can you mix different brands of hair color and developer

When it comes to hair coloring, many people wonder whether it is possible to mix different brands of hair color and developer. The answer to this question depends on various factors, including the ingredients, formulations, and compatibility of the products. In this article, we will explore this topic in detail and provide you with all the information you need to know about mixing different brands of hair color and developer.

Understanding Hair Color and Developer

Before delving into the topic, it is important to have a clear understanding of what hair color and developer are. Hair color is the product that is used to change the shade or color of your hair, while the developer, also known as the oxidizing agent, activates the hair color molecules and facilitates the color transformation process.

The developer comes in different volumes, such as 10, 20, 30, and 40, which determine the strength and speed of the color development. Mixing the right proportions of hair color and developer is crucial to achieve the desired results and minimize potential damage to your hair.

Factors to Consider when Mixing Different Brands

1. Compatibility: Different brands of hair color and developer may have different formulations and ingredients. It is important to ensure that the products are compatible with each other to avoid any adverse reactions or undesirable results.

2. Similarity in Formulations: If you are considering mixing different brands, it is recommended to choose products with similar formulations. This increases the chances of achieving better results as the ingredients are likely to work well together.

3. Professional Advice: If you are unsure about mixing different brands, it is always best to consult a professional hair colorist or stylist. They have the knowledge and experience to guide you and provide personalized recommendations based on your hair type, color goals, and the specific products you wish to mix.

The Risks of Mixing Different Brands

Mixing different brands of hair color and developer can pose certain risks, including:

  • Inconsistent Results: Different brands may have different color tones, pigments, or levels of intensity, which can lead to unpredictable results.
  • Color Fading or Oxidation: Incompatibility between the hair color and developer can result in color fading or oxidation, where the color may change over time and not retain its original vibrancy.
  • Hair Damage: Using incompatible products or incorrect ratios of color and developer may result in hair damage, such as dryness, breakage, or loss of shine.
  • Allergic Reactions: Some individuals may be sensitive or allergic to certain ingredients present in different brands. Mixing products from different brands increases the risk of allergic reactions.

Performing a Patch Test

Before mixing different brands of hair color and developer, it is highly recommended to perform a patch test. A patch test involves applying a small amount of the mixed product on a small area of your skin, typically behind your ear or on your inner arm. This test helps to identify any allergic reactions or sensitivities before applying the product to your hair.

Here is a quick step-by-step guide on how to perform a patch test:

  1. Cleanse the area where you will be applying the product.
  2. Mix a small amount of the hair color and developer from the different brands as per the desired ratio.
  3. Apply a small patch of the mixture to the chosen area.
  4. Leave it on for the recommended time stated on the hair color packaging or as advised by a professional.
  5. Observe the area for any signs of redness, itching, swelling, or irritation for the next 24 to 48 hours.
  6. If any adverse reaction occurs, do not proceed with using the mixed products.


In conclusion, while it is possible to mix different brands of hair color and developer, it is crucial to consider factors such as compatibility, formulation similarities, and seek professional advice. Mixing products from different brands can lead to inconsistent results, color fading or oxidation, potential hair damage, and allergic reactions. Performing a patch test is advisable to identify any sensitivities before applying the mixed products to your hair. Always prioritize the health and safety of your hair, and consult professionals when in doubt.
