* Your hair's natural pigment: If your hair has warm undertones, the highlights could lean towards a more reddish shade, especially if the bleach used isn't strong enough.
* The developer used: A higher developer level will lift the hair color more, making it more likely to turn a bit brassy or reddish if not toned properly.
* The toner used: A toner is essential for neutralizing unwanted brassiness or yellow tones that can result in a reddish appearance.
* The stylist's experience: A skilled stylist will understand how to achieve the desired blonde shade while minimizing the risk of unwanted redness.
* The hair's condition: Damaged or porous hair can be more prone to taking on unwanted tones, including red.
Here's what you can do:
* Consult with a professional stylist: Discuss your hair color goals and ask for their advice on achieving the desired blond highlights while minimizing the risk of redness.
* Ask about toning: Inquire if a toner will be used to neutralize any unwanted tones.
* Consider a color correction: If your highlights turn out too red, you may need a color correction treatment to fix the issue.
Ultimately, the best way to avoid red highlights is to consult with a professional colorist and follow their recommendations.
