Oxidizer for hair color

Oxidizer for hair color

Oxidizers, often referred to as developers, play a pivotal role in the hair coloring process. They are essential for activating hair dye and ensuring that the color penetrates the hair shaft effectively. This article delves into the purpose, types, and proper usage of oxidizers to achieve desired hair color results.

What is an Oxidizer?

An oxidizer in hair coloring is a hydrogen peroxide-based solution that reacts with permanent hair dye to initiate the color-changing process. When mixed with the dye, it opens up the hair cuticle, allowing the color to penetrate deeply. This chemical reaction alters the natural pigment of the hair and deposits new color.

Types of Oxidizers

Oxidizers come in various strengths, indicated by the volume of peroxide they contain. The choice of volume depends on the desired color result:

  • 10 Volume (3% peroxide): Used for depositing color without lifting the natural hair pigment. Ideal for same-level color changes or going darker.
  • 20 Volume (6% peroxide): The most commonly used oxidizer, perfect for covering gray hair and lightening hair by one to two shades.
  • 30 Volume (9% peroxide): Used for lightening hair by two to three shades. It’s more potent and can achieve more significant color lift.
  • 40 Volume (12% peroxide): Provides maximum lift, lightening hair up to four shades. It should be used cautiously due to its strong lightening capabilities and potential to cause hair damage if misused.

Choosing the Right Oxidizer

Selecting the right oxidizer is crucial for achieving your desired hair color while maintaining hair health. Consider the following factors:

  • Desired Color Outcome: Higher volumes are necessary for lighter shades, while lower volumes are sufficient for darker shades or color deposit.
  • Hair Condition: Damaged or brittle hair may require a lower-volume oxidizer to minimize further damage.
  • Scalp Sensitivity: Lower volumes are gentler on the scalp and are recommended for individuals with sensitive skin.

Safety and Best Practices

When using oxidizers, it’s essential to adhere to safety guidelines to protect your hair and scalp:

  • Patch Test: Always conduct a patch test 48 hours before applying the dye to check for allergic reactions.
  • Proper Mixing: Follow the manufacturer’s instructions for mixing oxidizer with hair dye to ensure effective and safe color application.
  • Application Tools: Use non-metallic bowls and utensils to mix and apply the dye to prevent unwanted chemical reactions.
  • Timely Application: Apply the mixture immediately after mixing to maximize its effectiveness.

Oxidizers are indispensable in achieving vibrant and long-lasting hair color. By understanding the different types of oxidizers and their appropriate uses, you can enhance your hair coloring experience while keeping your hair healthy and vibrant. Always prioritize hair condition and safety practices to ensure the best possible results.
