What Process Lightens Hair And Deposits Color In One Application?

Lightening and coloring hair in a single application is often achieved through a process called “bleaching and toning.” During this method, a bleach product is used to lighten the hair, removing its natural pigments. Then, a toner or hair dye is applied immediately after the bleaching process to deposit the desired color.

Another method for lightening and coloring hair in a single application is using a “high-lift hair color.” High-lift hair colors are formulated to both lighten and deposit color simultaneously. These products contain stronger developers that lift the natural pigment in your hair while depositing the chosen color. It’s a convenient option for people who want a significant color change without the need for separate bleaching and coloring steps.

The Science of Lightening Hair

Lightening hair typically involves using chemicals that break down the melanin, the natural pigment found in hair, to lighten the hair’s base color. The primary method for lightening hair is through the use of hair bleach or lightening agents. These products contain active ingredients, such as hydrogen peroxide, that work to remove the natural color from the hair shaft.

How Bleach Works

Bleach is a powerful chemical that oxidizes the melanin molecules within the hair, effectively decolorizing it. When bleach is applied to the hair, it breaks down the melanin, causing the hair to progressively lighten. This process can be visually observed, as hair goes through various stages of color, from dark to light, during the application of bleach.

Safety Considerations

While bleaching is an effective method for lightening hair, it is essential to exercise caution when using it. To measure hair color and developer precisely, it is advisable to consult a professional hairstylist or carefully follow product instructions when using bleach, ensuring both safety and the desired outcome. Bleach can be damaging to the hair, and if not applied correctly, it can lead to breakage, dryness, and uneven color results.

Depositing Color

Once the hair has been lightened to the desired level, it’s time to deposit the new color. This step involves applying the hair dye in the chosen shade to achieve the desired look. There are various types of hair dyes and methods for depositing color, including temporary, semi-permanent, and permanent dyes.

Temporary Hair Dye

Temporary hair dye, also known as wash-out hair color, is a non-permanent option. It provides color that typically lasts for one to two washes. This type of dye is suitable for experimenting with different shades or adding a pop of color to your hair for a special occasion. It doesn’t require a commitment, making it a fun and low-risk option.

Semi-Permanent Hair Dye

Semi-permanent hair dye offers a longer-lasting solution with color that typically fades after several weeks. It doesn’t contain harsh chemicals like ammonia, making it a gentler choice for those who want to change their hair color without the commitment of a permanent dye. However, the results may not be as vibrant or long-lasting as permanent hair dye.

Permanent Hair Dye

Permanent hair dye is the most long-lasting option. It contains ammonia and other chemicals that open the hair cuticle to allow the color molecules to penetrate deeply into the hair shaft. Once the color is deposited, it can only be removed by growing out the hair or using additional chemical treatments. This type of dye is ideal for those who want a significant and lasting change in hair color.

Lightening and Depositing Color

The dual process of lightening hair and depositing color in a single application offers a convenient solution for achieving a new hair color without the need for separate treatments. This process is commonly used when a person with dark hair wants to achieve a lighter hair color, such as blonde or pastel shades. Here’s how it works:


Before beginning the dual process, it’s crucial to assess your current hair color and select the desired shade. It’s also essential to gather all the necessary products, including bleach, developer, and hair dye in your chosen color.


Divide your hair into sections to ensure even coverage. This will help you apply the bleach and dye more precisely.


 Start by applying the bleach to the sections of your hair. Follow the instructions provided with the bleach product, including the recommended development time. The bleach will lighten your hair to a level where it’s ready to accept the new color.


After the bleach has processed and reached the desired level of lightness, thoroughly rinse it out. You may also need to use a clarifying shampoo to remove any residual bleach.

Depositing Color:

 Lightening and Depositing Color

 With your hair pre-lightened, it’s time to apply the hair dye in your chosen color. Follow the instructions for the specific dye you are using, and make sure to evenly coat all the sections of your hair.

Development Time: 

Allow the hair dye to process for the recommended time. This time can vary depending on the type of dye you are using, so be sure to read the instructions carefully.

Rinsing and Maintenance:

 Rinse out the hair dye, and follow any additional instructions for post-dye care, such as using a color-safe shampoo and conditioner.

Advantages of the Dual Process

The dual process of lightening hair and depositing color in one application offers several advantages for those seeking a dramatic hair color change:


Performing both steps in one application can save time and effort. Instead of waiting for the hair to lighten, rinsing, and then applying the color, you complete both processes at once.

Vivid Results

When hair is lightened before applying color, the new shade tends to appear more vibrant and true to the expected result. The lightened base allows the new color to shine through without interference from the underlying pigments.

Greater Versatility

The dual process opens up a wide range of color possibilities, especially for those with darker hair. It enables you to explore shades that might not be achievable with a single-step process.

 Long-Lasting Color

By lightening the hair first, the new color is more likely to adhere to the hair shaft, resulting in a longer-lasting and fade-resistant color.

Potential Challenges and Considerations

While the dual process can be highly effective, there are some challenges and considerations to keep in mind:

 Hair Damage

Both lightening and dyeing processes involve chemicals that can potentially damage the hair. It’s crucial to take steps to minimize damage, such as using high-quality products and following proper care routines.


Maintaining the vibrancy and health of colored hair requires regular touch-ups and the use of color-safe hair products. Be prepared for ongoing maintenance to keep your hair looking its best.

Professional Assistance

For complex color changes or if you’re unsure about the process, it’s advisable to seek the expertise of a professional hair colorist. They can provide guidance and ensure the best possible outcome.

Allergic Reactions

Always perform a patch test before using any new hair products to check for allergic reactions or sensitivities to the ingredients.
