Everybody has experienced the “Oh” moment of a vivid color being rinsed down the drain. And it may be even worse. The dirty brown finish was a disappointment after hours of labor creating a multicolored masterpiece. Read on for four frequent causes of color bleeding and Cynthia Lumzy’s advice for avoiding them so you can avoid another “oh, crap” moment.

When rinsing bright colors, the golden rule is to always, always, always use cold water because warm water is a leading cause of the color bleed. See below for details on why this is so. The cuticle will open up when exposed to hot water, allowing the majority of the newly applied dye to be easily rinsed away.

How to Prevent Hair Dye from Bleeding into Blonde: Guide

What causes hair color to bleed?

If you’ve ever colored your hair, you know that it has the potential to be a truly wonderful and life-altering experience. What happens when things are bad, though, is another matter entirely. Search the internet for “worst hair colors,” and you will get millions of results. We understand completely as color enthusiasts.

Coloring hair is a skill that requires practice and skill. It is an art but also a science. And if you remember anything from your high school or college chemistry labs, you know that even a small change can have a dramatic impact on the outcome.

1. Faulty color theory

One of the biggest transformation issues can be winding up with a hue different than you planned – say, for example, you acquire blue dye but end up with green outcomes! Because of the rules of color theory, this kind of thing can happen if the hair has been bleached and is excessively yellow before being dyed blue.

Even though there is a lot that goes into color theory, it all comes down to using the color wheel correctly. Colors that are complementary to one another blend well, whereas complementary opposites cancel out each other’s negative effects (this is why purple or violet toners are used to counteract brassy or yellow tones). 

2. Removing long-lasting color & switching shades

Only three weeks ago, you were completely smitten by your beautiful electric blue hair. By week six, though, you see that the hue has faded to a pale green. As you could expect, this is totally typical. As a “direct dye” that is applied straight to the hair, semi-permanent color is only temporary.

Even if you wash, rinse, and shampoo often, a bright, vivid color will ultimately fade. Washing with cold water and sulfate-free shampoos and conditioners will help your hair color last longer. 

3. Affected skin

It is common knowledge that hair dye works by depositing color into your hair. However, accidents sometimes happen, and if you get hair dye on your skin, it may leave a faint tint. Applying Vaseline or petroleum jelly to your neck, face, and ears before coloring your hair is the simplest technique to avoid getting color on those areas. Wearing gloves is the simplest approach to protect your hands from getting dirty or parched. 

4. Unwanted coloration after printing

Every day, your hair comes into contact with a variety of materials. Most Splat products, including the hair color, use a semi-permanent direct dye that washes away over time. This is a benefit of semi-permanent dyes. However, the color molecules in your hair are constantly being ‘loosened’ by your interaction with water. This is why it’s not uncommon for stains to reappear on pillowcases, chair seats, and shirt collars, even after multiple items of washing.

5. Watermarks in the Bathroom

No one wants their newly remodeled, porcelain, or tile shower to look like a rainbow after washing out their hair color. But stains can and do occur. Don’t worry; Splat has a great idea for you to clean those pesky shower and tub stains. In place of bleach, try using a cleaner with hydrogen peroxides, such as Clorox Bathroom Foamer or Lysol with Hydrogen Peroxide. 

How to stop hair color from bleeding into blonde? 

How to Prevent Hair Dye from Bleeding into Blonde: Guide

For optimal lightening of your would-be blonde clients’ hair, slicing procedures are a quick and reliable method. However, it can be scary to try if you’re afraid about the foil bleeding. That’s why we watched the video above, in which Olivia Smalley, a Joico Brand Storyteller, shares her secrets while demonstrating a brilliant new way to slice hair.

1. Make it easy on yourself to succeed

To prevent breakage and provide an even lift, spray the client’s hair with Joico Defy Damage Pro Series 1 Bond Protecting Spray. It helps equal out porosity and reduces breaking, giving you a solid foundation from which to launch your business.

2. Use extremely thin slices

Olivia said that although the word “slice” connotes a substantial cut, in practice, it should be quite thin and transparent. If the portion is excessively thick, there may be leakage between the foils.

3. Prepare a proper lighter mixture

If you see bleeds in your foils, it could be due to the method you’re combining the lightener. Olivia never whips the Joico Blonde Life Lightening Powder; instead, she stirs it gradually to a toothpaste-like consistency. Why? When you whip the lighter, you introduce oxygen, which causes the lighter to expand and eventually leak through the foil. When applying a lightener, it’s important that it has a paste-like consistency so that it stays put.

4. She needs to maintain her composure

There will be a visible expansion in the foil directly at the client’s scalp if her head is really heated, which could lead to abrasions and even bleeding. Keep the salon at a comfortable temperature, but not too hot (she can overprocess) or too chilly (it might take forever).

5. You need to use a low developer

Olivia warned against immediately switching to a louder volume setting, such as 30 or 40. More oxygen is added to the lightener in higher volume developments, which results in a faster lift, but may cause the lightener to expand in the foil. You should begin with a modest developer and gradually increase it as you progress.

6. The key to everything is tension

Tighten the foil all the way to the base to prevent it from slipping and breaking. Place the foil flat against your head. To secure the foil, Olivia employs a pinkie-pointer technique (demonstrated in the video) that she says “locks it in tight.”

7. Use your brain’s circular motions to your advantage

Because of the form of the skull, foils can bleed if they are pushed too far past the round of the head. You can avoid this by thinking in a circular fashion. Keep in mind that when applying for extensions, they should never go past the round of the head. If you want to foil using a slicing method, use the same principles.

What to do if your hair color has already bled?

How to Prevent Hair Dye from Bleeding into Blonde: Guide

Coloring your hair is a purely chemical process. It’s all about the chemical reactions between your hair’s pigments and the dye’s pigments, as well as those between the peroxide and ammonia, which you use to lighten the color. We have learned from past experiences that drugs are almost never beneficial. Let me explain why:

1. Excessive analyses

Ammonia or compounds that react similarly to it are commonly found in permanent hair colors, along with peroxide. Because ammonia penetrates the hair shaft and peroxide neutralizes (or bleaches out) the natural color in your hair, both substances work together to remove color. Damage to your hair occurs when the cuticles of your hair are opened so that the bleach can penetrate the cortex and remove your hair’s natural pigment.

2. Symptoms of allergies

Permanent hair colors contain paraphenylenediamine, a common allergy, which may explain why some people experience adverse reactions after dyeing their hair. PPD and other compounds included in dyes can trigger severe reactions in people who suffer from contact dermatitis. Hair dyes should be avoided by anyone who has a skin disease, including eczema and psoriasis.

3. Impact on fertility

However, studies have contradictory results. Despite the claims of a few studies, hair dyes may not have an impact on fertility or pregnancy because of their low systemic absorption. Although long-term exposure studies are inconclusive, they do suggest that women who are pregnant or trying to conceive should avoid using hair colors.

4. Upkeep

This isn’t strictly speaking a negative consequence, but it may make some people uneasy. Many individuals have no idea how much work is involved in maintaining color-treated hair. It’s a long-term commitment that might be taxing on your hair because you’ll need to visit the salon frequently. If you dye your hair, you’ll need to find items designed for that purpose. 

5. Conjunctivitis

If you aren’t careful, the harsh chemicals used to color your hair could get on your skin and eyes, causing serious irritation. Hair colors include chemicals that, if they go into your eyes, can cause conjunctivitis, also known as pink eye. Occasionally, it causes inflammation and excruciating pain.

6. Asthma

A strong allergic reaction to hair colors can cause a variety of symptoms, including asthma. Harmful effects on the respiratory system, including asthma episodes, have been linked to prolonged exposure to the chemicals in hair colors.

7. Cancer

In the beginning, permanent hair dyes contained hazardous ingredients (cancer-causing.) While these compounds have been removed from the formulae, the question of whether hair dyes cause cancer still remains. Rather, more studies are needed to confirm a causal relationship between using permanent hair dye and an increased risk of cancer.

Why is my permanent hair dye bleeding? 

The number one rule for rinsing vivid colors is to always, always, always use cold water, as using warm water might cause the colors to run. Let me explain why: Due to the cuticle being opened by the hot water, a large amount of the newly applied dye will be washed away.

Hair dyes that are particularly vivid may fade more quickly than those with more natural tones. Our semi-permanent hair dyes are loaded with pigment for rich, long-lasting color.

What products to avoid to preserve your color from bleeding? 

I get questions and feedback on this issue every single day. Regularly, I am asked, “How do you stop that from bleeding?” both “That’s going to look beautiful until she washes it” and “That’s going to look fantastic forever” Almost always, I post a photograph with a variety of hues.

Why this occurs, I can’t say. In reality, there are a number of simple solutions to this issue. To begin, I’ll say that I make use of color placement, so bleeding isn’t always a problem and is sometimes even desirable in order to achieve a wider tonal gamut. This essay’s topic is vastly different from what will be covered in subsequent essays.

1. To put it simply, she hasn’t done her homework

Indeed, you have captured the essence of what I want to convey. In the month of February, you can slow the loss of hair color by using a pre-rinse product like Matrices. To rephrase, I have included all of the following: keep Me Vivid Color Lamination Spray, which is formulated to prevent color loss and also imparts a glossy finish to hair. Apply Color Lamination Spray after washing and conditioning, then wait a minute before rinsing. 

2. Why isn’t the water chilly enough?

Never, ever, ever use warm water to rinse fluorescent dyes. When washing bright colors, this is the golden rule. As a result of this very fact: Hot water can be used to open the cuticle, allowing for easier removal of the pigment. If you want to prevent your hair color from fading, use cold water to seal the cuticle.

3. Doesn’t it ever slow down

We’ve already established that exposure to the heat of any kind causes colors to run and fade quickly. Cynthia sometimes uses heat to enhance her semipermanent colors, but afterward, she must wait at least 10 minutes for them to calm down. Alternatively said, “the more time, the better.”

4. Set aside some time to let her hair breathe

When your client sits down at the sink, in what specific order do you begin running your hands over her hair? This is not the proper way to rinse fashion colors. Cynthia says it’s best to let the water cool the hair first; then, you may comb it.

5. Accent-color hair dye

When compared to brown and black, red, pink, and violet are more likely to bleed. Lighter shades don’t penetrate the hair shaft as deeply as darker ones because their color molecules are larger. Because of this, the color of your hair will fade more quickly.

How do you prevent one hair from being stained by the colour used on another?

When you use conditioner, you can prevent the color from migrating to your lighter hair. Conditioner should be applied to lighter hair before dying to prevent damage. Rinsing out the dye will reduce the dye’s interaction with your hair because the conditioner will function as a barrier.

What can I do to prevent my dye from running?

To keep colors bright, use a cup of vinegar in the last rinse or a half cup of salt in the wash. Take precautions against dye bleeding by using color-catcher sheets in the washing machine. Don’t cram too much into that dryer! Clothing will dry more quickly.

How do you protect dyed hair?

When you wash your hair with hot water, the cuticle layer opens, allowing shampoo and conditioner to penetrate more deeply. However, this also allows for more shedding of pigment particles. Using cold water after dying your hair can help it retain its color since it seals the cuticle.

This hair dye keeps bleeding; what gives?

Since the water that is too warm is a leading cause of color bleed, it is imperative that you follow the golden rule of rinsing bright colors: always, always, always use cold water. To explain, these are the reasons why: In order to remove much of the dye you just put on, you should run your hair under hot water to open the cuticle.

What exactly does it imply when colors “bleed” into one another?

When a piece of cloth gets wet, the dye is leached out of the fibers, causing the garment’s color to bleed. It’s a common problem with washing garments in a machine, and it causes the dye to seep into fabrics it shouldn’t. Fading occurs when the fabric’s dye has been weakened by repeated washings and other forms of wear.


Truth be said, there are instances while rinsing out when you just can’t help but have the colors mix. This is especially important to remember if you have a light pastel hue like white, yellow, or lilac (or any pastel shade) in your hair since it will become contaminated if a darker, more pigmented shade is placed next to it. Though unavoidable in certain ways, you can turn it to your advantage.

The occasional bleed is not always bad. It can be used to make one-of-a-kind color combinations that appear completely planned. The key is to strategically put your colors. Consider the color yellow. Let’s say you’re interested in creating a gradient from a vivid yellow to a mellow green to a deep blue. Think about what will happen when you wash your hair if you put the blue at the top; it will travel the length of your hair, diluting the yellow.
