Frequently Asked Questions

buzzcutlab FAQ

What does guard number mean?

Guard numbers (#0 through #8) indicate the size of the attachment that fits on hair clippers, determining how much hair is left. A higher number means a longer cut. For example, a #1 guard leaves hair 3mm long, while a #3 guard leaves hair 10mm long.

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, requiring trimming every 1-2 weeks. The #3 guard cuts to 10mm (3/8 inch), providing a softer, more textured appearance with minimal scalp visibility and lower maintenance, needing a trim every 2-3 weeks.

Which guard size should I start with?

Start with a longer guard size (like #4 or #5) if you're new to buzz cuts, as it leaves more room for adjustment. You can always go shorter. For a more personalized starting point, use the Face Shape Analyzer tool for a recommendation tailored to your features.

How long does it take to grow from a #2 to a #4 buzz cut?

Growing from a #2 (6mm) to a #4 (13mm) requires approximately 7mm of growth. With average hair growing about 0.5mm per day, this would take roughly two weeks. Use the Hair Growth Timeline tool to visualize this exact journey with weekly checkpoints.

No, Shadow OS is not an astrology app. It does not require your birth data or provide daily horoscopes. Instead, it focuses solely on your questions, offering one clear direction based on an ancient decision-making system.

Unlike AI chatbots that often validate your thoughts, Shadow OS provides an independent answer based on the 64 hexagrams. This unique approach ensures that you receive a direction that may challenge your preconceived notions rather than simply agreeing with you.

Can I use Shadow OS for everyday decisions?

Absolutely! Shadow OS is designed for both significant life choices and everyday queries. Whether you are deciding on career moves or personal dilemmas, the app is versatile and relevant for various situations.
