Welcome to fusion protein 101, where we’ll explain this exciting biotechnology and how we use it to deliver the future of haircare. In short, fusion proteins are combinations of different proteins that create new molecules with new functionality that can provide benefits not achievable by the individual proteins.

But let’s back up for a second: have you ever been to a fusion restaurant? 

“Fusion” cuisine is created by combining the culinary traditions of different regions or cultures. Combining these distinct flavor profiles creates novel, unique dining experiences.

What if we told you that you can create the same novel experience with biology by combining elements from different proteins to create new, high-performance ingredients?

Just like different types of food are combined to create new flavor profiles at a fusion restaurant, fusion proteins are combinations of two or more different proteins to create new hybrid proteins with specific, novel functionalities. 

Scientists create these fusion proteins using synthetic biology to combine different genes, sequences of DNA that contain the information needed to code for specific biological traits. The fusion genes are inserted into microorganisms like bacteria or yeast, where they produce the fusion protein. 

Fusion proteins are commonly used in the pharmaceutical industry and are now being used in beauty too. These hybrid proteins provide exciting new drug treatments or novel cosmetic benefits that can solve previously unaddressed problems with biology.

Scientists are producing fusion proteins to create new medicines. Mixing and matching the functionalities of different proteins allows drug developers to better target drugs to specific sites or cells in the body or to extend the duration of their therapeutic effects.

For example, antibodies (the proteins your body uses to fight off infection) have been combined with other proteins to create fusion proteins that better target treatments to the source of disease or damage.

Fusion proteins are also emerging as ingredients that offer new ways to address your beauty needs in a way that’s optimized for your biology. Fusion proteins are being used in beauty to create new ingredients with novel functionalities.

Our new AirWash™ dry shampoo uses fusion protein technology to remove unwanted hair odor. But how? We created a fusion protein that combines keratin-binding segments with the functionality of an odorant-binding protein inspired by nature to enable better interaction with hair. Together, these proteins deliver long-lasting odor protection optimized for your hair’s biology.
