The CORTEX BEAUTY Keratin 3-Piece Hair Care Set includes a hydrating shampoo, strengthening conditioner, and leave-in conditioner designed to repair and nourish all hair types. Each product is formulated with keratin to enhance moisture retention, improve hair strength, and reduce tangles. The shampoo gently cleanses while fortifying strands, the conditioner deeply conditions for smoother texture, and the leave-in provides daily hydration and protection. Together, they support healthier, softer, and more manageable hair with consistent use.
