Minute Hair Hair Building Fibers Refill 100g (Medium Brown) — Natural-Looking Thickening, Sweat-Resistant

Minute Hair Hair Building Fibers (100 g, Medium Brown) are ultra-fine, statically charged keratin fibers that instantly thicken and conceal thinning areas for a natural-looking fuller head of hair.

If you want fast, non-permanent coverage for sparse patches or a receding hairline without altering your natural hair, this 100-gram refill gives you salon-quality blending that works with bottles from other brands. Designed to mimic the look and texture of real hair, these fibers cling to existing strands and provide immediate visual density. They’re sweat- and wind-resistant when sealed with a strong hairspray and rinse out easily with shampoo.

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

Start with dry, styled hair and work from the back toward the front following your hairline. Dispense fibers by shaking or inverting the bottle and tapping its side so the fibers fall where you need coverage; then gently pat to blend. Avoid brushing too close to roots after application to prevent disturbing the fibers.

• Apply to dry hair only, starting from the back to the front.
• Tap bottle or shake lightly to control fiber placement.
• Pat lightly to disperse fibers and blend with your natural hair.
• Lock fibers with a strong hairspray—Minute Hair fiber hold spray is recommended.

Will these fibers work with my existing fiber bottle from other brands?

Yes—this 100 g refill is formulated to be compatible with most commercial dispensing bottles, including popular options like Toppik and Xfusion. The fiber size and static charge are engineered to adhere to natural hair, so you can refill your current applicator without changing technique. Using a compatible bottle keeps application precise and minimizes waste.

• Compatible with many third-party shaker bottles and applicators.
• Same fiber texture and electrostatic properties for consistent coverage.
• Easy refill format saves money versus buying a new bottle each time.

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

Minute Hair fibers provide temporary coverage that remains until you shampoo them out. For everyday activities they resist normal perspiration and light wind, but for strong hold in active conditions use a quality finishing spray. Removal is simple—regular shampooing and rinsing fully remove the fibers without affecting your scalp or natural hair growth.

• Lasts until washed out with shampoo.
• Perspiration and wind resistant when sealed with hairspray.
• Gently removed through normal washing—no residue or pore-clogging.

Are Minute Hair fibers safe for sensitive skin and daily use?

The fibers are made to be hypoallergenic and non-comedogenic, so they won’t clog pores or interfere with hair growth. They’re intended for cosmetic use only and don’t deliver any medical treatment. If you have known sensitivities, test a small area first and discontinue if irritation occurs.

• Hypoallergenic formulation suitable for most users.
• Cosmetic product—does not affect hair growth or scalp health.
• Recommended to patch-test if you have very sensitive skin.
