K18 Hair offers a single, hero product: the K18 Leave-in Molecular Repair Hair Mask. This mask is designed to deliver professional-grade hair repair in just 4 minutes. Here's a breakdown of their key offering:

Patented Peptide Technology: The K18 Leave-in Molecular Repair Hair Mask leverages a patented K18Peptide technology. This peptide is designed to penetrate the hair's inner cortex and repair broken disulfide bonds. These bonds are crucial for hair strength and elasticity, and can be weakened by chemical treatments, heat styling, or environmental damage.

Damage Repair: The K18 mask focuses on repairing existing hair damage, rather than simply masking it. This can lead to stronger, more resilient hair that is less prone to breakage and split ends.

Simple Application: Unlike some hair repair treatments, the K18 mask is easy to use at home. It's a leave-in product applied to clean, damp hair, requiring no rinsing.

Benefits: Users report benefits like increased hair strength, improved manageability, restored shine and softness, and reduced frizz.

Target Audience: K18 is suitable for all hair types and textures, and is particularly beneficial for those with damaged hair.

Cost: The K18 Leave-in Molecular Repair Hair Mask is a single, higher-priced product compared to some hair care lines. However, it offers a concentrated treatment and can potentially replace the need for other conditioners or masks in your routine.

Overall, K18 Hair focuses on a single, innovative product designed to deliver professional-grade hair repair in just 4 minutes. Their patented K18Peptide technology targets the hair's core structure to repair damage and restore strength, manageability, and shine.
