K18 Leave-In Molecular Repair Hair Mask User Manual (Model K18-31007)

1. Introduction

The K18 Leave-In Molecular Repair Hair Mask is an at-home treatment designed to renew hair to its most youthful, healthy state. This patented formula works to repair even the most extreme damage caused by bleach, color, chemical services, and heat. It aims to create hair that looks and feels like new by addressing damage at a molecular level.

2. Key Features

At-home Leave-In Treatment: Infused with the patented K18Peptide to renew hair to its most youthful, healthy state.
Repairs Extreme Damage: Works to repair damage caused by bleach, color, chemical services, and heat.
Creates Hair Like New: Travels into the inner-most layers of hair to reach the core polypeptide chains, reconnecting broken chains responsible for hair strength and elasticity.
Renews All Hair Types: Transforms even the most extreme damage into hair that looks and feels like new, suitable for all hair types and generations.
Lasting Results: The K18Peptide mimics the natural building blocks of hair, integrating with keratin chains to rebuild and restore hair immediately and over time, with results that won't wash away.
Biotech-Powered: The world’s first patented biotech treatment that renews chemically damaged hair from the inside out in just 4 minutes, restoring strength, softness, smoothness, and bounce.

3. How It Works

The K18 Leave-In Molecular Repair Hair Mask utilizes the patented K18Peptide to penetrate the hair's innermost layers. This peptide is specifically designed to reconnect broken polypeptide chains, which are essential for hair's strength and elasticity. Unlike temporary solutions, K18 works to rebuild the hair's internal structure, providing lasting repair and transforming damaged hair into a healthier state.

The diagram highlights that the K18Peptide works on the polypeptide chains to reconnect broken bonds, renewing hair strength and elasticity.

4. Usage Instructions

For optimal results, follow these steps:

Shampoo Hair: Wash your hair with shampoo. Do not use conditioner.
Towel-Dry Thoroughly: Gently towel-dry your hair until it is damp, not dripping wet.
Apply Mask: Apply 1-3 pumps of the K18 Leave-In Molecular Repair Hair Mask from ends to roots. For the 15ml sized mask, 3-9 pumps may be used. Remember, less is more.
Wait 4 Minutes: Allow the product to sit for 4 minutes. Do not rinse it out.
Style as Usual: After 4 minutes, you can comb, add product, or style your hair as usual.

5. Important Notes for Maximizing Repair

Why Detox? Using a detox shampoo (like K18 detox shampoo) removes product buildup, oil, and metals from hair. Clearing buildup ensures maximum penetration of the K18Peptide.
Why Skip Conditioner? Conditioner can block the K18Peptide from penetrating effectively into the hair structure.
Why Wait 4 Minutes? Waiting 4 minutes before applying additional products allows the K18Peptide to provide maximum reparative benefits and reach the innermost layers of your hair.
How Often to Use: Use for 4-6 consecutive washes, then every other wash or as needed.
Activating the Product: You do not need to warm the product between your hands to activate it. You can work it between your hands to help with even distribution.
