Minute Hair Hair Building Fibers Refill 100 g Dark Brown — Keratin, Hypoallergenic, Wind-Resistant

Minute Hair Hair Building Fibers 100 g (Dark Brown) is a statically charged, color-matching fiber refill that instantly fills thinning areas for a thicker-looking hairline and works with many competitor applicator bottles.

This 3.5 oz refill delivers professional-grade, hypoallergenic keratin fibers in Dark Brown designed to blend with your natural hair. The product attaches to existing hair by static charge to create the appearance of density that lasts until your next wash. It’s perspiration- and wind-resistant when used with a strong hair spray, and it’s made for everyday styling routines without affecting scalp pores or hair growth.

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

Apply to dry, styled hair, working from the back forward to follow natural hairlines. Dispense fibers by shaking or inverting the refill into an applicator bottle or directly above thinning areas, then lightly pat to settle them into place. Avoid brushing the roots directly; a light combing from mid-lengths can refine the look without disturbing the fibers.

• Start from the back and move forward along hairlines.
• Shake or turn the bottle, tap to dispense fibers evenly.
• Pat gently to blend and avoid contact with roots when combing.
• Finish with a strong hairspray or Minute Hair fiber hold spray for extra hold.

Will these fibers stay put during my day-to-day activities?

The fibers are designed to resist light perspiration and wind when sealed with a quality hairspray. They remain in place through normal movement, but heavy sweating, swimming, or rubbing will remove them. Reapplication is quick and simple whenever needed.

• Perspiration-resistant with hairspray; not waterproof.
• Wind-resistant when locked with a strong hold spray.
• Lasts until you wash your hair; reapply after vigorous activity.
• Use Minute Hair fiber hold spray for best adhesion.

Is this refill compatible with bottles from other brands like Toppik or Xfusion?

The 100 g Minute Hair refill is formulated to work with many standard applicator bottles, including popular competitors. You can decant the fibers into your existing dispenser or use them with Minute Hair’s own applicators for precise coverage. Ensure your bottle opening and dispensing method match to avoid spills.

• Compatible with many standard shaker-style applicators.
• Decant into Toppik or Xfusion-style bottles if openings match.
• Use included tapping method if dispensing directly from the refill.
• Store in a dry place to keep fibers flowing smoothly.

How do I remove Minute Hair fibers and are they safe for my scalp?

The fibers are temporary and wash out easily with shampoo; they will not clog pores or alter natural hair growth. Formulated to be hypoallergenic, they are intended for cosmetic coverage only and should be removed regularly during washing to keep the scalp clean. If irritation occurs, discontinue use and consult a professional.

• Removes with a normal shampoo and water wash.
• Hypoallergenic formula; does not affect hair growth.
• Do not apply to wet hair; use only on dry, styled hair.
• Reapply after washing or as needed for coverage maintenance.

Who is this for: Minute Hair Hair Building Fibers 100 g in Dark Brown suits anyone seeking an affordable, high-volume refill for hair fiber applicators—men and women with thinning hair, receding hairlines, or patchy density who want immediate cosmetic improvement without medical procedures. It’s ideal for users who already own shaker-style bottles from Minute Hair or competitor brands like Toppik and Xfusion and prefer a refill that blends naturally and holds well when sealed with hairspray.
