Product Information

Full details

The Schwarzkopf LIVE Permanent Metallic Hair Dye in Blue Mercury is designed for individuals looking to achieve a bold, professional-grade metallic finish at home without the high cost of salon visits. The primary benefit is its high-intensity pigment formula that delivers a striking, light-reflecting blue sheen that lasts. A key caveat to note is that like many vibrant permanent dyes, the final result is heavily dependent on your starting hair color and condition, meaning bleaching may be required for optimal metallic accuracy.

FAQs

Do I need to bleach my hair before using this?

For the most vibrant metallic effect, starting with light or pre-lightened hair is highly recommended.

How long should I leave the dye on?

Always follow the precise timing instructions provided inside the product packaging to avoid scalp irritation or uneven results.

Can I use this over previously dyed hair?

Yes, but results may be unpredictable; a strand test is essential to see how the Blue Mercury shade interacts with your existing color.

Is this a temporary dye?

No, this is a permanent hair colorant designed for long-lasting results.

Does this product cover grey hair?

While it is a permanent dye, fashion shades like Blue Mercury are primarily designed for color intensity and may not provide total grey coverage compared to standard natural shades.

Troubleshooting

Color did not turn out as bright as the box.

Your starting hair color was likely too dark; consider using a lightener first.

Color is patchy after application.

Ensure you are using enough product and massaging it thoroughly into every strand for complete saturation.

The metallic sheen is fading quickly.

Avoid washing your hair daily and use cool water to keep the cuticle sealed and the pigment locked in.

Setup, Compatibility & Care

Before you begin, ensure you have a plastic mixing bowl, a brush, and an old towel to protect your clothing. Perform a skin allergy test 48 hours prior to full application. For care, wash your hair with lukewarm water rather than hot to prevent the metallic pigment from fading prematurely. Use color-safe shampoos that are sulfate-free to maintain the vibrancy of the blue tones. If your hair is currently processed or chemically damaged, consider a deep conditioning treatment a week before applying the dye to ensure the color lays evenly and lasts longer.
