NYX PROFESSIONAL MAKEUP Thickening Brow Mascara, Brunette — Vegan Fiber-Infused, 16H Hold

NYX Professional Makeup Thick It Stick It Thickening Brow Mascara in Brunette is a vegan, fiber-infused eyebrow gel that tints, builds and holds brows for up to 16 hours.

Designed as a no-fuss tinted brow mascara, this lightweight gel blends plant-origin fibers with a precise wand to thicken and define hairs while resisting flaking, smudging and transfer. The formula layers easily so you can go from subtly filled to visibly fuller brows in moments, and the Brunette shade is created to flatter medium-to-deep brown hairs with a natural finish. PETA-certified cruelty-free and crafted for everyday wear, it works with NYX's suite of brow tools if you want extra shaping or long-term styling.

How does this brow mascara thicken eyebrow hair without looking stiff?

The product uses ultra-buildable tinted fibers suspended in a gel base that adhere to each hair, visibly increasing volume while maintaining flexible movement. Because the fibers mimic hair-like texture, results read as natural rather than cakey. The brush deposits product precisely so you can control the amount and avoid clumps.

• Plant-origin fibers add dimension with each coat
• Gel binder keeps hairs soft and touchable
• Precision wand provides targeted application for sparse areas

Will the Brunette shade suit my brow color and skin tone?

Brunette is formulated for medium to deep brown brows and aims to harmonize with warm and neutral undertones. It gives a subtle tint rather than a stark dye, so it blends into existing hair color to enhance shape and depth. If you have very dark or very light brows, consider testing or comparing adjacent shades within the 8-shade range.

• Medium-deep brown tint for natural depth
• Sheer, buildable coverage avoids overpowering lighter hair
• Layerable formula lets you customize intensity

How long does the hold last and how does it resist smudging?

The formula is designed for up to 16 hours of wear with resistance to flaking, smearing and transfer, so brows should stay styled through a full day. A combination of film-forming agents and the fiber-gel system locks fibers in place without creating a crunchy finish. For active days or humid conditions, allow a few seconds of dry time after application for best longevity.

• Up to 16 hours of wear with everyday activity resistance
• Flake- and transfer-resistant gel matrix
• Quick-dry formula reduces smudging after application

How do I apply it for the most natural-looking results?

Start with clean, dry brows and use short upward strokes to coat hairs, concentrating on sparse areas. Build in thin layers—one coat for subtle tint, two to three for added thickness—and finish by brushing through to shape. Combine with a pencil or powder base if you want sharper arches or precise edges before sealing with the gel.

• Apply from root to tip using the wand’s tip for accuracy
• Layer gradually to avoid over-depositing product
• Use after pencils/powders for definition, or alone for quick fill

Who is this for: This brow gel is ideal for anyone seeking an easy, cruelty-free way to add volume, tint and hold to natural brows—particularly users with medium to dark brown hair who want a hair-like finish. It's suited to busy morning routines, makeup beginners who prefer a single-step brow product, and makeup enthusiasts who like to combine tools for a more polished look. Choose Brunette if you want a warm-to-neutral brown that enhances depth without looking painted on.
