TOPPIK Hair Building Fibers — Medium Brown 55g Refill, Instant Thicker Natural-Looking Volume

These lightweight, colored keratin fibers attach to individual hair shafts to conceal scalp visibility and create immediate density without dyes or harsh chemicals. Packaged as a 55g refill size, this Medium Brown shade is one of nine options designed to match a wide range of natural tones for both men and women. The formula resists ordinary wind, light rain, and perspiration and remains until removed by shampoo, giving you a non-permanent, natural-looking enhancement between washes or salon visits.

How do Toppik fibers create a fuller appearance so quickly?

The fibers use static attraction to cling to real hair, increasing hair diameter and reducing the contrast between hair and scalp. Because they are made from colored keratin protein, they mimic the texture and sheen of natural hair for an undetectable finish.

• Instant adherence to existing strands for immediate volume.
• Colored keratin matches hair for a natural texture and look.
• Minimal styling needed: apply to dry hair and pat to set.

Will these fibers stay on through daily activities?

Toppik fibers are formulated to withstand everyday conditions like light wind, perspiration, and brief exposure to rain, maintaining coverage until you wash them out. They are not a permanent treatment and are designed to be removed with normal shampooing.

• Resists light wind and moisture for everyday wear.
• Holds until washed; no bonding agents required.
• Works with standard hair care routines—shampoo removes fibers.

How should I apply Medium Brown fibers for the most natural effect?

Apply to dry, styled hair in thinning areas using a shaker or applicator, then lightly tap or pat to blend. For better precision, use a spray-lock or fiber applicator to target sparse spots and finish with a gentle pat to disperse evenly.

• Style hair first; apply fibers to dry hair for best adhesion.
• Tap or pat after application to integrate fibers with hair strands.
• Use a fiber sprayer for concentrated coverage on small areas.

Are these safe and suitable for color-treated hair?

Toppik fibers are a topical cosmetic made from colored keratin and can be used over color-treated hair to disguise regrowth or thinning without affecting hair dye. Avoid contact with eyes and follow standard safety practices during use.

• Non-invasive cosmetic solution that sits on hair surface only.
• Compatible with most color-treated hair; avoids chemical processing.
• Wash out with shampoo—no lasting alteration to hair color.
