Protein Leave-in Treatment
Protein Leave-in Treatment
Hair is made up of around 90% protein. Over time, that structure weakens, leading to breakage, frizz and loss of shape. This lightweight leave in treatment feeds your hair with the proteins it needs to stay strong, elastic and healthy. Waves feel more resilient, smoother and easier to manage, with less breakage and fewer split ends over time. 150ml
