Protein plays a critical role in maintaining curl strength, elasticity, and moisture retention particularly in the Middle East, where UV exposure, hard water, and humidity accelerate protein loss. Hair is primarily made of keratin, meaning protein should be part of ongoing curl maintenance, not an occasional treatment. The key is balance: selecting the right type and frequency of protein based on porosity, lifestyle, and climate to reinforce the hair fibre without causing stiffness.

Mousse and foams are often dismissed as too lightweight to deliver lasting curl definition, especially in high-humidity climates like Dubai, UAE, Riyadh and Doha. In reality, performance depends on formulation, layering and application. The Doux Mousse Def challenges outdated assumptions with a dual hold system, humidity resistance and intentional hydration. Designed to perform through heat and seasonal shifts, this foam delivers definition, longevity and touchable curls, without stiffness or buildup.
