You tried to go blonde, but now your hair’s a patchy mix of yellow and orange. Maybe your roots came out too bright, or that at-home dye job left you with uneven, brassy streaks.
 
We get it—color mishaps are frustrating, and they can feel even worse when they’re staring back at you in the mirror every day. If left untreated, poor color jobs can lead to breakage, dullness, or make future coloring even harder. And trying to fix it yourself can often make things worse.
 
That’s why we offer professional hair color correction at Hāste Urban Hair Spa—a customized, expert-led solution designed to restore balance, tone, and confidence.

Whether you need to neutralize brass, fix hot roots, or transform your tone, we’re here to help you fall in love with your hair again.

What is Hair Color Correction?

Hair color correction is the professional process of adjusting the tone, depth, or shade of your existing hair color to create a more even, natural, and flattering result.

Think of hair color correction like photo editing, but for your hair. Instead of blindly starting over, a skilled colorist works with your current color to strategically and safely fix problems.

Common reasons for hair color correction include:

  • Removing brassiness (yellow, orange, or red undertones)
  • Lightening dark dye jobs
  • Fixing patchy, uneven regrowth
  • Neutralizing unwanted tones
  • Transitioning to a drastically different color

At Hāste, our stylists create personalized color correction plans based on your current color, hair history, and long-term goals. Techniques may include toning, filling, glossing, and color layering, often guided by the color wheel to rebalance undertones.

Important to know:

Hair color correction is not the same as using at-home color corrector products or purple shampoo. Professional correction is a controlled, multi-step salon process designed to protect hair integrity.

Color correction isn’t always a single-step fix. Dramatic changes may require multiple sessions, but the results are worth the patience.

Hair Color Correction Before and After: What Results Look Like

Hair color correction results can be dramatic when done correctly. Before-and-after transformations often show improvements such as:

  • Yellow or orange tones neutralized into soft blondes
  • Patchy color blended into an even, seamless finish
  • Hot roots balanced to match mid-lengths and ends
  • Overly dark or flat color restored with depth and dimension

Each correction process is different. Some transformations are achieved with a single toner or gloss, while others require careful lightening, filling, and re-toning over multiple sessions.

Common Hair Color Problems We Correct

How to Fix Brassy Highlights on Brown Hair

Brassiness is one of the most common color issues, especially after bleaching or highlighting dark hair. Brown hair contains natural pigments that range from red to orange and yellow.

When lightened, those warm undertones can emerge if the bleach doesn’t lift them enough.

Here’s what you need to know:

  • Don’t re-bleach immediately—this can worsen damage.
  • Give your hair time to recover with deep conditioning treatments.
  • Use a toning shampoo at home: Blue shampoo for orange/red tones in brown hair. Purple shampoo for yellow tones in blonde hair.

If brassiness persists, our stylists can professionally apply a toner or gloss to rebalance your color without further compromising hair health.

Hair Dye Color Correction: Fixing a Bad Dye Job

If you’ve tried to lighten your hair from its natural dark shade and are unhappy with the results, it’s best to dye it a darker shade.

We will start using a color filler. It is a technique for transitioning between different shades, a midway step between the current hue and the desired hue.

Doing this will add pigments to the strands for dimension and richness while disguising the original shade.

Then, another color will be applied to provide the results, adding depth to the mid-level filler shade we used first.

Attempting to fix this at home may result in further damage or unpredictable results. Instead, visit our team at Hāste for a professional color correction service that’s safe, strategic, and stunning.

How Long Does a Color Correction Take?

The length of a hair color correction can depend on different factors. Sometimes, a color correction is as simple as applying only the toner to brassy highlights.

Sometimes, lifting dark hair can become time-consuming, requiring more appointments.

If you only want to fix your roots, as the ends are OK, we can do it in a single process, such as color or gloss. A gloss can also help remove highlights.

However, if there is patchiness and you need to correct the tone, you will spend more hours in the salon, sometimes up to six hours. Another important thing is the health of your hair.

We recommend booking a consultation with one of our colorists today.

What to Expect at Your Hair Color Correction Appointment

We recommend arriving at the appointment with some context when discussing a color correction with your stylist:

  • Explain what you do not like about your color, like it does not flatter your skin, or is too bright.
  • Tell the hairdresser what product you used when you dyed your hair.
  • Explain to them the color you want to achieve, and bring along photos of the shades you are looking for.

Our stylists can guide you on whether the color you want is achievable or provide a workable alternative. Additionally, before heading to your color correction appointment, visit with a clean slate.

Arrive with fresh, clean hair, free from product buildup, which can affect the appearance of the color. We recommend using a clarifying shampoo.

Aftercare for Color-Corrected Hair

Your hair has just been through a transformation—now’s the time to protect it:

  • Use color-safe shampoos and conditioners.
  • Incorporate a hydrating deep conditioner or hair mask into your routine once a week.
  • Avoid hot tools or aggressive styling for the first few days.
  • Limit sun exposure or chlorine until the cuticle has closed.

We’ll also recommend a maintenance plan to preserve your fresh new look between salon visits.

FAQ

How do you remove highlights from your hair?

To remove highlights from your hair, you can apply a toner to neutralize unwanted tones, dye the hair back to your natural color, or use a color remover to strip the highlights.

How do you fix hot roots on brown hair?

When dealing with hot roots on brown hair, a color gloss or demi-permanent dye that closely matches the rest of the hair is an effective solution. It helps seamlessly blend the roots with the rest of the hair, resulting in a uniform, natural appearance.

How do you fix hot roots on red hair?

To fix hot roots on red hair, apply a darker red or copper shade that matches the mid-lengths and ends of your hair to the root area. It will help balance the color and neutralize the brighter or lighter roots.
