What is Double Process Hair Color?

Discover double process hair color transformations from our luxury salons

Few services are as transformative as double process hair color. Double process is one of the most requested services for clients seeking luminous blondes, fashion tones, and beautifully even, high-impact color.

If you’ve ever admired icy platinum, creamy beige blonde, pastel pink, or vivid copper and wondered how that level of brightness is achieved, the answer is often double process color. Let’s break down what it is, how it works, who it’s for, and how to maintain it so your color remains brilliant between appointments.

What Is Double Process Hair Color?

Double process hair color is exactly what it sounds like: a two-step coloring service designed to lift your natural pigment and then deposit a new tone.

• Step 1: Lightening (Bleaching): The first step involves using a professional lightener to remove your natural hair pigment. This process lifts your base color to create a clean canvas. Depending on your starting shade, this step can take your hair several levels lighter.
• Step 2: Toning or Glossing: After the hair is lightened, a toner, gloss, or demi-permanent color is applied. This second step refines the shade –  eliminating unwanted warmth (like yellow or orange tones) and creating your desired finish. This two-step method allows for brighter, more precise, and more customized color results than a single-process service.

Double Process vs. Single Process: What’s the Difference?

It’s important to understand how double process differs from other color services.

• Single Process Color: Lifts and deposits color in one step. Ideal for gray coverage, darkening, or subtle lightening (1–2 levels).
• Highlights/Balayage: Lightens select strands for dimension while leaving natural depth.
• Double Process: Fully lightens the hair first, then tones – often resulting in all-over brightness or dramatic color change.

If your goal is ultra-light blonde, pastel hues, or vibrant fashion shades, double process is typically the only way to achieve those results safely and evenly.

Who Is Double Process Hair Color For?

Double process color is perfect for clients who want:

• Dramatic blonde transformations
• Platinum, icy, or white-blonde tones
• Pastel shades (lavender, blush, peach)
• Vivid fashion colors (pink, blue, copper, red)
• A complete color reset
• Even brightness from roots to ends

However, it’s not a one-size-fits-all service. A professional consultation is essential to evaluate:

• Your hair’s current health
• Previous color history
• Texture and density
• Maintenance commitment

At our luxury salons, the goal is healthy, luminous lightness.

The Benefits of Double Process Hair Color

Here’s why double process remains the go-to choice for bold, beautifully executed color.

• Maximum Brightness: Double process allows hair to be lifted significantly lighter than most single process services. This makes it ideal for true platinum and icy tones.
• Precise Tone Customization: Because toning is done separately, your colorist can neutralize brassiness and fine-tune undertones with incredible precision.
• Seamless, Even Color: For clients who prefer all-over color without dimension, double process delivers a clean, uniform result from root to tip.
• The Foundation for Fashion Shades: Pastel and vivid colors require a very light base. Double process creates that blank canvas so fashion tones appear vibrant and true.
• Luxury-Level Finish: When done properly with professional-grade lighteners and bond builders, the result is glossy, high-impact color that looks editorial yet wearable.

Popular Double Process Styles to Try

Here are some of our most requested double process looks:

• Icy Platinum Blonde: A timeless classic. This cool, almost silver-toned blonde is crisp, clean, and fashion-forward. Best for those ready for regular maintenance.
• Creamy Vanilla Blonde: Softer than platinum but still luminous. A neutral blonde that feels polished and effortlessly expensive.
• Rose Gold: A delicate blush-toned blonde that combines warmth and elegance. Ideal for clients wanting something playful yet refined.
• Copper Luxe: Bright copper or fiery red requires pre-lightening for maximum vibrancy. This shade feels bold, confident, and editorial.
• Pastel Lavender or Peach: Soft pastel hues require a nearly white base. These shades are statement-making but surprisingly wearable in the right tone.
• Scandinavian Blonde: Ultra-bright at the roots with a seamless melt into lighter ends. Clean, minimal, and striking.

What to Expect During Your Appointment

Double process appointments are more time-intensive than other services, and for good reason. Here’s what typically happens:

• Consultation & Strand Test: Your stylist evaluates hair integrity and discusses goals.
• Lightening Application: Applied carefully in sections for even lift.
• Processing & Monitoring: Lift is closely monitored to protect hair health.
• Rinse & Treatment: Often includes bond-building or strengthening treatment.
• Toning/Glossing: Custom toner applied to refine your shade.
• Cut & Style: Finished with a blowout to reveal your new color.

Expect to spend several hours in the salon: luxury color takes time.

Maintenance: What You Need to Know

Double process color requires commitment. Here’s how to keep it looking fresh and healthy:

• Root Touch-Ups Every 4–6 Weeks: Because the entire base is lightened, regrowth is noticeable. Staying on schedule prevents banding and keeps the color seamless.
• Use Sulfate-Free Shampoo: Harsh cleansers strip toner and moisture. Invest in salon-quality products formulated for color-treated hair.
• Incorporate a Purple or Blue Shampoo: To combat brassiness, use a toning shampoo 1–2 times per week (as recommended by your stylist).
• Deep Condition Weekly: Lightened hair needs hydration. Use masks rich in proteins and moisture-balancing ingredients.
• Limit Heat Styling: Blow dryers and flat irons can stress already lightened strands. Always use a thermal protectant.
• Schedule Gloss Appointments: Between full services, a gloss refresh keeps your tone cool, bright, and polished.

Who Should Avoid Double Process?

While stunning, this service may not be ideal if:

• Your hair is severely over-processed
• You have extensive box dye history
• You prefer low-maintenance color
• You rarely visit the salon

For some clients, highlights or balayage may offer a softer, more manageable alternative. A professional consultation ensures the best choice for your lifestyle and hair goals.
