* Red pigments are stubborn: Red pigments are among the most difficult to remove from hair. They tend to linger even after multiple bleaching sessions.
* Bleaching lifts color in stages: Bleaching works by removing melanin, the pigment that gives hair its color. However, it doesn't remove all colors at the same time. Red pigments often come out before the base color reaches a pale blonde.
* Underlying pigment: Even if your current red dye is completely removed, your underlying natural hair color can still influence the final result. If your natural hair is dark, it will show through as a warm or orangey tone, making it difficult to achieve a pure blonde.
What can happen instead:
* Orangey blonde: The most likely outcome is a brassy orange or reddish blonde.
* Pinkish tones: The red pigments can react with the bleach, creating a pinkish hue.
* Uneven color: The bleaching process can be unpredictable, leading to uneven color and patches of different shades.
Here are some tips to minimize pink tones:
* Consult a professional colorist: A professional can assess your hair and advise on the best course of action. They can use specific techniques and products to minimize the chances of pink tones.
* Use a color-correcting toner: After bleaching, a toner can be used to neutralize unwanted warm tones and create a more neutral blonde.
* Use a purple shampoo: Purple shampoo can help to counteract brassiness and prevent pink tones from appearing.
* Be patient: It may take multiple bleaching sessions to achieve a true blonde, with time in between to allow your hair to recover.
Important note: Bleaching can be damaging to hair. It's essential to use a quality bleach and follow proper techniques to minimize damage.
Remember, achieving a perfect blonde after a dark red dye is challenging and requires careful planning and execution. Consulting a professional hair colorist is always recommended for the best results.
