The Cap+ Volumizing Keratin Brush is a revolutionary tool for natural-looking hair building fiber application in seconds. An unbelievable way to temporarily conceal areas where hair is thinning, the Cap+ Volumizing Keratin Brush makes it easy for anyone to use hair building fibers as part of their everyday routine for instant hair density. Dispense and brush in exactly where you want to thicken hair fullness, with no mess or accidental spills. No more changing hairstyles to conceal thinning. Feel confident every day with Cap+ by Capillus hair building fibers – makeup for hair providing instant hair volume.

How it works

How it works

With the Cap+ Volumizing Keratin Brush, thousands of miniature keratin fiber particles cling statically to your hair, instantly concealing areas of thinning. You can easily brush in just the amount of coverage that you need, focusing on sparser areas that are expertly concealed. No need to use messy sprays or wet solutions. Dry keratin fibers cling statically to your hair and wash off your hair with shampoo.

From the makers of Capillus laser therapy caps for hair regrowth, the Cap+ brush is a cosmetic tool that combs fiber particles through your hair to conceal thinning. Both product lines (Cap+ hair building fibers and Capillus caps) complement each other… one to disguise thinning cosmetically and the other to treat the hair follicle for hair regrowth medically.

Choose from 11 hair building fiber cartridge colors for the perfect match on application to your hair: Black, Dark Brown, Brown, Light Brown, Auburn, Dark Blonde, Medium Blonde, Ash Blonde, Dark Grey, Grey, Light Grey.

Each cartridge comes pre-filled with .25 oz. of volume-building fibers, the perfect amount to provide coverage for a week’s worth of use* while keeping the fibers fresh and dry for ease of application. * Will vary depending on usage.

For an easy look of fuller hair in seconds, follow these steps:

  • Before use, install batteries by sliding open the blue battery-cover plate on brush handle and install (2) AAA batteries (included). Replace battery-cover plate before operating brush.
  • For first-time use, remove cartridge seal, and align and insert cartridge into top of brush.
  • Holding brush handle face up, move power switch to the first left position to open brush dispenser doors.
  • Begin to brush hair, and push switch to the second position to dispense fiber. Release switch to stop. When satisfied with coverage, power off brush to close dispenser doors.

Usage Tips:

  • Always apply to dry, clean hair. Applying to dry hair will ensure fibers can cling to hair. Will not work on wet hair.
  • Prior to dispensing the keratin fibers, brush hair energetically for 5-10 strokes to electrostatically charge the hair.
  • Fiber dispensing:
    • Keep the brush horizontal to the floor.
    • Start from the back of head and slowly and progressively move forward towards the frontal line hairline.
    • Discontinue dispensing fibers. Less is more.
    • Style normally, avoiding over-stroking, especially for very fine or thin hair.
    • Add additional fibers if needed while brushing.
