Wella Koleston Perfect 9/0 is a professional permanent cream hair color that creates a very light blonde with a true neutral tone—perfect for clean, bright blonding without leaning too warm or too cool.

Key Details

• Shade: 9/0 = Very Light Blonde / Natural
• Level: 9 (brighter than 8/0 and 88/0)
• Size: 2 oz salon tube
• Coverage: Up to 100% gray coverage
• Technology:
  • ME+ dye system for precise, true-to-tone color

What Makes 9/0 Different

• Higher level (9) = more brightness, less depth
• Compared to:
  • 8/0: lighter + more airy finish
