Yes, you can bleach overdyed hair, but it requires careful preparation and technique to avoid damage.
The Basics of Hair Dye
Hair dyeing is a popular method for altering hair color, allowing individuals to express their personality and style. The process involves applying color to the hair cuticle, which then penetrates the cortex. There are various types of hair dye, including permanent, semi-permanent, and temporary dyes. Understanding these types is crucial when considering whether you can bleach overdyed hair.
Permanent dyes contain ammonia and peroxide, which open the hair cuticle for better color penetration. Semi-permanent dyes are less harsh and do not contain ammonia, making them easier to remove but less effective for significant color changes. Temporary dyes coat the hair rather than penetrate it, washing out after a few shampoos.
When you dye your hair multiple times or use intense colors like blue or red, the buildup can lead to a darker base than desired. This is where the question arises: Can I bleach overdyed hair? The answer lies in understanding how bleach interacts with existing dye.
Understanding Bleach
Bleach is a powerful chemical that lightens hair by removing its natural pigment. It works by breaking down the melanin in the hair shaft. While effective at lightening dark or vibrant colors, bleach can also cause significant damage if not used correctly.
Bleaching overdyed hair can be risky because:
1. Existing Damage: Overdyed hair may already be compromised due to previous chemical treatments.
2. Color Reaction: Certain colors can react unpredictably with bleach, leading to unwanted shades.
3. Porosity Issues: Overdyed strands may absorb bleach unevenly due to varying levels of porosity.
Understanding these factors helps set realistic expectations when considering bleaching overdyed hair.
Preparing for Bleaching
Before diving into the bleaching process, preparation is key to achieving desirable results while minimizing damage.
Assess Your Hair Health
First and foremost, evaluate your hair’s condition. If your locks feel brittle or look dull and lifeless, it might be wise to postpone bleaching until you’ve restored some health through conditioning treatments or trims.
Strand Test
Conducting a strand test is essential when dealing with overdyed hair. Select a small section of your hair and apply bleach according to the instructions on your product. This test will help you gauge how your specific dye reacts with bleach and what color outcome you can expect.
Gather Supplies
Ensure you have all necessary supplies on hand before starting:
- Bleach powder
- Developer (20 or 30 volume recommended)
- Mixing bowl
- Application brush
- Gloves
- Toner (if needed)
- Deep conditioner
Having everything ready will make the process smoother and more efficient.
The Bleaching Process
Now that you’re prepared, it’s time to tackle the bleaching process itself.
Mixing Bleach
Follow the instructions on your bleach product carefully. Typically, you’ll mix bleach powder with developer in a 1:2 ratio. A lower volume developer (20) is gentler on already dyed strands but may require longer processing time than a higher volume (30).
Application Technique
Start applying bleach from the ends of your hair upwards towards the roots since they tend to lighten faster due to heat from your scalp. Use an application brush for even distribution and work in small sections for better coverage.
Monitoring Development Time
Keep an eye on how your hair develops during the bleaching process. Check every 10 minutes until you reach your desired lift level but avoid exceeding 45 minutes total processing time.
| Developer Volume | Lifting Power | Best For |
|---|---|---|
| 10 Volume | Minimal lift (1 level) | Dark blonde/light brown base colors |
| 20 Volume | Moderate lift (1-2 levels) | Light brown/dark blonde base colors |
| 30 Volume | High lift (2-3 levels) | Medium brown/dark blonde base colors |
| 40 Volume | Maximum lift (4+ levels) | Very dark colors; use with caution! |
Toning After Bleaching
Once you’ve reached your desired lightness level, rinse out the bleach thoroughly with cool water—never hot! After rinsing, apply a deep conditioner or protein treatment to help restore moisture.
Toning may be necessary if brassy or unwanted hues appear after bleaching. Use a toner that suits your desired final shade; for example:
- Purple Toner: Neutralizes yellow tones.
- Blue Toner: Counteracts orange tones.
- Ash Toner: Provides cool undertones for a more natural look.
Apply toner according to product instructions and follow up with another conditioning treatment for best results.
Caring for Your Newly Lightened Hair
After going through such an intensive process as bleaching overdyed hair, proper care becomes crucial in maintaining its health and vibrancy.
Nourishing Treatments
Invest in high-quality nourishing treatments designed specifically for bleached or chemically treated hair. Look for products containing proteins like keratin that strengthen weakened strands while providing moisture balance.
