Hair Building Fibers

Hair building fibers are tiny colored fibers that cling to your own hair and fill in the look of thin areas. Sprinkle them on dry hair, pat them in and set with hair spray, then wash them out with shampoo.

How hair building fibers work

The fibers are electrostatically attracted to existing hair, so they blend in and add the look of density at the roots and part. They are cosmetic, and they do not change the hair itself.

Choosing a shade

Match the fibers to your hair color in natural light. If your hair has highlights or gray, pick the shade closest to the area you want to fill, and test it in a mirror before you go out.

Applying them

  • Start with clean, dry hair and style it first.
  • Shake a small amount over the thin area and pat it gently.
  • Set the look with a light hair spray, and keep them away from your eyes.

Questions about hair building fibers

Will they come off on pillows or in rain?

Fibers can transfer when wet or when brushed against fabric, so many people set them with hair spray and avoid heavy rain or sweat.
