FAQ

What is the Glycolic Gloss Shine Boosting Hair Mask?

L'Oréal Paris Hair Expertise Glycolic Gloss Shine Boosting Mask is an intensive shine-restoring treatment designed for dull hair lacking luster. Infused with Glycolic Acid, this luxurious mask penetrates and smooths the hair fiber to provide an instant, transformative gloss effect with smooth, silky results in just one use.

How does this product benefit dull hair specifically?

Dull hair has an uneven cuticle layer that scatters light instead of reflecting it. Our Glycolic Gloss mask targets this rough texture by perfectly smoothing down the hair cuticles. This alignment creates a highly reflective surface, visibly enhancing the hair with intense, mirror-like shine and outstanding softness without weighing it down.

Why is Glycolic Acid used in this formula?

Glycolic Acid is widely celebrated in skin care for its exfoliating and resurfacing power. When applied to hair care, our 12% Gloss Complex with Glycolic Acid deeply conditions and smooths the hair fiber from the inside out, taming rough textures to maximize light reflection for a radiant, long-lasting, and glossy finish.

What is the fragrance profile?

This product features an addictive, clean premium floral fragrance.

Is this product safe for daily use?

Absolutely. All L'Oréal Paris products undergo rigorous safety and efficacy testing. This lightweight, shine-boosting mask is safe for regular use as part of your weekly beauty routine to keep your hair smooth, healthy-looking, and intensely glossy.

How sfhould I apply the Glycolic Gloss Shine Boosting Hair Mask?

This quick, high-performance treatment fits easily into your regular washing routine:
• After shampooing with Glycolic Gloss Shampoo, apply a generous amount to wet hair.
• Work evenly through your lengths and ends, ensuring every strand is coated.
• Leave on for 3 minutes to allow the Glycolic Acid formula to deeply penetrate, then rinse thoroughly.
• For maximum shine, use in combination with the complete Glycolic Gloss routine.

How much product should I use?

A walnut-sized scoop is ideal for most hair lengths. Warm the creamy formula between your palms and distribute evenly from the mid-lengths down to the tips, avoiding the roots to maintain natural volume and lightness.

How does L'Oréal Paris prove the efficacy of these claims?

At L'Oréal Paris, our promises are strictly rooted in science. Every claim—from the instant +41% shine boost to the 10x smoother hair texture—is validated by rigorous instrumental and sensory testing protocols on dull hair. We invest significantly in Research & Innovation to ensure that our formulas are both safe and highly performant for our consumers.
