Define & Defend Duo

This product is specifically designed for short hair (such as pixie cuts and bobs), bangs, and edge flyaways. Since the plate is only 0.65 inches wide, it is less efficient for long or thick hair. For users with long hair, we recommend using it only for adding root volume or styling small detail sections.

No, this is not a defect. The sound comes from the built-in fan motor while it is operating. The air outlet continuously blows air to help set the hair the moment it leaves the heated plates, locking in the curl and preventing the hair from overheating.

We use a heat-insulated tip design, so it is safe to hold during normal use. Since the body is slim, beginners are advised to wear the heat-resistant glove included with the product until they are familiar with the styling process, to avoid accidentally touching the heated plate area with their fingers.

No. To protect the health of your hair and achieve the best styling results, please make sure your hair is 100% dry before use.

This product has 5 temperature settings. For fine, soft, or damaged hair, we recommend 280°F–320°F. For normal hair, 360°F is recommended. For coarse or thick hair, 390°F–430°F is recommended. It is best to start with the lowest temperature and adjust as needed.

Yes, it supports 100V–240V dual voltage. Its compact and lightweight design makes it ideal for travel worldwide. No voltage converter is needed—only a plug adapter may be required.

Absolutely. The slim 0.65-inch plates can get very close to the roots and short beard hair, making it an ideal tool for creating slicked-back or side-parted hairstyles, as well as taming and smoothing messy facial hair.
