Understanding the difference between “permanent hair removal” and “permanent hair reduction” is crucial for both practitioners and clients in the laser hair removal industry. The FDA definitions are especially important.
Definition: Permanent hair removal means completely eliminating hair in the treated area, with no regrowth after the full course of treatments.
FDA Stance: The FDA does not allow marketing that claims “permanent hair removal.” Most technologies reduce hair growth by about 90%, with some variability. Thus, the FDA does not acknowledge “permanent removal” without noting possible regrowth.
Definition: The FDA defines permanent hair reduction as a long-term, stable reduction in hair regrowth after treatment. This stability must last longer than the hair follicle’s growth cycle, which can be 4–12 months depending on the body part. The FDA measures reduction at 6, 9, and 12 months post-treatment.
FDA Approval: The FDA has approved certain devices for “permanent hair reduction.” To check if a specific manufacturer has FDA clearance, visit the FDA’s Medical Device Databases in the 510(k) database. Approval for the Candela GentleMax Pro Plus is here.
