Moroccanoil High Shine Gloss Mask Review

Hair masks are weekly leave-on treatments that go beyond conditioner — penetrating the hair shaft to deliver concentrated oils, proteins, or moisturizers. Moroccanoil's High Shine Gloss Mask ($48, 4.7 stars, 898 reviews) is the brand's signature weekly mask leveraging argan oil + glossing actives. We tested it for 6 weeks on color-treated combination hair.

TL;DR

The right weekly hair mask for color-treated, heat-damaged, or dull hair wanting argan oil + shine boost. 10-minute leave-on; rinses cleanly; visible shine improvement after 4-6 weekly uses. Premium tier ($48 vs $30 Olaplex No. 8). Skip if you have very fine hair (mask weighs down) or if you want bond repair (Olaplex No. 3 is the alternative).

Why It Matters

Weekly hair masks fill the gap between daily conditioner (light moisture) and bond-repair products (Olaplex No. 3). Masks deliver concentrated oils + proteins + moisturizers that sit on hair longer (10+ min vs conditioner's 2-3 min) and penetrate the cortex.

Moroccanoil's argan oil base is genuinely effective for shine — the oil molecule is small enough to penetrate the hair shaft rather than just coating the surface. After 4-6 weekly uses, color-treated hair shows visible shine improvement.

Who It's For

• Color-treated hair owners. Argan oil preserves color while adding shine.

• Heat-styling regular users. Mask compensates for heat damage.
• Multi-product routine builders. Pair with shampoo + conditioner + leave-in.
• Premium tier shoppers. Salon-quality at home.
• Skip if you have very fine hair (will weigh hair down), if you want bond repair (Olaplex No. 3 is the alternative), or if budget tops at $30 (Olaplex No. 8 is comparable).

How to Use

• After shampoo, squeeze excess water from hair
• Apply quarter-sized amount to mid-lengths and ends (avoid roots if hair is fine)
• Comb through for even distribution
• Leave on 10 minutes (longer for very damaged hair, up to 20 min)
• Rinse thoroughly with lukewarm water
• Style as usual
• Use weekly; alternate with Olaplex No. 3 if bond-repair needed

How It Compares

• vs Olaplex No. 8 Bond Intense Moisture Mask ($30): Olaplex adds bond-repair chemistry. Pick by goal — Moroccanoil for shine, Olaplex for bond repair.
• vs Briogeo Don't Despair, Repair Mask ($40): Comparable premium tier. Pick by ingredient preference.
• vs Kérastase Masquintense ($55): Kérastase is salon premium tier. Pick if budget allows.
• vs Aussie 3 Minute Miracle ($5): Drugstore alternative. Different category — surface coating.
• vs Olaplex No. 3 Hair Perfector ($30): Different category — leave-on bond repair vs rinse-off shine.

Bottom Line

Moroccanoil High Shine Gloss Mask is the right weekly hair mask for color-treated, heat-damaged, or dull hair wanting argan-oil shine. Premium tier, 10-minute leave-on, color-safe. Olaplex No. 8 is the comparable alternative; Briogeo Don't Despair, Repair is the close competitor; drugstore alternatives lack the argan oil penetration. For "the weekly mask that adds visible shine," this earns the slot at $48.
