One of our core principles is this: if we understand the biology of hair, we can change it. As a biotech-powered haircare brand, we engineer innovative, biology-first haircare—and our molecular repair formulas are clinically proven to transform and renew hair from the inside out. 

K18 Co-Founder + CEO, Suveen Sahib, leads this charge with the ethos that we can do more with less when we formulate with synthetic biology and biotech.

The beauty industry isn’t known for being low waste. 

“The current industry conversation drives over-consumption and waste with a narrative that encourages the need for multi-step routines and excess usage,” Sahib says. “When you really think about it, one hair routine with up to 10 products is pretty heavy on resource consumption. Not to mention, if your hair is already damaged and weak, ample product use further stresses your hair making it needier and propelling the vicious cycle.” But Sahib believes we can create less of an impact on the planet while also creating products that best serve our community of stylists and at-home users. 

Says Sahib, “We believe by developing products that understand the biology of your hair and focus on delivering optimal hair health, we can mitigate the need for ‘more.’ Simply, healthy hair needs less.”

By creating biology-first haircare, we can formulate with efficacy, sustainability, and biocompatibility at the forefront.

Stylists are the north star at K18; their expertise, experience, and knowledge drive us to create products that make healthier hair for all hair types and textures—possible because the K18PEPTIDE™ works at the molecular level, where all hair is the same. 

how K18 molecular repair works differently

After working with top bioscientists who spent 10 years mapping and testing the entire protein expression of the keratin genome—unlocking deeper understandings of hair than ever before—the K18PEPTIDE™ was born.

Our K18PEPTIDE™ addresses damage on a deeper level, working at multiple points inside the hair fiber to reverse damage from bleach* + color*, chemical services*, and heat*. By working at the innermost layers and addressing breaks holistically across multiple points, K18 is able to deliver universal lasting + progressive strength + elasticity.
