EVA·NYC Bye Bye Brass Toning Hair Mask for Blonde, Gray & Lightened Hair — Ultra-Violet Pigment, Wild Cherry Bark, 8.4 fl oz

An ultra-violet purple toning mask that neutralizes yellow/brassy tones while deeply moisturizing blonde, gray, and lightened hair. EVA·NYC's Bye Bye Brass Toning Hair Mask is a creamy treatment formulated to refresh cool tones and restore softness between salon visits. Powered by ultra-violet pigments to counteract unwanted warmth and Wild Cherry Bark to replenish moisture, this mask targets brassiness without over-drying. Its Ginger Rose fragrance—ginger, freesia, turmeric, and soft musk—adds a salon-worthy scent while the formula omits many controversial additives for a cleaner, mindful approach to haircare.

How quickly will I see less brass after using this mask?

Most users notice reduced yellowing and a cooler appearance immediately after rinsing. The ultra-violet pigments deposit tone-correcting color while the creamy base smooths the hair cuticle for improved shine.

• Leave on 3–5 minutes for standard toning results.
• Stronger toning achieved with slightly longer processing, as needed.
• Visible coolness and brightness after a single treatment.

Will this product dry my hair or add moisture?

This mask balances toning with hydration: Wild Cherry Bark and the conditioning base restore softness and manageability as pigments neutralize brass. It’s designed to leave hair feeling smooth rather than brittle.

• Rich, creamy texture that conditions mid-lengths and ends.
• Improves softness and reduces frizz with regular use.
• Helps hair appear shinier and healthier while toning.

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

Apply to clean, wet hair, focusing on mid-lengths to ends where brass and dryness concentrate. Rinse thoroughly after letting it process for 3–5 minutes; use weekly or when brass starts to show.

• Shampoo first, then towel-blot excess water.
• Massage mask evenly through mid-lengths and ends.
• Rinse well after recommended time; repeat weekly or as needed.

Is this safe for gray or color-treated hair?

The formula is crafted for blonde, gray, and lightened hair to maintain cooler tones and boost manageability. It’s intended to refresh color appearance and add moisture without stripping existing color when used as directed.

• Formulated to neutralize brass on color-treated hair.
• Suitable for natural grays that need brightening and toning.
• Use in moderation to avoid over-depositing pigment on very porous hair.

Who is this for This mask is ideal for people with highlighted, bleached, blonde, or silver hair who want to reduce yellowing between salon appointments while improving softness and shine. It’s also a good choice for anyone seeking a fragrant, conditioning toning treatment made with responsibly sourced ingredients and a cleaner formulation. Use it weekly or as your hair’s brassiness dictates to maintain a cool, luminous finish without compromising moisture.
