Frequently Asked Questions
buzzcutlab FAQ
What does the guard number mean?
Guard numbers (#0 through #8) correspond to the plastic attachments that fit on hair clippers to control cutting length. The number indicates the size of the guard, with higher numbers leaving more hair. For example, a #1 guard typically cuts hair to 3mm, while a #4 guard leaves 13mm of length.
What's the difference between a #2 and a #3 guard?
The #2 guard cuts hair to 6mm (1/4 inch), offering a clean, sharp look with low scalp visibility. The #3 guard cuts to 10mm (3/8 inch), providing a slightly longer, softer appearance with minimal scalp visibility and requiring less frequent maintenance, typically every 2-3 weeks instead of 1-2.
Which guard size should I start with?
A good starting point for a first buzz cut is often a #3 or #4 guard, as these lengths are forgiving and allow you to adjust shorter later. For a more personalized recommendation, use the Face Shape Analyzer tool, which suggests suitable guard sizes based on your individual facial features.
How often should I trim my buzz cut?
Maintenance frequency depends on your chosen guard size and how neat you want to keep it. Shorter cuts (like #0 to #2) typically need a trim every 1-2 weeks to maintain a crisp look. Longer buzz cuts (like #3 to #5) can last 2-3 weeks between trims. The Length Converter tool provides specific guidance for each guard.
