Our Game-changing Scientific Discovery

The way you treat your curls will never be the same. After a decade of scientific research, specifically proteomic research, Nexxus scientists uncovered something breakthrough – curly and straight hair don’t just have a different structure, but the proteins that make up those structures are different. Certain proteins appear two to six times greater in frequency in curly hair than in straight. These curly hair proteins are much richer in specific protein building blocks – Glycine & Serine amino acids.

With this in mind and knowing curly hair is innately prone to breakage, we set out to craft a first of its kind ProteinFusion Blend, made up of the strengthening building blocks that curly hair needs.
