1. Side part / gentleman's cut
89/100 fit
Best on 1A–2B · top 2–4 in (5–10 cm) · recut every 4–5 weeks
Why it ranks here
- Suits 1B straight hair: the shape holds without fighting how your hair falls.Hair physics
- The part can follow your front cowlick instead of fighting it.Barber consensus
Needs a recut every 4–5 weeks to stay sharp (about $300/yr at $30 a cut).
When it doesn’t work
- The part must follow your whorl; from hairline stage 3 it is only possible with caveats.
- 3B–4C hair (curly and coily): the shape depends on a texture it can't hold, so we rule it out.
- Low-density hair: the cut relies on bulk that thin hair doesn't have.
