When it comes to experimenting with vibrant hair colors like purple, many individuals find themselves in a dilemma when they wish to change their hair color again. One common question that arises is whether it’s possible to bleach over purple hair. The answer to this question involves understanding the chemistry of hair dye, the effects of bleach on colored hair, and the potential risks and outcomes of such a procedure. In this article, we will delve into the world of hair coloring and bleaching, providing insights into what happens when you bleach over purple hair and how to achieve the best possible results while minimizing damage.
Understanding Hair Structure and Color
To grasp the concept of bleaching over colored hair, it’s essential to understand the basic structure of hair and how color is deposited. Hair is made up of a protein called keratin and is divided into three layers: the medulla, cortex, and cuticle. The cortex is where the pigment resides, and this is the layer that is altered when hair is colored or bleached. Hair color, whether natural or artificial, is determined by the amount and type of pigment (eumelanin and pheomelanin) found in the cortex.
The Chemistry of Hair Dye
Hair dye works by penetrating the hair shaft and either depositing color (in the case of permanent dyes) or coating the hair with color (in the case of semi-permanent or temporary dyes). Permanent dyes, which include most purple hair colors, contain oxidizing agents and colorants. The oxidizing agent breaks down the pigment, allowing it to penetrate the cortex, while the colorants determine the final color of the hair. Purple hair dye, being a vibrant and non-natural color, often requires a significant amount of bleach or lighter to achieve, especially if started from a darker natural color.
The Bleaching Process
Bleaching hair involves the use of chemicals to break down and remove the pigment from the cortex. Hydrogen peroxide is the common bleaching agent used in hair lighteners. The process of bleaching can be damaging because it not only removes the pigment but also lifts the cuticle layer of the hair, potentially causing dryness, brittleness, and breakage. The extent of the damage depends on the strength of the bleach used, the condition of the hair prior to bleaching, and how the hair is treated after the bleaching process.
Bleaching Over Purple Hair
Bleaching over previously colored hair, especially vibrant colors like purple, presents several challenges. The main issue is achieving an even and predictable result, as the existing color can interfere with the bleaching process. Purple dye, in particular, can be problematic because it tends to leave behind stubborn pigment residues that may not completely lift with bleach, potentially resulting in uneven or undesirable tones.
Risks and Considerations
- Unpredictable Outcomes: The combination of the purple dye and the bleach can lead to unpredictable color results. It’s not uncommon for the hair to end up with brassy, green, or other unwanted tones due to the interaction of the color pigments and the bleach.
- Hair Damage: Applying bleach over previously colored hair increases the risk of significant damage, including breakage, dryness, and frizz. The hair may become over-processed, leading to a rough texture and increased vulnerability to environmental and styling stresses.
- _porosity Issues: Hair that has been previously colored and then bleached may experience porosity issues, where the hair cuticle is lifted, making it difficult for moisture to enter or leave the hair shaft. This can lead to hair that is either overly moisturized and weighed down or dry and brittle.
Preparation and Aftercare
If you still wish to bleach over your purple hair, proper preparation and aftercare are crucial to minimize damage and achieve the best possible outcome. This includes:
Using a pre-bleach treatment to open up the hair cuticle and allow for a more even penetration of the bleach.
Choosing the right bleach for your hair type and desired outcome. Professional advice is invaluable in selecting the appropriate strength and type of bleach.
Following the bleaching process with a toner to achieve the desired shade and neutralize any unwanted tones.
Implementing a rigorous aftercare routine that includes moisturizing treatments, gentle shampoos, and minimal heat styling to help repair and protect the hair.
Alternatives to Bleaching
Given the risks associated with bleaching over purple hair, many individuals opt for alternative methods to change their hair color. These include:
Color Correction
Instead of bleaching, you might consider color correction techniques that can help adjust the tone of your hair without the need for bleach. This could involve using color deposits or glazes to shift the color in a desired direction.
Hair Color Removers
Another option is to use hair color removers before attempting to bleach or apply a new color. These products can help break down and remove some of the existing color pigment, making it easier to achieve a new color. However, they should be used with caution and under professional guidance, as they can also cause damage if not used properly.
Conclusion
Bleaching over purple hair is a complex process that requires careful consideration of the potential risks and outcomes. While it is possible to achieve a new color through bleaching, the key to success lies in understanding the chemistry of hair color and bleach, preparing the hair appropriately, and following a meticulous aftercare routine. For many, consulting a professional stylist is the best course of action, as they can provide personalized advice and treatment to minimize damage and achieve the desired results. Whether you decide to embark on this journey or explore alternative color changing methods, prioritizing the health and integrity of your hair should always be the top priority.
