Here's why:
* Hair Health: Repeated dyeing can damage hair, making it dry, brittle, and prone to breakage.
* Color Results: Waiting allows the hair to fully absorb the previous color, which can affect the outcome of the new color.
* Color Fade: The first few washes after dyeing can result in color fading. Waiting allows the color to settle and prevents further color loss.
Exceptions:
* Toner: If you are simply using a toner to refresh or adjust your existing color, you can usually apply it sooner.
* Color Refresh: If you are using a semi-permanent color to touch up your roots or add a temporary color, you may be able to apply it sooner, but follow the product instructions.
Always consult with a professional stylist: They can help you assess your hair's condition and recommend the best timeline for re-dyeing.
