Top Secret Hair Thickening Fibers with Applicator – Light Brown (Travel Size)

Instant fullness with a natural look

Top Secret Hair Thickening Fibers use plant-based keratin to help thinning areas appear fuller. Designed for both men and women, these fibers blend with your existing hair for a seamless, natural texture. The kit includes the fibers, a Precision Applicator with a protective cap, a sifter top, a travel bag, a brochure, and a paper clip.

Precision, blending, and color that fits your routine

Colors are developed with input from a world-class hair expert, ensuring the fibers blend with common hair tones. The result is a believable fullness that can help conceal roots and light scalp visibility, while supporting a low-maintenance color routine.

• Undetectable blending in daylight and movement
• Vibrant, true-to-tone shade options
• Easy reapplication as needed

All-day coverage for busy days

Effortless application and care

The U.S. patented Air-Burst Precision Applicator provides controlled bursts to minimize clumping. It is designed for tidy storage, with a protective cap and a compact form that is easy to carry. The kit can also be used to enhance eyebrow or beard areas.
