Key benefits

How it works

The fibers selectively adhere to the hair shaft, filling visible gaps and creating a sense of density without altering your natural texture. When applied, they catch light and add subtle dimension, helping thinning areas appear fuller both from a distance and up close.

What you get and how to use

• Shake fibers gently over the thinning area or part line
• Lightly pat to set the fibers in place for a lasting look
• Optionally spritz with a hold spray to increase longevity in challenging conditions

The 15 g bottle is formulated for everyday use and travel, with a light grey shade designed to blend with common hair tones. It offers an easy, user-friendly experience for touch-ups and quick refreshes, whether you’re at home, at work, or on the go.
