What Happens When You Put Purple Dye over Green Hair?

When you put purple dye on green hair, the resulting color will likely be a mix of the two shades, which could range from a greenish-blue hue to a bluish-green shade. However, the final outcome depends on factors like the shades of green and purple, the use of a developer, and the health of your hair:

Shades of Green and Purple

The base shade of green and the shade of purple you choose will affect the final color. A light purple dye might give you a greenish-blue hue, while a dark purple could initially cover the green and then gradually turn into a bluish-green shade after a few washes. 

In some cases, you might want to experiment by directly mixing purple and green hair dye. This can lead to unique results, such as creating a custom shade that falls somewhere between the two original colors. For instance, mixing a deep emerald green with a rich violet may yield a captivating shade of blue-green that complements your style.

Developer Usage

Using a developer can help you achieve the desired shade of purple by opening the hair cuticles(1) and removing the existing green color. However, a strong developer might be harsh on your hair, so it's essential to choose the right strength.

Your Hair Health

The overall health of your hair plays a significant role in how well the purple dye will cover the green hair. Healthy hair is more likely to accept the new color evenly.

Color Theory

Purple dye will not tone green hair because purple is opposite of yellow on the color wheel, which means it cancels out yellow, not green. If you're looking to cancel out green hair, consider using a red shampoo or color depositing dye, as red is opposite of green on the color wheel. While purple dye can cover green hair effectively without bleaching, the outcomes may vary, making it crucial to understand color theory and how different colors interact with each other.

How to Put Purple Dye over Green Hair

If you're ready to put purple dye over your green hair, follow these steps for a smooth process and the best results:

  1. Choose the right shade of purple: Consider your current green shade and the desired outcome when selecting a purple dye. Light or dark shades of purple may yield different results.
  2. Gather necessary supplies: In addition to the purple dye, you'll need gloves, a mixing bowl, an applicator brush, hair clips, a timer, and an old towel or shirt to protect your clothes from staining.
  3. Prepare your hair: Ensure your hair is clean and dry before applying the dye. This will help the color adhere evenly and provide better results. Divide your hair into sections using hair clips for easier application.
  4. Apply the purple dye: Wearing gloves, mix the dye according to the package instructions. Use the applicator brush to apply the dye to each section of hair, starting at the roots and working your way down to the ends. Make sure to saturate your hair evenly with dye to avoid patchy results.
  5. Process the dye: Once you've applied the dye to all sections, set a timer for the recommended processing time (usually around 40 minutes). This time may vary depending on the brand of dye, so follow the package instructions.
  6. Rinse and condition: After the processing time has elapsed, rinse your hair thoroughly with lukewarm water until the water runs clear. Apply a color-safe conditioner to help seal the cuticles and add moisture back to your hair. Let it sit a few minutes and then rinse it all off.
  7. Dry and style: Gently towel-dry your hair, then use a hairdryer on a low heat setting or let your hair air-dry. Once dry, style your hair as desired.
  8. Maintain your new color: To keep your purple hue vibrant, touch it up every 4 weeks, depending on the shade. Use color-safe shampoos and conditioners to prolong the life of your new color, and consider using a purple shampoo to maintain the vibrancy.

Other Colors to Dye over Green Hair

If you're looking to change your green hair color but are unsure about going purple, you might be wondering what color to dye over green hair. Let's explore some alternative colors that can work well over green hair:

Blue

A strong shade of blue can yield better results than purple when applied over green hair. The combination of blue and green can create a vibrant teal or turquoise shade, depending on the intensity of both colors. Keep in mind that if your base green color is too dark, you might need to remove it before applying blue dye.

Red

Though red dye can be used over green hair, it may not give the desired results, as red and green are complementary colors that cancel each other out. If you still want to try red, use a hair color remover to strip the green dye before applying the red color.

Dark Shades

Dark brown, black, dark blue, or dark purple are all options for covering green hair. These colors tend to have more pigment, which helps to mask the green hue effectively. However, these darker shades may require additional maintenance to keep them looking fresh.

Bright Colors

Some bright colors, such as bright blue or pink, can work well when applied over green hair. They may create unique and eye-catching results, but be prepared for potential color mixing and unexpected outcomes.

When selecting a new color to dye over green hair, it's essential to consider the base shade of green, the new color you're aiming for, and how the two colors will interact. Experimenting with different shades can lead to unique and fun hair colors, but always be cautious and perform a strand test to ensure the desired outcome.

Safety & Precautions

Dyeing your hair a new color can be an exciting adventure, but it's essential to take certain precautions to protect your hair and achieve the best results. Here are some helpful tips to keep in mind when transitioning from green hair to a different color:

Strand Test

Before dyeing your entire head, always perform a strand test. Apply the new dye to a small section of hair, following the product's instructions. This will give you an idea of how the color will look and help you avoid any unwanted surprises.

Hair Color Remover

If you're changing from a dark green base or if your chosen color may not cover the green effectively, consider using a hair color remover. This will strip the green dye, making it easier to achieve your desired color.

Use a Developer Cautiously

Using a developer can help you achieve the desired shade by opening the hair cuticles and removing the existing green color. However, a strong developer can be harsh on your hair, so use it cautiously and follow the product's instructions.

Bleaching With Care

If you're aiming for a lighter color, like blonde, you may need to bleach your hair first. Just be aware that bleaching can damage your hair(2), especially if multiple sessions are required. Always be cautious when trying to bleach your own hair and consider seeking professional assistance if you are unsure.

Maintain Hair Health

Changing hair color can be taxing on your hair's health. Ensure you're using the right products, such as conditioners, hair masks, and heat protectants, to maintain your hair's strength and vitality.

Touch-Ups

Depending on the shade and color of your new dye, you may need to touch up your hair every 4 weeks or so. This will help maintain the vibrancy and evenness of the color.

Final Thought: Can I Put Purple over Green Hair?

The answer is yes, you can! However, it's crucial to keep in mind that the final result will depend on various factors, such as the shades of green and purple, whether a developer is used, and the health of your hair. By understanding color theory, following the precautions we've outlined, and being open to experimenting with different shades, you can successfully achieve a fresh new look that complements your style.
