The date code is an alphanumeric code that is unique to that product. Here’s where to look for it:
- For a styler, it’s located between the plates, opposite the on/off switch.
- For the Duet, you’ll find it on the underside of the styler, near the filter.
- On hairdryers, it’s on the body of the dryer.
- For hot brushes and curlers, check the underside of the handle.
- You can also find this on the label close to the plug.
