If you have fine or thinning hair and want a quick, non-invasive way to improve coverage, Toppik fibers offer an easy cosmetic solution. Made from colored keratin protein, these lightweight fibers cling to individual strands to visually increase hair density without changing your hairstyle. The Medium Brown shade is matched for common natural tones and the 27.5g size is suitable for regular touch-ups and daily use.

How do Toppik fibers work to make hair look thicker?

The fibers are tiny, statically charged keratin particles that attach to existing hair shafts, creating a fuller visual texture. They blend with your natural hair so the added volume looks undetectable and natural from close range and at a distance.

• Colored keratin matches and integrates with real hair strands
• Static cling secures fibers to individual hairs for immediate coverage
• Lightweight formula avoids weighing hair down
• Works on men’s and women’s hair for spot coverage or overall density

Will the fibers stay in place through weather and activity?

Toppik fibers are designed to resist everyday elements such as wind, light rain, and perspiration, so results hold up during normal daily activities. They remain until removed by shampoo, providing temporary coverage that lasts through the day.

• Resists light rain and wind during daily wear
• Holds through moderate perspiration and activity
• Easily removed with your regular shampoo routine
• Can be layered with styling products for extra hold

How do I apply Toppik fibers for the best, most natural-looking results?

Start with dry, styled hair. Shake or spray the fibers over thinning areas, then gently pat to disperse and blend. A little goes a long way—build coverage gradually until you achieve the desired fullness.

• Style hair first to establish the natural look and direction
• Apply fibers sparingly, adding layers for more density
• Pat or brush lightly to integrate fibers with real hair
• A fixation spray can be used for additional staying power

Are these fibers safe to use with colored or treated hair?

Toppik fibers are a cosmetic product formulated from colored keratin, intended to blend with dyed and natural hair without altering color or texture. Avoid contact with eyes and follow normal care routines for treated hair.

• Works as a root touch-up between color appointments
• Doesn’t permanently change hair color or structure
• Compatible with most styling and finishing products
• Wash out completely with shampoo when desired
