Minute Hair Hair Building Fibers Dark Brown 57g (Refill) — Thickening, Sweat-Resistant Concealer

Minute Hair Hair Building Fibers in Dark Brown (57 g) is a statically charged, temporary hair-thickening powder designed to conceal thinning areas and restore the appearance of fuller hair in seconds.

These refill fibers are formulated to cling to existing hair, create natural-looking density, and work with most applicator bottles — including many competitor containers like Toppik and Xfusion. The fibers are perspiration- and wind-resistant when sealed with a strong hair spray, hypoallergenic, and wash out with shampoo. This 57-gram (2 oz) refill pack supplies plenty of product to cover multiple applications and comes in a rich dark brown shade to blend with darker hair tones.

How do I apply Minute Hair fibers for the most natural result?

Start with dry, styled hair. Apply from the back toward the hairline, dispensing fibers onto thinning areas and gently patting them to settle; avoid brushing too close to the scalp so fibers remain attached to existing hair shafts. Finish by sealing with a strong hold spray to improve resistance to wind and sweat.

• Dispense by shaking or tipping the refill bottle and tapping the side with your finger.
• Block the forehead to prevent transfer onto skin during application.
• Pat lightly to distribute fibers and blend edges for a natural finish.
• Use a fiber hold spray for best longevity and environmental resistance.

Will these fibers damage my scalp or affect hair growth?

Minute Hair fibers are designed to be topical and temporary; they do not penetrate the skin or alter hair growth. The product is hypoallergenic and formulated not to clog pores when used as directed, and it removes easily with regular shampooing or during a shower.

• Topical cosmetic application only — no chemical interaction with hair follicles.
• Removes fully with ordinary shampoo.
• Hypoallergenic formula to reduce irritation risk.

How long do the fibers last and how do I make them stay put?

Fibers remain in place until you wash them out; their hold can be extended by using a strong hair spray or a dedicated fiber hold spray after application. While perspiration and strong wind can shift untreated fibers, sealing with spray greatly improves durability during day-to-day activities.

• Lasts until washed out with shampoo.
• Use a strong hold or Minute Hair fiber hold spray for best resistance.
• Reapply any areas that shift over time for touch-ups.

Can I use this refill with other brand bottles or on colored hair?

The 57 g refill is compatible with many common applicator bottles, including competitor containers like Toppik and Xfusion, making it easy to top up what you already own. It comes in 10 colors across the Minute Hair range, so choose dark brown for a close match to darker natural or dyed hair.

• Works with many standard shaker or pump fiber bottles.
• Available in multiple shades to match dyed or natural hair tones.
• Reapply as needed to maintain consistent coverage.
