Minute Hair Hair Building Fibers Refill 100g (Black) — Refillable, Hypoallergenic Instant Thinning Concealer

These refill fibers are designed to work with most shake-or-sprinkle applicators and are compatible with popular bottles from other brands like Toppik and Xfusion. The 100-gram (3.5 oz) size offers ample product for repeated applications, making it a practical choice for daily use or as a bulk refill. The fibers are hypoallergenic and formulated to cling to existing hair when used with a styling spray, providing a temporary cosmetic cover-up that washes out easily.

How do I apply Minute Hair fibers so they look natural?

Application is simple: start with dry, styled hair and apply from the back toward the hairline to avoid over-concentration at the front. Dispense fibers by shaking or inverting your bottle and tapping its side so fibers fall onto thinning areas; then gently pat to integrate them with your hair.

• Work in layers: apply a little at a time for subtle density.
• Block your forehead with your hand to prevent stray fibers from falling on skin.
• Lightly pat after application to blend and remove excess fibers.
• Finish with a strong hair spray to lock fibers in place.

Will these fibers work with applicators from other brands?

Yes — the refill format is sized and formulated to be used with many shaker-style bottles and applicators, including those from Toppik and Xfusion. If you already own an applicator you like, you can refill it with Minute Hair fibers without changing your routine.

• Refill-friendly: fits most shaker and sprinkle bottles.
• Compatible with popular third-party applicators for convenience.
• Use your existing applicator to control where fibers are placed.
• Large 100 g quantity reduces the need for frequent repurchasing.

How long do the fibers stay in place and how do I remove them?

Minute Hair fibers are perspiration- and wind-resistant when sealed with a firm-hold hairspray, so they remain in place through daily activities. They remain until you wash them out and can be fully removed with shampoo and water; fibers do not alter hair growth or clog pores.

• Use a strong hair spray or Minute Hair fiber hold spray to secure fibers.
• Fibers resist light wind and perspiration but are removable with normal washing.
• Hypoallergenic formulation suitable for sensitive scalps; does not affect hair growth.
• Reapply any moved areas as needed for touch-ups.

What colors and finish options are available, and which should I choose?

Minute Hair offers fibers in 10 different shades to match a wide range of natural hair colors; the Black refill gives the deepest tone for very dark hair. Choose the shade closest to your natural root or blend two shades for a customized match if your hair has highlights or transitional tones.

• Ten shade options provide precise color matching.
• Black gives the most coverage for very dark hair and visible contrast.
• Mix shades carefully to mimic natural highlights or salt-and-pepper looks.
• Undetectable finish blends with your own hair texture.
