“Can I bleach my hair after dying it?” is a question many hair enthusiasts ask. Hair dye transforms our look, but sometimes, we crave change.
Bleaching after dyeing is a tricky process. One fact to remember: bleach doesn’t just lighten, it removes color.
This article will dive deep into the dos and don’ts, guiding you on the journey to your desired hair color without causing damage.
Can I Bleach My Hair After Dying It
Yes, you can bleach your hair after dying it. Hair dye and bleach work by altering the structure of your hair, but in different ways.
When you bleach your hair after dying it, it removes the color molecules from the hair shaft. At the same time, it lightens your natural color that may still be present. This allows for a more accurate recoloring.
Repeated dyeing and bleaching can cause damage to your hair over time.
The Science Behind Hair Dye and Bleach
Here is how hair dyes and bleach differ:
|Hair dye penetrates the hair cuticle and deposits color molecules into the hair shaft.
|Permanent hair dye usually contains ammonia or other alkalizing agent. This helps open the hair cuticle so the color can enter.
|Bleaching your hair involves using a bleach powder mixed with hydrogen peroxide.
|This removes natural and artificial pigments, resulting in a lighter hue. It breaks down pigment molecules contained in the hair shaft, weakening the hair structure.

- Thinness: Bleached hair can become thin, making it prone to breakage and hair fall.

How to Prepare for Hair Bleaching
Prepare your hair before bleaching your dyed hair by following these tips:
- Assess the condition of your hair. If it’s already dry or damaged, wait until it feels healthier before bleaching it.
- To ensure your hair has enough moisture, make a habit of deep conditioning at least once a week leading up to the bleaching process.
- As the day to bleach your hair approaches, refrain from shampooing for a few days. The natural oils in your scalp will provide a protective barrier against the bleach.
- Perform a strand test on a small section of hair. This will give you an idea of how your dyed hair will react to the bleach and the results you can expect.
- Follow the instructions on the bleaching kit for the strand test.
- Adjust the processing time or bleach mixture to suit your hair type and condition.
The Bleaching Process
Pick a developer to mix with the bleach powder. The developer strength varies from 10 volume to 40 volume. The higher the number, the stronger it is. For minimal damage, stick to a lower volume developer. Do not use bleach with developer over 20 volume on the scalp.
Put on gloves and mix the bleach powder with the developer. Apply the mixture evenly to the mid-lengths and ends of your hair, avoiding the roots initially, and let it process.
Keep an eye on your hair for the desired shade of lightness. If you have a warm undertone, the bleach might lift to an orange or yellow shade first. Be patient and watch the process to avoid damaging your hair.
Once you’ve reached the desired shade, rinse your hair with lukewarm water. Avoid heat styling for a few days to let your hair recover.
