#2 vs #3 buzz cut — which suits a round face?
#3 (10mm) usually softens a round face better than #2. The site offers a face-shape fit tool for personalized recommendations.
How long to grow from #2 to #4?
It typically takes 4–6 weeks depending on growth rate, and the site's grow-out timeline shows week-by-week looks.
Is a buzz cut good for thinning hair?
Yes, shorter guards (#1–#2) can reduce contrast when paired with even lighting and gentle clipper passes.
