The Olaplex 4-in-1 Moisture Mask is a professional-strength, highly concentrated reparative treatment designed to provide intense hydration, shine, and body to dry or damaged hair. It is primarily intended for in-salon use but is often sought by clients with severe dryness who need a more potent solution than the at-home.Intense Hydration: Clinically proven to increase moisture by 74%.

Enhanced Shine and Smoothness: Delivers 84% more shine and smoothness to the hair.

Added Body: Provides 94% more volume/body, ensuring hair does not feel weighed down.

Cuticle Sealing: Features a slightly acidic pH of 4.5, which helps close the hair cuticle to improve porosity, retain color, and eliminate static. Patented Bond Building Technology: Uses Bis-Aminopropyl Diglycol Dimaleate to repair disulfide bonds at a molecular level, restoring hair strength.

11 Vital Amino Acids: These serve as the building blocks for protein to repair hair without the risk of protein-sensitive brittleness.

Professional-Strength Ceramides and Oils: A high concentration of nourishing agents that mimic the hair’s natural lipids to restore the moisture barrier.

Protein-Free Formula: Unlike some reparative masks, it contains no proteins, making it safe for low-porosity or protein-sensitive hair.

How to Use: After shampooing, apply 1–3 pumps to clean, damp hair, focusing on mid-lengths to ends.
Duration: Leave on for 10 minutes before rinsing thoroughly.
Hair Types: Suitable for all hair types, including color-treated, chemically-treated, and super curly hair.
