That’s where the expertise behind a professional double process hair color comes in. This isn't just about applying bleach; it's a careful, two-step method of lifting your natural pigment and then toning to the perfect shade, all while protecting the integrity of your hair. When done correctly, you can absolutely achieve your dream color without sacrificing softness and shine. Here, we’ll explain our approach to healthy lightening and share our best tips for at-home care.

What Is a Double Process Color?

If you’ve ever dreamed of a dramatic hair color change—like going from dark brown to platinum blonde or adding a vibrant fashion color—you’ve probably heard the term “double process.” It sounds technical, but it’s actually pretty straightforward. A double process color is simply a two-step service designed to achieve a significant color transformation. Unlike a single process where color is applied once, this method involves two separate applications to create your final look. It’s the secret behind some of the most stunning hair colors you see.

Breaking Down the Two-Step Process

So, what exactly happens during those two steps? It usually follows one of two paths. The most common method involves lightening the hair first, often using a lightener to lift your natural color to the perfect level. After rinsing, the second step is to apply a toner, gloss, or a new color to achieve the specific shade you’re looking for. Another way to do a double process is to apply one color and then follow it up with a second color—like a permanent base with a demi-permanent gloss over it—to create a rich, multi-dimensional result.

When Is a Double Process Necessary?

A double process is your go-to when you want a noticeable and vibrant change. It’s essential for achieving very light shades, like icy or platinum blonde, which are impossible to get with a single application on darker hair. It’s also the best method for creating a clean canvas for vivid fashion colors like pinks, blues, and purples. This technique isn't just for going lighter; it can also be used when making a drastic shift from light to dark, ensuring the new, deeper color looks even and lasts longer. Our stylists specialize in creating these kinds of beautiful, lived-in hair color transformations.

Common Double Process Myths, Debunked

Let’s clear up a few things. Many people think "double process" is just another word for "bleach," but that's not always true. While lightening is a common first step, the defining factor is the two-part application, not the specific products used. Another big concern is damage. Because this service often involves lightening, it can be more intensive on your hair than a single process. However, that doesn’t automatically mean your hair will be unhealthy. When performed by a skilled professional who prioritizes hair integrity, you can achieve a stunning new color while keeping your hair strong and beautiful.

Double Process vs. Single Process

When you hear stylists talk about "processes," they're really just talking about the number of steps it takes to get you to your dream hair color. Understanding the difference between a single and double process is the first step in figuring out what your hair needs to achieve the look you want. One is a straightforward application, while the other is a more involved transformation. Let's break down what each one means for you and your hair.

Single Process: One-Step Color

A single process color is exactly what it sounds like: a hair coloring service that’s done in one simple step. Think of it as your go-to for a consistent, all-over color. This is the service you’d book to cover grays, touch up your roots, or enrich your natural shade from root to tip. It’s a fantastic way to get a rich, uniform look without a huge time commitment. If you’re looking for a subtle change or want to maintain your current lived-in color, a single process is likely the perfect fit. It’s efficient, effective, and gives you that fresh-from-the-salon feeling.

Double Process: Lighten and Tone

A double process color is a two-step journey for your hair. This is for anyone dreaming of a major color change, especially if you want to go significantly lighter. The first step involves lightening the hair to lift out its natural pigment—this is where the bleach comes in. Once your hair is lifted to the right level, the second step is applying a toner, gloss, or color to create the exact shade you’re going for. This method is essential for achieving those stunning platinum blondes, vibrant fashion colors, or soft pastels. It requires more time and expertise, but the transformative results are absolutely worth it.

Choosing the Right Method for Your Hair Goals

So, how do you know which process is right for you? It all comes down to your hair goals.

Choose a single process if you want to:

Cover gray hair.
Go darker or add richness to your current color.
Get one beautiful, even color all over.
Stick to a lower-maintenance routine.

Choose a double process if you want to:

Go from dark to light, like brunette to blonde.
Achieve a platinum, silver, or pastel shade.
Make a dramatic and noticeable change to your hair color.

The best way to decide is to chat with a professional. During a consultation, we can talk through your vision, assess your hair’s health, and create a custom plan to bring your dream hair to life.

What to Expect at Your Double Process Appointment

So, you’re ready for a major hair transformation? We love to see it! A double process color can deliver those stunning blondes and vibrant fantasy shades you’ve been dreaming of. Since it’s a more involved service, it helps to know what’s in store before you arrive. Knowing what to expect makes the entire experience more relaxing and fun. We’ll walk you through everything, from the moment you sit in our chair to the steps we take to keep your hair healthy and gorgeous long after you leave.

Your Salon Visit, Step by Step

A double process is exactly what it sounds like: a two-step coloring treatment. First, we’ll have a thorough consultation to make sure we’re on the same page about your hair goals. The first step of the color service involves lightening your hair to create the perfect clean canvas. Once your hair has lifted to the right level, we’ll rinse it and prepare for step two: applying your target color. This could be a toner to achieve that perfect shade of blonde, a vibrant fashion color, or a rich glaze. We take our time with each step to ensure the results are even, beautiful, and exactly what you envisioned from our color services.

How Long Will Your Appointment Take?

Patience is key when it comes to a double process. Because it involves two separate applications and processing times, you should plan to be with us for a while. A typical double process appointment can take anywhere from two to four hours, sometimes longer depending on your hair’s length, thickness, and starting point. We promise it’s worth the wait! Think of it as some well-deserved “me time.” Settle in with a drink, catch up on your favorite podcast, and let us handle the magic. We’re focused on getting the details right for a flawless finish, not rushing you out the door.

Our Approach to Healthy Lightening

Lightening your hair is a chemical process, and our top priority is maintaining the health and integrity of your strands. We use high-quality products and proven techniques to protect your hair every step of the way. But great hair care doesn’t stop when you leave the salon—it’s a team effort! We’ll send you home with a personalized care plan. This includes using sulfate-free shampoos and conditioners formulated for color-treated hair, which you can find in our online store. For an extra layer of protection, we often recommend investing in a shower head filter to prevent mineral buildup that can cause brassiness and dryness.

The Results and the Investment

Going for a double process color is a commitment, but it’s one that pays off in a big way. This isn't just about changing your hair color; it's about creating a look that is uniquely you. From the initial transformation to the long-term care, understanding the full picture helps you feel confident and prepared. Think of it as an investment in yourself—one that requires a bit of planning but delivers a stunning return every time you look in the mirror. Let’s walk through what you can expect in terms of the final look, the cost, and the care required to keep it looking incredible.

The Payoff: Stunning Transformations

The real magic of a double process is its ability to create truly transformative results. Because we first lighten your hair, we create a perfect blank canvas. This allows us to then apply a toner or color to achieve a vibrant, precise shade that simply isn’t possible with a single step. This is how you get those head-turning platinum blondes, pastel pinks, or rich, dimensional tones. The two-step method ensures your new color is not only more brilliant but also more even and long-lasting. It’s the secret behind some of the most beautiful lived-in hair color looks, giving your hair depth and a flawless finish that looks and feels amazing.

Understanding the Cost

A double process service is an investment in both time and artistry, so the cost reflects that. It’s a more complex and lengthy appointment than a single process because it involves two distinct chemical services. The price accounts for the extra product used, as well as the skill and attention to detail required from your stylist to protect your hair’s health while achieving your dream color. While prices vary, you can expect it to be a higher-ticket service. The best way to get a clear idea of the investment for your specific hair goals is to schedule a consultation with us. We can discuss your vision, assess your hair, and give you a personalized quote.

Planning for Upkeep and Touch-Ups

To keep your double-processed color looking fresh and seamless, regular maintenance is key. We typically recommend coming in for a touch-up every six to eight weeks. This schedule is important because if your roots grow out too long (usually more than an inch), it can require a more intensive color correction rather than a simple root touch-up. Staying on top of your appointments ensures the process is quicker and helps maintain the integrity of your hair. We can even help you pre-book your next visit before you leave the salon, making it easy to stick to a routine. Our salon memberships are also a great way to plan for regular maintenance while enjoying extra perks.

How to Care for Double-Processed Hair

Going lighter is exciting, but it’s also a commitment to your hair’s health. Because the double process involves lightening your hair so significantly, it needs a little extra attention to stay strong, shiny, and soft. Think of it as protecting your investment. With the right care routine at home and a little help from your stylist, you can keep your hair looking and feeling incredible long after you leave the salon. A consistent routine is the secret to maintaining that fresh, vibrant color and preventing damage before it starts.

Your At-Home Hair Care Routine

The foundation of healthy double-processed hair starts in your shower. Swap your regular shampoo and conditioner for sulfate-free formulas designed specifically for color-treated hair. These gentler products cleanse without stripping your hair of its natural oils or your beautiful new color. I also recommend making hydrating products your new best friends. Incorporate a weekly hair mask, a daily leave-in conditioner, and a nourishing hair oil into your routine. You can find some of our favorite professional-grade products in our online store. These simple steps will replenish moisture and keep your hair feeling silky and strong.

In-Salon Treatments to Keep Your Hair Strong

While your at-home routine is crucial, professional treatments provide a level of repair and protection that’s hard to achieve on your own. We recommend scheduling regular deep conditioning or bond-building treatments at the salon. These services use concentrated ingredients to penetrate the hair shaft, repairing the internal structure that can be weakened during the lightening process. A gloss or toner treatment between appointments can also refresh your color and add incredible shine. Think of these in-salon treatments as a facial for your hair—an essential step to keep it in top condition.

Making Your Beautiful Color Last

To keep your color looking vibrant and true-to-tone, a few simple habits can make a huge difference. Try to wash your hair less frequently—two to three times a week is ideal—and use cool or lukewarm water, as hot water can open the hair cuticle and cause color to fade. When you do use heat styling tools, always apply a heat protectant first. Limiting heat exposure will not only preserve your color but also prevent further dryness and damage. Following these tips will help you extend the life of your color and keep your hair healthy until your next touch-up appointment.

Frequently Asked Questions

Is a double process service going to ruin my hair? This is a completely valid concern, and the honest answer is no—not when it’s done correctly. While lightening your hair is an intensive process, it doesn’t automatically lead to damage. The key is working with an experienced stylist who puts the health of your hair first. We use professional-grade products and careful techniques to protect your hair’s integrity. A great colorist will also send you home with a personalized care plan to keep your hair strong and healthy between visits.

How often will I need to come back for touch-ups? To keep your color looking seamless, we generally recommend a root touch-up every six to eight weeks. Sticking to this schedule is important because if the new growth gets too long, it can turn a simple touch-up into a more complex color correction. Staying on top of your appointments ensures the process is quicker, more consistent, and better for your hair’s overall health.

Can I get a double process if my hair has been previously colored? Yes, it’s often possible, but it does add a layer of complexity to the service. Existing artificial color needs to be removed before we can achieve a new, even result, which requires a very strategic approach. This is why a thorough consultation is so important. It allows us to assess your hair’s history and condition so we can create a safe plan to achieve your goals.

Why does a double process cost more than other color services? Think of a double process as two color appointments rolled into one. The price reflects the extended time you’ll spend at the salon, the larger amount of product required, and the advanced skill needed to perform the service beautifully. It’s an investment in a significant transformation that requires a high level of artistry and attention to detail from your stylist.

What’s the difference between a double process and getting highlights? The main difference is in the application and the final look. A double process typically involves lightening and toning all of your hair for a solid, all-over color change. Highlights, on the other hand, involve lightening specific sections of hair to add dimension and contrast against your base color. Both can create beautiful results, and the right choice simply depends on the look you want to achieve.
