EVA·NYC Bye Bye Brass Purple Toning Hair Mask — 8.4 fl oz | Anti-Brass + Deep Moisture for Blonde & Gray

EVA·NYC Bye Bye Brass Purple Toning Hair Mask is a rich purple treatment that neutralizes unwanted brassy and yellow tones while deeply moisturizing blonde, gray, and lightened hair.

This salon-style mask combines ultra-violet pigments with moisturizing wild cherry bark to tone and hydrate hair between coloring appointments. The creamy formula deposits violet pigments to counteract warm undertones, while conditioning agents restore softness and shine. A Ginger Rose fragrance — layered with freesia, warm turmeric, and soft musk — turns each application into a sensorial moment. The product is formulated without over 1,300 controversial ingredients and uses responsibly sourced components, making it a mindful choice for color-maintained hair.

How does this mask neutralize brass and yellow tones?

The mask contains ultra-violet pigments that deposit cool violet color onto the hair shaft, which visually cancels out yellow and orange brassy tones through color theory. Pigment intensity is balanced with conditioning agents so the mask tones without over-depositing, delivering cooler, fresher-looking blonde, gray, and lightened hair after each use.

• Ultra-violet pigments specifically target warm undertones.
• Violet pigment plus cream base ensures even distribution.
• Works gradually — use weekly or as needed to maintain tone.

Will this mask moisturize and improve hair texture?

Yes — wild cherry bark and other conditioning ingredients help replenish moisture and smooth the cuticle. The mask’s rich, creamy texture detangles and softens dry, porous strands, making hair feel silkier and easier to style while preventing the brittle look often seen after lightening.

• Wild cherry bark provides targeted hydration to mid-lengths and ends.
• Creamy formula smooths the hair cuticle for enhanced shine.
• Leaves hair feeling softer and more manageable after rinsing.

How do I use the Bye Bye Brass mask for best results?

Use the mask on clean, shampooed hair. Apply from mid-lengths to ends, leave on for 3–5 minutes, then rinse thoroughly; frequency depends on your level of brassiness — typically once a week or as needed. For stronger toning, leave toward the longer end of the time range but monitor results to avoid over-toning.

• Shampoo first to remove buildup for even pigment deposit.
• Apply evenly from mid-lengths to ends; avoid scalp for best toner control.
• Leave 3–5 minutes; increase cautiously if deeper toning is required.

Is this product suitable for all lightened shades and gray hair?

The formula is designed for a wide range of blonde, highlighted, and naturally gray hair types seeking cooler tones. It tones brassiness without bleaching or altering base color dramatically, but results vary by porosity and previous processing. For very porous or heavily damaged hair, shorter processing times and less frequent use are advisable.

• Works on natural gray, single-process blonde, highlights, and balayage.
• Adjust leave-in time based on hair porosity and color intensity.
• Safe for regular use to maintain vibrancy between salon visits.

Who this is for: EVA·NYC Bye Bye Brass Purple Toning Hair Mask is aimed at anyone with lightened, highlighted, or gray hair who wants to reduce warm, brassy tones while adding moisture and shine. It’s ideal for people who color-manage at home or want to extend salon results: those seeking a balanced toner that conditions as it corrects, and users who prefer thoughtfully formulated products without a long list of controversial ingredients.
