XMONDO Slate Grey Depositing Mask — Semi‑Permanent Hair Dye 8 fl oz with Bond Booster & Hyaluronic Acid

XMONDO Color Slate Grey Depositing Mask is a semi-permanent, nourishing hair mask that deposits cool slate-grey pigment while strengthening and hydrating hair.

If you want a muted, steely grey finish without bleach-and-developer commitment, this depositing mask layers pigment and care in one step. Infused with Bond Booster Technology, hyaluronic acid, and plant-based protein, it tones and treats hair as it deposits color. The vegan, cruelty-free formula is formulated to work especially well on blonde to light-brown bases and fades gradually over two to four weeks, offering a reversible way to experiment with smoky grey tones.

How does the Slate Grey mask create color while repairing hair?

The mask combines concentrated pigments with bond-supporting and moisturizing ingredients so color and conditioning happen together. Bond Booster Technology helps reinforce weakened links in the hair shaft while hyaluronic acid attracts moisture to improve smoothness and manageability.

• Deposits cool-toned grey pigment evenly for a muted, steely result.
• Bond Booster works to strengthen internal hair structure during processing.
• Hyaluronic acid and plant proteins add hydration and surface slip for easier comb-through.

Will this work on my natural or color-treated hair?

Best results appear on blonde to light brown hair where the slate tone shows most vividly; darker hair will receive a subtler tint. The formula is safe for previously colored, curly, textured, and damaged hair, but it is not designed to fully cover gray roots or create dramatic lifts from very dark bases.

• Blonde/light brown: bold, true-to-tone payoff.
• Medium to dark hair: soft, smoky sheen rather than full opacity.
• Color-treated and textured hair: compatible and conditioning, results vary.

How do I apply it at home for even, long-lasting results?

Apply to clean, dry hair in sections while wearing gloves; comb through to saturate strands and process for about 20 minutes. Rinse with cool water using a stainless steel or dark-colored sink to prevent staining; color will slowly fade with regular washing over 2–4 weeks.

• Work on dry, freshly-washed hair for best pigment pickup.
• Section hair and apply evenly, using a comb to distribute the mask.
• Process roughly 20 minutes, then rinse with cool water to lock tone.

Is the product safe and what ingredients should I know about?

XMONDO Slate Grey Depositing Mask is vegan, Leaping Bunny cruelty-free, and free from ammonia, peroxide, parabens, and gluten. It uses pigment-rich dyes without a separate developer and includes moisturizers and plant proteins rather than harsh chemical conditioners.

• Vegan and cruelty-free, formulated without ammonia or peroxide.
• Includes Bond Booster Technology, hyaluronic acid, and plant-based proteins.
• No developer required—gentler on hair than permanent color systems.

Who is this for: this mask is ideal for people who want to experiment with a cool slate-grey look while improving softness and manageability, especially those with blonde to light-brown bases or previously lightened hair. It also suits anyone seeking a vegan, salon-grade semi-permanent alternative that conditions as it colors. If you need full gray coverage or dramatic color lifts from very dark hair, consider professional lightening before using a depositing mask.
