Extend Your Top Secret Hair Building Kit with Refills

Keep your preferred look ready to wear with these convenient refills. Designed to integrate smoothly with your Top Secret Hair Building Fiber Kit, the refill bottle helps you refresh the density and texture you chose. The compact design fits into a drawer or bag, so you can restore your fuller appearance whenever you want a noticeable yet natural enhancement.

How refills enhance a natural, fuller look

From the moment the refined keratin fibers meet thinning areas, you may notice an immediate difference in texture and density. The fibers blend with natural hair tones, helping areas like the part, crown, and edges look thicker with less visible scalp. The result aims to be subtle, confident, and true to your own hair.

• Undetectable blend with natural color tones and texture
• All-day coverage that stands up to wind, sweat, and light moisture
• New double patented Precision Applicator for precise placement
• More fibers per jar to extend wear and reduce reapplication frequency

What’s in the refill kit and how to use

This refill set is designed to extend your original hair-building routine. It includes the refill bottle, Precision Applicator with protective cap, Sifter Top, Travel Bag, and accompanying brochures. To apply, gently shake, tilt slightly, and spray fibers onto thinning areas; sweep for an even, natural look.

• Replenishes your existing kit so your daily routine stays consistent
• New applicator enables targeted, controlled fiber placement

Care, removal, and daily use considerations

Removal is simple: wash out with one shampoo. The fibers are vegan, cruelty-free, paraben-free, and hypoallergenic, designed for comfort and ease of use in a variety of settings.

Realistic results for everyday versatility

Refills support refreshing your thinning areas, concealing roots, or boosting visual density. The approach emphasizes a natural-looking result and flexible daily wear, without promising guaranteed outcomes.
