What Hairstyle Suits My Face? AI Previews 30 Seconds Before You Commit
How often does hair go wrong?
Every couple of weeks someone in your circle posts a “before vs after” disaster. The math is brutal:
- Dye: $50-300 / ₩100k-300k. If it fails, wait 3-6 months for it to grow out — or pay again to fix it.
- Perm: $100-400. If it fails, wait for hair to grow + cut.
- Bangs: free, but suffer for 2-3 months.
On Reddit r/coloranalysis (258K subscribers), 16-20% of top monthly posts are “Should I get bangs?”, “This hair color on me?”, “Bob or lob?” — the irreversibility makes it the perfect AI use case.
Quick reference: 6 face shapes × recommended cuts
1. Round (颧骨柔和)
Width ≈ length, soft jaw
| Best | Normal | Avoid |
|---|---|---|
| Collarbone-length straight | Mid-length curls | Blunt bangs |
| Side-part long curls | Light wave at collarbone | Round short cut |
| Hime-cut (公主切) | Even shoulder-length |
Goal: lengthen visually, avoid horizontal cuts.
2. Oblong / Long
| Best | Normal | Avoid |
|---|---|---|
| Blunt bangs | Side-part long | Center-part poker straight |
| Light-wave collarbone | ”8-character” bangs | High ponytail |
| Egg-roll perm | Slicked-back |
Goal: widen horizontally, shorten visual length.
3. Square
| Best | Normal | Avoid |
|---|---|---|
| 8-character bangs | Collarbone-length curls | Blunt bangs |
| Curved side-part | Mid-length straight | Pixie with sharp angle |
| Big waves | Bowl cut |
Goal: soften jawline, avoid sharpness.
4. Oval
| Best | Normal | Avoid |
|---|---|---|
| Almost everything | — | Few extreme styles |
Lucky you. Experiment freely.
5. Heart / Inverted Triangle
| Best | Normal | Avoid |
|---|---|---|
| Collarbone straight | Side-part long | Pixie |
| 8-character bangs | Mid-length curls | High ponytail |
| Hime-cut | Slicked back |
Goal: add jaw volume, avoid emphasizing forehead.
6. Diamond
| Best | Normal | Avoid |
|---|---|---|
| Center-part long curls | Collarbone straight | Blunt bangs |
| Side-part collarbone | Big waves | High ponytail |
Goal: soften cheekbones, balance narrow top + bottom + wide middle.
Face shape is just step 1
Hairstyle adaptation also depends on:
- Density: thin → don’t go too short (head shrinks); thick → don’t go too long (heavy)
- Texture: natural curl → don’t fight it with straightening (rebounds in a week); fine soft → don’t perm (won’t hold)
- Neck length: short → avoid mid-shoulder (cluttered); long → avoid super-short (exposes neck)
- Vibe: soft → straight wins; sharp → short / asymmetric
Plus dye color depends on color season (Warm Spring → honey blonde; Cool Winter → pure black or chocolate). 6+ variables — impossible to mentally simulate.
