Minute Hair Hair Building Fibers 100g Refill — Dark Brown, Static-Charged Keratin for Instant Thicker Hair

Minute Hair Hair Building Fibers (100 g, Dark Brown) are lightweight, statically charged keratin fibers designed to instantly conceal thinning areas and refill many competitor-style dispensers.

These dark brown hair fibers by Minute Hair come in a 100-gram refill size that fits most shaker-style and dispenser bottles, including those from brands like Toppik and Xfusion. The fibers cling to existing hair with static charge to create an immediate appearance of thicker, fuller hair. They are intended as a temporary cosmetic cover-up that washes out, and they work best when combined with a fiber-hold spray to resist wind and perspiration.

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

Apply to dry, styled hair starting from the back of the scalp and moving forward, following your natural hairlines. Dispense fibers sparingly, pat gently to blend, and use a light-hold spray to lock them in place. Avoid heavy contact between comb teeth and the root area immediately after application.

• Use dry hair and style beforehand for best coverage.
• Shake or invert the bottle and tap to dispense fibers onto thinning spots.
• Pat lightly to distribute fibers and create a natural finish.
• Finish with a strong-hold or fiber-hold spray to improve longevity.

Will Minute Hair fibers fit my existing Toppik or Xfusion bottle?

The 100 g refill is compatible with most aftermarket and competitor shaker-style dispensers because fibers are sold loose and can be transferred into refillable bottles. Check the opening and cap type of your dispenser to ensure a secure fit before pouring. If transfer isn't convenient, use a funnel or refill pouch to reduce spillage.

• Loose 100 g format intended for refilling shaker-style bottles.
• Works with many Toppik/Xfusion-style dispensers; verify cap size first.
• Use a small funnel for clean, easy refills.

How long do the fibers last and how do I remove them?

Minute Hair fibers are a temporary cosmetic product that remain until you wash them out. They resist light perspiration and wind when used with a strong-hold spray but can be restored by reapplying fibers if movement occurs. Removal is simple with regular shampoo and water during your next wash.

• Temporary coverage: lasts until washed out with shampoo.
• Use strong-hold or Minute Hair fiber hold spray for extra resistance.
• Reapply in areas that shift after activity or combing.

Are Minute Hair fibers safe for my scalp and hair?

Minute Hair fibers are made to be non-irritating and hypoallergenic; they do not block pores or change natural hair growth. The product is cosmetic only and should be removed with regular washing. If you have sensitive skin, test a small area first and discontinue use if irritation occurs.

• Hypoallergenic formula designed for cosmetic coverage.
• Won't clog pores or alter hair growth; washes out with shampoo.
• For sensitive skin, perform a patch test before regular use.

Who is this for? Minute Hair Hair Building Fibers 100 g (Dark Brown) suit men and women seeking an economical refill to maintain a natural-looking, fuller hairstyle between washes.
