* Your natural hair color matters: The darker your natural hair color, the more difficult it is to achieve a blonde shade with permanent dye. Very dark hair may require multiple rounds of bleaching before you can even get to a light blonde.
* The type of permanent dye: Some permanent dyes are designed for lifting darker hair, while others are for toning or adding highlights.
* Your hair's condition: Damaged or porous hair can be more susceptible to color changes, but can also be more likely to break or become unevenly colored.
* The developer's strength: The developer in the dye determines how much lifting power it has. A higher developer will lift the color more dramatically but can also cause more damage.
Here's a more accurate way to think about it:
* Lightening: Permanent blonde dye can lighten your hair, but the degree of lightness will depend on your natural color and the dye's formulation.
* Toning: Once you've lightened your hair, permanent blonde dye can also be used to tone it, adding subtle shades of blonde, like ash blonde or golden blonde.
It's always best to consult a professional stylist! They can assess your hair and recommend the best approach to achieve your desired blonde color safely and effectively.
