* Green usually comes from brassiness: Green tones in hair usually occur when bleached hair is not toned properly. Bleaching lifts the natural pigment out of your hair, leaving it more porous and susceptible to picking up unwanted tones, like green.
* Dark hair needs multiple steps: Going from dark to light typically requires multiple bleaching sessions. This process removes the dark pigment gradually, reducing the chance of green tones developing.
* Proper color correction is key: If green does appear, it's usually a result of an incorrect toner or improper application during the bleaching process. A skilled hairdresser can easily correct this with the right toner or color correction techniques.
Here's what you should keep in mind:
* Always consult a professional: Dyeing your hair from dark to light is a complex process, especially if you're aiming for a very light blonde. A professional stylist can assess your hair type, color, and condition to recommend the best approach.
* Use high-quality products: Choose reputable hair dye brands and ask your stylist about the products they use. This helps ensure the best possible results.
In short: While green tones are possible in some cases, they're not a typical consequence of going from dark to light with proper techniques.
