverage. Do not rinse. Proceed with blowdrying or styling as usual. Can also be applied to dry hair between washes as a softening treatment.
FAQ
Is the 93.5% bond repair claim for the leave-in treatment alone?
No — the 93.5% bond repair figure is measured by ex-vivo instrumental test after 5 applications of the Everlasting Bonds shampoo and conditioner together. The leave-in's role is to seal and extend those results between washes, not to deliver the bond repair independently.
Can I use this leave-in on dry hair between washes?
Yes — Milkshake confirms it can be applied to dry hair as a softening and smoothing treatment between washes, not just to towel-dried hair before styling. Apply to lengths and ends and comb through — do not rinse.
Is this leave-in suitable for fine hair?
Yes — the formula is specifically described as lightweight and non-weighing. Reviews from fine-haired users confirm it adds softness and smoothness without limpness or product buildup, making it suitable for daily use on fine to medium hair.
