Product Overview

Transform your hair with MANIC PANIC Classic Siren's Song semi-permanent hair color. This striking neon blue-green shade delivers intense, long-lasting color that fades gracefully over 4-6 weeks. Whether you're going for a bold all-over look or adding vivid accents, Siren's Song is perfect for expressing your unique style. Made with high-quality, vegan ingredients and no ammonia or harsh chemicals, it's gentle on hair while providing salon-worthy results.

Key Features and Benefits

  • Vibrant Neon Blue-Green: Siren's Song is a stunning, eye-catching shade that stands out. The semi-permanent formula deposits rich color without damaging your hair.
  • Lasts 4-6 Weeks: Enjoy your bold color for weeks. The fade is gradual and predictable, allowing for easy touch-ups or color changes.
  • Vegan & Cruelty-Free: MANIC PANIC is committed to ethical beauty. This product contains no animal-derived ingredients and is never tested on animals.
  • Ammonia-Free & Gentle: Free from ammonia, parabens, and phthalates, this dye is safe for most hair types. It conditions while coloring, leaving hair soft and shiny.
  • Mixable for Custom Shades: Siren's Song can be blended with other MANIC PANIC shades to create your own unique color. Experiment and personalize your look.
  • Easy Application: The creamy consistency spreads evenly, making it simple to apply at home. No developer or mixing required.

How to Use

For best results, start with clean, dry, and pre-lightened hair. MANIC PANIC semi-permanent colors show best on blonde or pre-lightened hair. Apply the dye generously to sections of hair, ensuring full saturation. Leave on for 30-45 minutes (longer for more intensity). Rinse with cool water until the water runs clear. Avoid shampooing for 24-48 hours to allow color to set. Use color-safe shampoo and conditioner to prolong vibrancy.

Who It Is For

Siren's Song is ideal for anyone seeking a bold, creative hair color. It's perfect for fashion-forward individuals, cosplayers, festival-goers, and anyone who loves to experiment with their look. The gentle formula is suitable for most hair types, including color-treated or damaged hair, as long as it's pre-lightened. Both men and women can achieve stunning results.
