How quickly will I see reduced frizz and more shine?

Most users notice frizz control and visible shine after the first application. The serum absorbs quickly without leaving residue, delivering smoother-looking hair immediately and improved manageability with continued use.

• Works instantly on damp or dry hair
• Reduces frizz for up to 72 hours when styled properly
• Provides 2x visible shine versus untreated hair
• Leaves hair soft, not greasy

Will this product protect my hair from heat styling and sun exposure?

The formula contains Pro-Vitamin B5 and specialty rice protein to help guard hair against hot tools and solar damage. It offers thermal protection up to 450°F and ingredients that support defense from pollution and environmental aggressors.

• Heat protection rated to 450°F
• Rice protein aids solar protection
• Edelweiss extract helps combat environmental stress
• Supports color- and chemical-treated hair during styling

How do I apply the serum for best results?

Dispense 1–2 pumps, rub between palms, then apply through the mid-lengths and ends. Use on damp hair before styling to lock in moisture and on dry hair to smooth frizz and add shine. Adjust amount for hair thickness and length to avoid weighing down fine hair.

• Use 1–2 pumps for short to medium hair, more for long or coarse hair
• Apply from mid-shaft to ends—avoid the roots for fine hair
• Layer under heat tools or use as finishing touch on dry hair
• Suitable for daily use or as-needed touch-ups
