MATRIX Mega Sleek 96H Anti‑Frizz Topcoat Serum — humidity resistant, heat protection up to 450°F

Matrix Mega Sleek 96H Anti-Frizz Topcoat Serum is a leave-in, water-free serum that creates a hydrophobic barrier to control frizz for up to 96 hours while protecting hair from heat styling up to 450°F.

This lightweight, vegan formula targets poofy, wispy, or static-prone hair by sealing strands against moisture and smoothing cuticles for lasting shine. Heat-activated and highly concentrated, the serum works with blow dryers, straighteners, curling irons, and diffusers to lock in sleekness that can withstand everyday humidity and last through up to five shampoos. The scent profile pairs Sicilian pistachio and salted caramel with vanilla, lemon, toasted almond, and jasmine for a warm, gourmand finish.

How does this serum prevent frizz on humid days?

The serum forms a hydrophobic topcoat that repels moisture, reducing the swelling of the hair shaft that causes frizz. Because the formula is water-free and concentrated, a small amount creates an effective barrier that lasts through varying humidity conditions.

• Creates a moisture-repellent film over hair cuticles
• Works in up to 97% humidity to minimize puffiness
• Maintains control for up to 96 hours per application

Will this protect my hair from heat styling tools?

Yes — the Mega Sleek serum activates with heat and supports styling by shielding strands at temperatures up to 450°F. It smooths fibers before you apply direct heat, helping reduce breakage and preserve the finished style’s sleek look.

• Heat-activated barrier for styling with hot tools
• Suitable for blow drying, flat irons, curling irons, and diffusers
• Helps hair withstand high-temperature styling without compromising smoothness

How long does the smooth, shiny effect last on treated hair?

The serum is formulated to provide visible smoothness and long-lasting shine that endures multiple washes. Because it’s concentrated and adheres to the hair’s surface, the protective effect and gloss can remain noticeable for up to five shampoos under normal use.

• Delivers instant fiber smoothness and vibrant shine
• Effect persists through multiple washes — up to 5 shampoos
• Lightweight finish avoids greasy buildup while maintaining gloss

How should I apply the Topcoat Serum for best results?

Apply a small amount to damp or dry hair, distributing evenly through lengths and ends before heat styling. For concentrated frizz, focus on mid-lengths and ends; for overall control, work from roots to tips sparingly. Shake well, pump, then style as usual.

• Shake bottle, pump a small dose, and spread between palms
• Apply through mid-lengths and ends; avoid over-applying at roots
• Use hot tools to activate the hydrophobic seal for maximum hold

Who is this for: Matrix Mega Sleek 96H Anti-Frizz Topcoat Serum is designed for anyone battling frizz or humidity-related volume — from fine, flyaway hair to thicker, unruly textures — and for people who regularly use heat tools. It suits all hair types and is ideal for those who want a concentrated, vegan leave-in that delivers long-lasting control, heat protection, and a refined, gourmand scent without heavy residue.
