* Bleach lifts color: Bleach works by opening the hair cuticle and dissolving the natural melanin (pigment) in your hair. It also dissolves artificial color pigments.
* Artificial color is not permanent: Even permanent hair color isn't truly permanent. The color molecules are deposited inside the hair shaft, but they can be lifted and removed by bleaching.
* Potential outcomes:
* Lifting the artificial color: The bleach will lift the artificial color, potentially revealing the underlying natural color (or what's left of it after the previous coloring).
* Unpredictable color results: Bleaching colored hair can often lead to unpredictable and undesirable results, such as brassy tones (orange or yellow), uneven color, or even green or blue hues, depending on the dyes used in the previous color.
* Damage: Bleaching already colored hair is more likely to cause damage, dryness, breakage, and increased porosity.
Important considerations before bleaching:
* Hair health: Assess the health of your hair. If it's already dry, damaged, or brittle, bleaching will likely make it worse.
* Color history: Consider the color(s) you've previously used and how long ago. Darker colors are harder to remove and may require multiple bleaching sessions.
* Professional help: It's generally recommended to consult a professional hairstylist, especially if you have a complex color history or want to avoid significant damage. A stylist can assess your hair's condition, formulate a plan, and use techniques to minimize damage and achieve the desired result.
* Strand test: If you're determined to bleach your hair at home, always do a strand test first. Apply the bleach to a small, hidden section of your hair to see how it reacts and what color you'll get.
Alternatives to bleaching:
* Color remover: If you want to remove the artificial color without as much damage, consider using a color remover specifically designed for this purpose. Color removers are generally less damaging than bleach.
* Color correction: A stylist can use color correction techniques to neutralize unwanted tones and achieve your desired color.
In summary, while bleaching will remove the color from your hair, it can be a risky process that may lead to damage and unpredictable results. Proceed with caution and consider seeking professional help.
