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.

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.
