This Hairfree Hair Growth Reduction Chart shows the average time required to achieve 99.5% hair reduction

  • Left column shows % of hair reduction after each weekly application
  • Lower column shows how many days to achieve hair reduction
  • Dark brown column represents average thickness blond to brown hair
  • Black column represents thick dense hair dark brown/black
  • Hair thickness and density affects the performance of Hairfree
  • Based on Fischer-Saller hair color and density chart
  • Results vary depending on hair thickness and density
Participants were measured each week to determine level of hair reduction. The following significant differences could be observed between Hairfree™ treated areas and placebo treated areas of skin. An overall decrease in hair density on areas treated with Hairfree™ of +/- 25% every week was measured using a Cross-Section Trichometer over one square centimeter of skin x 100 (mm2/cm2 x 100). Participants also noted a reduction in hair thickness during the trial. At the conclusion of the study an overall decrease in hair density on Hairfree™ treated areas was +/- 93% measured using a Cross-Section Trichometer. Hairfree™ has been shown to be a safe and effective method for progressively stopping hair root growth.

Results vary depending on hair thickness and density. Coarse black hair will take longer to treat than thin blond hair.
