Minute Hair Hair Building Fibers Refill — Black 100 g, fits Toppik/Xfusion bottles, instant fuller-looking hair

These refill fibers fit most applicator bottles and work with competitor dispensers such as Toppik or Xfusion, offering a quick, non-permanent way to reduce the visible contrast between hair and scalp. The fibers are designed to cling to existing strands by static, blending with your natural hair color and adding surface density until the next wash. They’re perspiration- and wind-resistant when sealed with a strong hair spray and remove easily with shampoo.

How do I apply Minute Hair fibers for a natural finish?

Begin with dry, styled hair and apply the fibers from the back of the thinning zone toward the front, following your natural hairline. Dispense fibers by shaking or inverting your bottle and gently pat the treated area to integrate the fibers with your hair. Avoid brushing directly at the roots immediately after application to keep fibers in place.

• Start with dry hair and finished styling for best blending.
• Shake or turn the bottle and lightly tap to release fibers.
• Pat gently after applying to distribute fibers evenly.
• Lock in place with a strong hairspray or Minute Hair fiber hold spray.

Will these fibers work with my existing applicator bottle?

The 100 g refill is sized to refill common fiber dispensers and is compatible with many brands’ bottles, including popular competitor applicators. If your bottle uses a standard neck opening or shaker lid, you should be able to transfer the product easily. Keep spare bottles or funnels handy for clean refills.

• Designed as a refill compatible with most applicator bottles.
• Works with Toppik, Xfusion-style dispensers in most cases.
• Use a clean funnel or spare shaker for neat transfers.
• Store remaining fibers in a cool, dry place to preserve texture.

How long do the fibers last and how are they removed?

Minute Hair fibers provide a temporary cosmetic result that lasts until you wash your hair. They withstand normal perspiration and light wind when sealed with hairspray but are not permanent. To remove, simply shampoo and rinse—no special solvents are required.

• Temporary coverage that washes out with shampoo.
• Improved resistance with a strong hair spray or fiber hold spray.
• No clogging of pores; fibers are formulated to be hypoallergenic.
• Reapply anytime to refresh coverage or correct movement.

Which color and quantity should I choose for best results?

The refill comes in black and is suitable for users with dark natural hair seeking high-coverage refill supply. A 100 g pouch is ideal if you use fibers regularly or need enough product to refill multiple bottles. Minute Hair offers additional colors if you need a closer match to your natural shade.

• Black is best for naturally dark or dyed hair shades.
• 100 g provides multiple refills for extended use.
• Available in 10 colors across the Minute Hair range for precise matching.
• Keep a small tester bottle to dial in the right amount per application.

Who is this for?

This Minute Hair 100 g refill is aimed at men and women who want a fast, non-invasive way to reduce the appearance of thinning or to add temporary density for photos, events, or everyday confidence. It suits people who prefer cosmetic solutions over surgical or pharmaceutical options, those who already own a fiber applicator bottle (including many competitor brands), and anyone seeking a portable, washable concealer that blends with natural hair.
