There's a version of your hair that only turns up on the day of a salon appointment: smooth, glossy, suspiciously well behaved. This is the 500ml treatment that recreates it in your own bathroom.
TL;DR: A rich, deep-conditioning mask from the reformulated Matrix Mega Sleek range. Jojoba oil locks humidity out while oleic acid restores moisture inside the hair fibre, so poofy, wispy, static-prone lengths come out smooth, shiny and manageable. Vegan formula, colour-safe, and it smells like salted caramel and Sicilian pistachio.
Product Details and Benefits
- Jojoba oil locks humidity out. It seals the hair surface so damp, muggy air can't get in and start a fight.
- Oleic acid restores essential moisture. This fatty acid works from inside the fibre, smoothing the cuticle rather than just coating it.
- Balances fibre moisture in both directions. The formula is built for high and low humidity, so it holds up in a sticky February as well as a dry, static-charged winter.
- Targets the awkward textures. Poofy, fluffy, wispy or staticky hair is exactly what the Mega Sleek Smoothie Supreme Mask was formulated for.
- Suits every hair type. Fine to coarse, straight to coiled, and safe for colour-treated, highlighted and natural hair.
- Vegan formula with no animal-derived ingredients or by-products, and a 98% biodegradable formula*.
- Packaging made from recycled plastic, excluding the cap and label.
- Fragrance worth mentioning. Salted caramel and Sicilian pistachio — the kind of scent that makes a three-minute wait feel like a treat.
- 500ml treatment size, enough for months of weekly masking.
How to Use
- Cleanse with the Mega Sleek Smoothing Shampoo first.
- Apply the mask from mid-lengths to ends, where frizz actually lives. Roots don't need it.
- Leave on for 3 to 5 minutes.
- Rinse thoroughly, then finish with the Mega Sleek 96H Anti-Frizz Topcoat before styling.
Pro tip: Swap it in for your conditioner rather than stacking it on top. Matrix designed the Smoothie Supreme Mask and the Mega Sleek Conditioner to be used interchangeably one to two times a week, so mask day doesn't add a step to your routine — it just upgrades one.
Why You'll Love It
Frizz-prone hair doesn't need a personality transplant, just better weather protection. Add the Matrix Mega Sleek Smoothie Supreme Mask 500ml to your cart and make humidity someone else's problem.
