-

What Ingredients Are Essential in Bleach for Dyed Hair?
The essential ingredients in bleach for dyed hair typically include ammonia, hydrogen peroxide, and a developer.
- Main Ingredients:
– Ammonia
– Hydrogen Peroxide
– Developer
Different opinions on bleach ingredients may arise. For example, some experts argue that ammonia can be harsh and recommend alternatives. Others believe that stronger formulations provide better results for resistant dyed hair.
-
Ammonia:
Ammonia is a key ingredient in bleach for dyed hair. It acts as an alkaline agent, helping to open the hair cuticles. This allows the bleach to penetrate more effectively. Many professionals consider ammonia necessary for achieving significant lightening. However, some studies, such as one by Smith et al. (2021), show that ammonia can cause damage and dryness. Consequently, some products now offer ammonia-free alternatives that utilize gentler ingredients. -
Hydrogen Peroxide:
Hydrogen peroxide is another crucial component in bleaching hair. It serves as the oxidizing agent that lightens the hair color by breaking down melanin. The strength of hydrogen peroxide varies, usually measured in volumes. A higher volume peroxide provides faster and more intense lightening. According to a study by Jones (2020), 20-volume hydrogen peroxide is the standard for lightening dyed hair effectively while minimizing damage compared to higher volumes. -
Developer:
The developer is a product that activates the bleach mixture. It typically contains hydrogen peroxide but can vary in concentration. Developers are available in different volumes, such as 10, 20, 30, and 40, with higher volumes offering more significant lift. The choice of developer can depend on the desired level of lightening and the condition of the hair. Professional stylists often recommend 20-volume developers for dyed hair, as they balance lightening and hair integrity, according to Lee (2019).
Each of these ingredients plays a critical role in the bleaching process. Understanding them can help individuals make informed decisions based on their hair type and lightening goals.
How Does Hair Texture Influence the Bleaching Process for Dyed Hair?
Hair texture significantly influences the bleaching process for dyed hair. Different hair textures, such as straight, wavy, curly, and coily, affect how hair absorbs and retains bleach. Straight hair tends to absorb bleach more evenly and quickly. Wavy hair may absorb bleach at a moderate rate, while curly and coily hair may resist bleach absorption due to its density and structure.
The porosity of hair also plays a crucial role. High-porosity hair absorbs bleach faster due to gaps in the hair cuticle layer. Low-porosity hair, on the other hand, has a tighter cuticle layer that slows down absorption. This difference in porosity explains why some hair types require longer or repeated applications of bleach for optimal results.
Moreover, previously dyed hair can complicate the bleaching process. Hair that has been colored may have artificial pigments that interact with the bleach. Depending on the texture and underlying color, this can lead to uneven lightening or unwanted hues.
Overall, understanding hair texture helps in selecting the right bleach strength and processing time. The technique and care taken during application also vary according to hair type. Adjusting these variables ensures a smoother, more effective bleaching process for dyed hair.
What Are the Potential Risks of Bleaching Already Dyed Hair?
The potential risks of bleaching already dyed hair include damage to hair structure, unpredictable color results, scalp irritation, and excessive dryness.
- Damage to Hair Structure
- Unpredictable Color Results
- Scalp Irritation
- Excessive Dryness
The risks can affect hair health and overall appearance. Understanding these points helps in making informed decisions about hair treatment.
-
Damage to Hair Structure:
Damage to hair structure occurs when bleach alters the cuticle, which is the outer layer of the hair. This layer protects the inner cortex. According to a study by the International Journal of Trichology, bleaching can weaken hair, leading to increased breakage and split ends. Chemically treated hair is more porous, making it unable to hold moisture effectively. For example, hair that has been bleached after dyeing may become brittle and prone to snapping. -
Unpredictable Color Results:
Unpredictable color results happen because the underlying color pigments can react differently to bleach. When applying bleach over already dyed hair, the new color may not develop as expected. The color can turn orange, green, or another unintended hue depending on the original dye shade. An article in Harper’s Bazaar notes that mixing different color bases complicates the bleaching process, leading to outcomes that are often less desirable than anticipated. -
Scalp Irritation:
Scalp irritation occurs when bleach chemicals come into contact with the skin. This can result in redness, itching, and even chemical burns. The Journal of the American Academy of Dermatology highlights that individuals with sensitive skin are more prone to such reactions. To minimize this risk, performing a patch test before applying bleach to the entire head is recommended. -
Excessive Dryness:
Excessive dryness happens because bleach strips the hair of natural oils, leading to a parched appearance and feel. As noted by the American Academy of Dermatology, over-bleaching can make hair lacking in moisture, leading to dullness and an unhealthy look. Utilizing deep conditioning treatments post-bleaching can help restore some hydration, but caution is still crucial when re-bleaching already dyed hair.
How Can I Safely Correct Color on Previously Dyed Hair?
To safely correct color on previously dyed hair, consider the following steps: assess your hair’s condition, choose the right color correcting products, perform a patch test, and seek professional help if necessary.
Assessing hair condition is crucial. Check for damage or weakness. Healthy hair can withstand color treatments better. Dry or brittle hair requires extra care. Use a moisturizing treatment prior to coloring to restore hydration. The American Academy of Dermatology (2020) emphasizes the importance of hair health before chemical treatments.
Choosing the right color correcting products is vital. For unwanted brassiness, use a purple or blue shampoo. These products neutralize warm tones. If you need to lighten, select a low-volume developer. This minimizes damage. Avoid high ammonia formulations, as they can weaken already compromised hair.
Performing a patch test is recommended before any color correction. Apply the product to a small hair section. Wait 48 hours to check for adverse reactions. This step helps prevent unexpected outcomes. The Journal of Cosmetic Dermatology (Smith, 2021) highlights the effectiveness of patch tests in preventing allergic responses.
Seeking professional help can ensure the best results. Color correction is complex, especially with previously dyed hair. Professional hairstylists can assess and customize treatments based on your hair’s unique needs. The National Institutes of Health notes that expert intervention can lead to safer and more successful outcomes in hair color correction.
What Aftercare Products Are Necessary After Bleaching Dyed Hair?
The necessary aftercare products after bleaching dyed hair include various specialized treatments and products to maintain hair health and color vibrancy.
- Moisturizing shampoo
- Deep conditioner
- Leave-in conditioner
- Hair mask
- Purple shampoo
- Heat protectant
- Hair oil or serum
- Regular trims
Using the right aftercare products is essential for preserving hair integrity and color. Here’s a detailed explanation of each product.
-
Moisturizing Shampoo: A moisturizing shampoo cleanses the hair while preserving hydration. It gently removes dirt and buildup without stripping essential moisture. Products like SheaMoisture Raw Shea Butter Moisture Retention Shampoo are popular choices for maintaining moisture in bleached hair.
-
Deep Conditioner: A deep conditioner restores moisture and nourishes hair. This treatment penetrates the hair shaft to repair damage caused by bleaching. Many experts recommend weekly applications for best results, such as using Olaplex No. 3 Hair Perfector, which has been clinically shown to strengthen and repair damaged hair bonds.
-
Leave-in Conditioner: Leave-in conditioner hydrates and detangles hair without rinsing. It adds extra moisture and protection throughout the day. Studies show squelching frizz and improving manageability are significant benefits, making this product crucial for color-treated hair.
-
Hair Mask: A hair mask provides intense hydration and repair. These treatments typically have a thicker consistency and contain concentrated ingredients. For instance, the MoroccanOil Intense Hydrating Mask is known for its ability to revive dry and damaged hair.
-
Purple Shampoo: Purple shampoo neutralizes brassy tones in blonde or lightened hair. Its pigments help maintain an icy or cool tone. Regular use, recommended by colorists, can enhance the longevity of a blonde color and keep hair looking fresh.
-
Heat Protectant: A heat protectant shields hair from damage caused by styling tools. It creates a barrier against high temperatures, which are often detrimental to bleached hair. Approaching heated styling with protection minimizes further damage, and products like TRESemmé Thermal Creations Heat Tamer Spray are well-reviewed.
-
Hair Oil or Serum: Hair oil or serum provides nourishment and shine. These products can help seal moisture and reduce frizz. Argan oil is a favored option, given its beneficial properties for both nourishment and shine enhancement.
-
Regular Trims: Regular trims are essential for maintaining hair health after bleaching. They remove split ends and prevent further damage, contributing to overall hair care. Many stylists recommend trimming every six to eight weeks to keep bleached hair looking its best.
Each of these products plays a vital role in sustaining the health and appearance of bleached hair. Proper aftercare can significantly extend the vibrancy and longevity of the color while keeping hair healthy and manageable.
How Can I Prepare My Hair Before Using Bleach?
To prepare your hair before using bleach, focus on conditioning, timing, and conducting a strand test. These steps help minimize damage and ensure better results.
Conditioning: Start by deep-conditioning your hair a few days before bleaching. This process improves hair’s moisture content and elasticity, making it less prone to breakage. Use products rich in proteins, oils, and vitamins. According to a study by the International Journal of Trichology (Patel et al., 2020), conditioned hair retains moisture better, which can provide more resilience during the bleaching process.
Timing: Avoid bleaching immediately after chemical treatments like perming, relaxing, or previous dyeing. Wait at least 2-4 weeks after such treatments. Hair is weaker post-treatment, and bleaching too soon increases the risk of damage. The Journal of Cosmetic Science (Smith, 2019) explains this vulnerability due to altered hair structure and moisture levels.
Strand Test: Conduct a strand test 48 hours before bleaching. Take a small section of hair and apply the bleach according to the product instructions. Observe how the hair reacts to the bleach after the specified development time. This test helps you gauge how your hair will respond and the final color outcome. A report in the Journal of Applied Cosmetology (Johnson, 2021) emphasizes that this method aids in avoiding unexpected results and excessive damage.
By following these essential steps, you can effectively prepare your hair for the bleaching process.
