How to kill brass without killing your blonde
Warm, brassy tones are the price blonde, ash, and grey hair quietly pays over time. Ash Splash is the fix, a two-product system that cools your tone, kills the brass, and keeps your hair conditioned while it's at it. Use the Treatment Mask for a deep reset, the Spray to top up between washes, or both together to keep your colour salon-fresh all the time.
Here's how each one works and how to get the most out of it.
Ash Splash Treatment: The Mask That Kills Brass and Cools Your Blonde
The Benefits
Cooler, fresher blonde, ash, and grey tones with the brassiness stripped right out. Deep conditioning that leaves hair smooth, soft, and lustrous. Built-in detangling, so it does the work of two products in one. A glossy, healthy-looking finish that catches the light. An easy, mess-light routine you can do at home in half an hour.
How It Works
The toning happens through colour-correcting pigments that counteract unwanted warmth, cool tones cancel out brassy yellows and oranges, which is what brings your blonde or grey back to a clean, true shade. While the pigments tone, a rich conditioning base goes to work:
Hydrolyzed Keratin strengthens and smooths the hair, reinforcing strands left fragile by lightening.
Hyaluronic Acid & Panthenol draw in and hold moisture, leaving hair plump, soft, and hydrated.
Wheat Germ Oil, Jojoba Seed Oil & Tocopherol (Vitamin E) nourish and add shine, replacing the richness that processed blonde so often loses.
Linoleic & Linolenic Acids condition and support the hair's natural barrier for a smoother, healthier feel.
What You'll Need
Get everything within reach before you start.
Ash Splash Treatment Mask
A wide-toothed comb
A shower cap
Gloves (toning pigments can stain)
A towel you don't mind staining
How to Use
1. Apply. Work the mask through your hair from roots to ends, section by section, so every strand is covered.
2. Comb through. Use a wide-toothed comb to spread the product evenly, this is what gives you a consistent tone with no patchy spots.
3. Cover and wait. Pop on a shower cap and leave the mask on for at least 30 minutes.
4. Rinse cool. Rinse with cold water to seal the cuticle and lock in maximum shine.
Good to Know
The longer you leave it (within reason), the stronger the toning. If your hair is very brassy, lean toward the full time, and remember a strand test is always smart the first time, so you know exactly how your hair takes the tone.
Ash Splash Spray: Cool-Toned Blonde, Topped Up Between Washes
How It Works
Like the mask, the spray uses colour-correcting pigments (CI 50415 and CI 77266) to neutralise unwanted warmth, the cool tones cancel out brassy yellows and oranges to keep your blonde looking clean. Alongside the toning, conditioning agents smooth and detangle while Panthenol draws in moisture, so each spritz leaves hair softer and more manageable, not stiff or dry.
How to Use
1. Start clean and damp. Use on freshly washed, towel-dried hair.
2. Target the warmth. Spray directly onto the areas showing yellow or orange tones.
3. Comb through. Comb thoroughly to spread the product evenly for a consistent, brass-free finish.
Good to Know
Focus your spritzes where brass shows up most, usually around the front, hairline, and ends. Build it up gradually rather than soaking the hair all at once, you can always add more, and even distribution is what keeps the tone looking natural.
Mask or Spray? Use Both.
They're built to work together. The Treatment Mask is your deep reset, use it when brass has built up and your blonde needs a proper cool-down. The Spray is your maintenance, a quick top-up between washes that keeps the tone fresh so you're not chasing brass every week. Mask to reset, spray to maintain, and your blonde stays cool, bright, and brass-free for good.
The Results Speak for Themselves
The Payoff
Warm, tired blonde doesn't stand a chance. Whether you're resetting with the mask or topping up with the spray, Ash Splash keeps your tone cool, clean, and glossy, the kind of fresh-from-the-salon blonde that makes people ask where you get your hair done. No brass, no dullness, just colour you're proud to show off.
