How quickly will I see frizz reduction?

You can expect immediate improvement: the formula works in one minute while you’re in the shower and is clinically shown to reduce frizz by about 73% after a single use. The mask also deposits humidity-deflecting ingredients that release over time to maintain control for several days.

• Acts in 60 seconds during your rinse-out step
• Clinically proven ~73% instant frizz reduction after one use
• Time-released protection keeps frizz down for up to 72 hours

What key ingredients smooth and protect hair?

The treatment pairs glycolic acid with botanical extracts to smooth the hair cuticle and create a barrier that resists moisture intrusion. Glycolic acid helps refine and flatten the hair surface while water lily and sea buckthorn add conditioning, antioxidants and shine.

• Glycolic acid: smooths cuticle, aids manageability
• Water lily extract: lightweight conditioning and softness
• Sea buckthorn superfruit: nourishment, shine, and antioxidant support

How do I use this mask for best results?

Apply to clean, towel-dried hair in the shower, leave on for 60 seconds, then rinse thoroughly. Use as a weekly deep-touchup or any time you need quick anti-frizz performance before styling.

• After shampoo, distribute evenly through mid-lengths and ends
• Leave on 60 seconds, then rinse out completely
• Style as usual; repeat weekly or as needed for humidity-prone days

Will it weigh my hair down or affect styling?

The formula is designed to smooth without heavy buildup, improving manageability and shine rather than leaving residue. It rinses clean and supports styling by creating a smoother surface for heat tools or air-drying.

• Rinse-out treatment that won’t leave heavy residue
• Improves comb-through and styling slip
• Enhances shine and softness without greasiness
