OLAPLEX 4-IN-1 Moisture Mask – Professional 370ml
Professional moisture treatment | Bond-building repair | Lightweight shine and softness
Overview
OLAPLEX 4-IN-1 Moisture Mask is an intensely concentrated, salon-only treatment that fuses deep hydration with patented bond building to revive hair after chemical services and severe dehydration. Designed for professional results in just 10 minutes, it leaves hair supple, glossy, and full of body.
What It Does
- Replenishes dry, dehydrated strands without weighing hair down.
- Repairs disulfide bonds to improve strength and moisture retention.
- Smooths the cuticle for slip, easy detangling, and mirror-like shine.
- Transforms rough, over-processed hair into soft, supple, healthy-looking lengths.
- Ideal as a post-bleach or post-color add-on service.
Key Ingredients
- Bis-Aminopropyl Diglycol Dimaleate – Patented OLAPLEX Bond Building Technology that repairs broken disulfide bonds for lasting strength.
- Squalane – Biomimetic lipid that restores internal moisture balance and prevents future moisture loss.
- Ceramides – Rebuild the cuticle lipid layer to lock in hydration and enhance smoothness.
Who Is It For?
- Post-bleach or post-color clients needing immediate moisture and repair.
- Chemically straightened or permed hair requiring structural reinforcement.
- Very dry, brittle, over-processed lengths and ends.
- 100% human hair extensions (avoid attachment points).
How to Use
A. Standalone In-Salon Application
- Shampoo; gently towel-dry the hair.
- Apply 1–3 pumps, comb through for even coverage.
- Process 10 minutes; rinse thoroughly and style as desired.
Pro Tips: Use immediately after chemical services; for extreme damage, process under gentle heat. For extra hydration, layer Nº.5 Leave-In after rinsing the mask.
B. Within the OLAPLEX System
For best results, start with the OLAPLEX Broad Spectrum Chelating Treatment to dissolve mineral/metal buildup, hard-water deposits, chlorine, and product residue. Chelation clears the pathway so OLAPLEX bond-building and moisture actives can penetrate more evenly, enhancing softness, slip, and shine. After chelating and rinsing, apply 4-IN-1 Moisture Mask as the targeted post-service hydration and repair step.
Integrate 4-IN-1 as the post-service moisture-and-repair step in the complete OLAPLEX regimen.
Results
- Hair feels softer, smoother, and easier to detangle after one use.
- Improved moisture retention thanks to repaired bonds.
- Lightweight body and shine without residue.
