System Professional Smoothen S3 Hair Mask - Hair Mask 400ml

Designed specifically for unruly and frizzy hair, the System Professional Smoothen S3 Hair Mask provides intensive structural care in a precise 400ml formulation.

This treatment moves beyond temporary smoothing by working directly on compromised areas to improve hair structure. The concentrated mask delivers intensive care that reinforces weakened strands, allowing natural textures to settle into a consistently smooth finish. By addressing internal weakness alongside surface frizz, it helps maintain manageable hair between washes.

• Tackles unruly and frizzy hair by smoothing cuticle disruption
• Improves hair structure through deep penetration and reinforcement
• Leaves hair smooth with lasting structural support rather than superficial coating
• Packed in a 400ml container to ensure consistent potency across multiple applications

Use this mask as part of a regular cleansing routine by applying to wet hair, allowing it to process, and rinsing thoroughly. The substantial capacity allows for repeated use without diluting the active conditioning balance. When managing stubborn texture or seeking reliable straight-line results, this System Professional formulation builds foundation-level strength and eliminates the unpredictability associated with high-frizz hair.
