Living Proof Triple Bond Complex Leave-In Treatment & Mask, 1.7 oz — Rebuilds Bonds, Heat Protection to 450°F

This concentrated 1.7 oz leave-in treatment doubles as an intensive hair mask to repair weakened strands and reduce visible signs of damage. Formulated to rebuild hydrogen, ionic, and covalent links inside the hair fiber, it supports stronger, smoother hair after just one use while offering thermal protection for heated styling. Use it as a quick leave-in to detangle and shield, or as a weekly deep-treatment mask for added restoration.

How quickly will I see improvement in hair strength?

Many users notice increased resilience after a single application, with ongoing benefits when used weekly. The formula targets multiple bond types to reinforce the hair structure, making strands less prone to breakage during styling and brushing.

• Works as a leave-in or rinse-out mask for flexible routines
• Designed to build hydrogen, ionic, and covalent bonds
• Reduces split-end appearance and improves manageability

Can this product protect hair from heat styling?

Yes — the treatment includes thermal protection suitable for most heated tools. Applied before styling, it helps shield hair when using blow dryers, straighteners, or curling irons at typical styling temperatures.

• Heat protection rated up to 450°F / 232°C
• Leaves hair smoother for easier styling and less friction
• Suits routine heat styling without compromising repair benefits

How should I use it for best results: leave-in or mask?

Both methods work; choose based on your time and hair needs. Use a small amount as a leave-in on damp hair for daily manageability and protection, or apply a generous layer as a weekly mask and rinse for deeper rebuilding.

• As a leave-in: apply sparingly to damp hair, style as usual
• As a mask: distribute through damp hair, leave 5–10 minutes, then rinse
• Weekly mask use delivers more noticeable repair over time

Will this treatment work on all hair types and damage levels?

The formula is developed to benefit a wide range of textures and damage patterns, from chemical or heat-stressed hair to mechanical wear. Results depend on the extent of damage and consistent use, but the multi-bond approach addresses structural weakness across hair types.

• Effective on color-treated, chemically processed, and heat-styled hair
• Helps reduce breakage and improve smoothness for many textures
• Works alongside regular care — complement with your favorite cleanser and conditioner

Who is this for? This treatment-mask suits anyone wanting to repair visible damage and increase hair strength while maintaining softness and shine. Ideal for people who frequently use heat tools, color their hair, or seek a once-weekly intensive treatment that also functions as a convenient leave-in for everyday protection and styling.
