Understanding Hair Dye Types
First, it’s important to understand the different types of hair dye. There are two kinds: semi-permanent and permanent. Semi-permanent dye gradually fades as you wash it, whereas permanent dye modifies the hair structure. Black hair dye, regardless of the kind of dye used, almost always bleeds into blonde hair. This is because the molecular structure of black hair dye makes it easier for the dye molecules to seep through the cuticles of hair shafts and into different colors.

Preventing Bleeding from Semi-Permanent Dye
To stop black semi-permanent dye from bleeding into blonde hair, use a sulfate-free shampoo, wash your hair less frequently, and use cold water to wash your hair. Sulfate-free shampoo is gentler on hair and won’t strip the color as quickly as regular shampoo. Washing your hair less often will also help to prevent the color from fading or bleeding. Cold water will help to keep the cuticles of your hair shafts closed, preventing the dye molecules from seeping out.

Preventing Bleeding from Permanent Dye
Black toning shampoo can be used to stop the permanent black dye from bleeding into blonde hair. This type of shampoo has pigments that help to neutralize the color and prevent it from bleeding into other colors. Additionally, using a good quality color-safe shampoo when washing your hair and rinsing with cold water will also help to prevent bleeding.
Avoiding Damage to Hair Color
The heat from hot water or styling tools and the sun’s rays can damage black hair dye, causing it to fade faster. To protect your hair color from fading or bleeding, use products designed specifically for colored hair such as protective sprays or leave-in conditioners, and avoid over-washing your hair. When you do wash your hair, use cold water and be gentle when shampooing and conditioning.
Preventing Bleeding with Highlights
Hair color bleeding into blonde can also be a problem when highlights with bleach are applied to the hair and a base color is used to color regrowth. This occurs when one color formulation amalgamates into another color formulation causing unwanted results. When applied, bleach opens the hair cuticle and consumes the embedded color pigments held within the hair cuticles. To limit the risk of bleeding, it is recommended to ensure 6-8mm of clearance between the application of bleach in highlights and the edge of the foil. Limit the movement of highlights in foils after application, and avoid applying pressure to the highlights in the foil when checking the highlight color. In case hair color bleeding has already occurred, it is important to periodically check the processing color to ensure there is no bleeding occurring. Scrape excess bleach off the scalp/color area with a tail comb without interrupting any other highlights. Mix up a little more of the base color and apply it gently to the area. Add an additional 15-20 minutes of processing time for the newly applied color to process adequately.

Using an Intermediate Dye
Professional knowledge suggests using an intermediate dye to fill the color before using black dye on very light hair to prevent bleeding. An intermediate dye will add a layer of color to your hair before applying the black dye, which can help prevent the black dye from bleeding into the blonde areas of your hair.
Clarifying Shampoo for Bleeding
If black hair dye has already started bleeding into blonde, apply to clarify shampoo directly onto the affected areas and rinse with cold water. Clarifying shampoo can help remove the excess dye that has bled into the blonde hair. It is important to rinse with cold water to help close the cuticles of your hair shafts and prevent further bleeding.

In conclusion, preventing black hair dye from bleeding into blonde hair requires some effort, but it is possible with the right techniques and products. Understanding the different types of hair dyes and how they interact with your hair is essential. Using sulfate-free shampoo, washing your hair less frequently, and using cold water can help prevent bleeding from the semi-permanent dye. For permanent dye, black toning shampoo, good quality color-safe shampoo, and cold water can help prevent bleeding. Protecting your hair color from damage caused by heat, sunlight, and over-washing is also important. Finally, using an intermediate dye or clarifying shampoo can help to fix any bleeding that has already occurred.
