Kristin Ess Peptide Bond Repair Hair Mask, 5 oz — lightweight leave-in with bond support and 450°F heat protection

This leave-in mask combines bond-supporting science with moisture-rich conditioning to address dry, chemically treated, or heat-stressed hair without weighing it down. Formulated with a Bondmimetic Molecular Complex and biomimetic peptides, it aims to improve manageability and resilience after color, lightening, or styling damage. The creamy, non-greasy formula can be applied to damp hair before styling or air-drying for smoother, stronger-looking results.

How does this treatment rebuild weakened hair fibers?

The formula uses Bondmimetic Molecular Complex and biomimetic peptides designed to interact with the hair structure and support strand integrity. While not a permanent repair, these ingredients work to reinforce and temporarily strengthen compromised areas so hair feels firmer and less prone to breakage during styling.

• Contains Bondmimetic Molecular Complex to help improve strand strength
• Biomimetic peptides mimic natural hair-building elements
• Clinically tested to increase hair strength in treated groups

Will this weigh my hair down or leave residue?

Kristin Ess formulated this mask to deliver hydration without heavy buildup—ideal for fine to medium textures that need moisture and repair. The lightweight, leave-in texture absorbs easily so you get softness and slip without limpness or visible residue.

• Lightweight conditioning for soft, manageable strands
• Non-greasy finish suitable for everyday styling
• Works on damp hair before air-dry or heat styling

Does it protect hair from heat styling and color damage?

This treatment provides heat protection up to 450°F, helping shield hair during blow-drying or hot-tool styling. It’s also formulated to support hair that’s been affected by color, bleach, or chemical processes by improving feel and perceived strength after repeated use.

• Heat protection rated to 450°F for hot-tool styling
• Helps restore softness and manageability after chemical services
• Supports smoother surface texture for easier styling

How do I use the leave-in mask for best results?

Apply a small amount to towel-dried hair, concentrating on mid-lengths and ends, then comb through for even distribution. Style as desired—air-dry for natural texture or use heat tools, keeping styling temperatures within recommended limits.

• Use on damp hair after shampoo and conditioning
• Start with a pea- to nickel-sized amount, adjust by hair length and porosity
• Comb through and style; reapply lightly on dry ends if needed

Who this product is for: This Kristin Ess+ Peptide Bond Repair Hair Mask suits anyone with dry, weakened, or chemically treated hair who wants stronger-feeling strands without heavy oils or buildup. It’s helpful for color-treated and heat-styled hair seeking improved manageability, hydration, and thermal protection in an easy-to-use leave-in treatment.
