The KEMEI hair trimmer is designed for precise hair cutting and detailing.
Powering On/Off

Trimming Techniques
The trimmer's R-shaped blade design ensures skin safety during use, making it suitable for various styles including oil head, inch head, engraving, and gradient haircuts.
- For general trimming, attach the appropriate guide comb and move the trimmer against the direction of hair growth.
- For detailing and outlining, remove the guide comb and use the bare blade. The precise sharp T-shaped carbon steel cutter head is ideal for extremely close cutting.
- Always ensure the blade is clean and oiled for optimal performance and to prevent pulling or snagging.
