All the information you need to know is here:

What Is K18 Leave-In Molecular Repair Hair Mask?

In essence, K18 isn’t just another conditioning treatment. The brand advertises it as a highly effective solution that is scientifically advanced. The K18  Leave-In Molecular Repair Hair Mask is advertised as an innovative, scientifically proven remedy for hair restoration. Its primary component is the K18. Peptide TM is a proprietary substance that can penetrate the hair’s core and restore the integrity of keratin chains, the proteins responsible for hair elasticity and strength. It works to permanently repair the structure and elasticity of the hair. 

While traditional hair masks only offer temporary relief, K18 penetrates the hair shaft and repairs damage from within. Even if you suffer from long-term damage, regular use can result in positive effects on your hair over time.

It is a mask designed to repair harm caused by:

  • Bleaching and coloring. 
  • Flat irons and curling wands are examples of heat styling equipment. 
  • The use of chemicals such as relaxers or perms is another form of treatment. 
  • Mechanical stress (brushing, tight hairstyles) 

The unique feature is that it functions as a leave-in treatment, making hair restoration compensated in the regular process.

How to Use K18?

Although the process is slightly different from using traditional masks or conditioners, K18 is a refreshingly easy to use product. Here’s the step-by-step breakdown:

Application Instructions:

Shampoo: Use a strong shampoo to remove buildup before using the shampoo. It’s crucial to refrain from using any moisturiser during this initial step, as it can hinder the mask’ effectiveness. The Indian market, where hair oils and other heavy products are prevalent, requires a clarifying shampoo for optimal penetration. 

Towel-Dry: Follow up with a towel-dry after shampooing to keep your hair damp, not wet. Absorption of the product is ensured by this step. 

Apply K18: Apply K18 to damp hair by dabbing a small amount of the mask (1-2 pumps depending on hair length) and evenly spread it over the damaged areas or at the ends. Because it is a leave-in, you don’t even need to rinse. 

Wait: Let the product sit for 4 minutes to activate and repair the hair at the molecular level before application. 

Style as Usual: Following a four-minute interval, you can continue with your typical hairstyle. (No need to wash it off)

What is the ideal interval for usage?

If your hair is severely damaged, K18 suggests using the mask 1-2 times per week and gradually decreasing when your existing hairstyle improves. 

A minimum of 2 times weekly can help manage moderately damaged hair. Please refer to the details.

The Science Behind K18

The scientific basis of K18 sets it apart from other treatments. The molecular-based hair repair therapy PeptideTM. 

Keratin Damage Repair: Keratin is the primary component of hair, and it is believed to be a protein that provides its strands with resilience and support. Heat, chemicals, and mechanical damage can break the keratin bonds.’ K18’s peptide asserts that it will repair these bonds, leading to the enhancement and resilience of hair. 

Long-Term Results: PeptideTM can permanently alter the internal composition of hair by entering the hair cortex. Unlike regular remedies, this is not the case when it comes to being washed up after one use. 

Its scientific basis is established through clinical trials, and early consumers have observed significant improvements in hair texture, softness properties or strength over time. 

What makes K18 stand out as a game-changer in India?

In India, the hair care industry is highly diverse and intricate, with a broad range of hair types and issues. The stressors of hair stress can manifest in various ways, such as heat styling (a common occurrence for many) or harsh chemical use during hair colouring. Additionally, humidity and pollution are environmental factors that can result in untidy hair. K18 tackles these issues on a molecular level, providing an alternative to the commonly available masks and oils.

Why should one consider buying K18 in India?

Humidity & Pollution Protection: K18 is essential for providing hydration and repair in humid or polluted areas, helping to protect against pollution. It restores the naturally elastic fibres that are lost when exposed to harsh environmental conditions. 

Effectiveness for All Hair Types: The K18 mask is suitable for all hair types, including curly, wavy, straight, and fine hair. It has proven to work effectively. In the humid and tropical climate of India, it is crucial to repair any damage without causing hair loss or oiliness. This is particularly important. 


Keeps the hair from slipping on: Regular use can prevent further damage caused by daily styling routines, which is a major concern for many people in the Indian market who wear heat styling every day.
