Quality Control

An ISO 9001:2015 system, twenty-plus checkpoints and a rule we never bend: every single brush is inspected.

Quality inspection at LyDia factory
OUR QUALITY PROMISE

Inspected Piece by Piece — Not Sampled

Many factories inspect a sample of each batch. We check every single brush, because one shedding brush in a customer unboxing video costs more than an hour of inspection.

  • ✓Incoming materials — hair, ferrules and handles checked on arrival
  • ✓In-line checks at every one of the 20+ processes
  • ✓Final 100% inspection — shedding, pull test, symmetry, finish
  • ✓Pre-shipment re-check against your confirmed golden sample
