Part of The Doux's Black Party collection, Act Right Anti-Humectant Serum (2 oz / 59 ml) is formulated to act as an invisible barrier against moisture in the air. Designed to protect straight and heat-styled hair from swelling or reverting, this ultra-lightweight, non-greasy serum seals hair cuticles, smooths flyaways, and delivers a glossy, high-shine finish without weighing strands down.

Why You’ll Love It:

• Humidity & Frizz Shield: Blocks environmental moisture to prevent silk presses, blowouts, and defined curls from reverting or puffing up.

• Weightless & Non-Greasy: Adds silkiness and high-voltage shine without leaving a heavy, oily build-up.

• Cuticle Sealant & Thermal Protection: Smooths split ends, locks down cuticles, and shields hair against heat damage.

• Versatile Finishing Touch: Perfect for pressing, flat ironing, or adding a sleek finish to silk presses, twist-outs, and sleek ponytails.

How to Use:

1. For Thermal Styling: Apply 2 to 3 drops to clean, dry hair before flat ironing or hot-tool styling to seal and protect.

2. For Finishing: Rub a small amount between palms and smooth over finished styles to lock out humidity, tame flyaways, and boost shine.

3. Re-application: Use sparingly on mid-lengths and ends throughout the week as needed.
