Search “AI hairstyle” in the App Store and you’ll find dozens of apps with near-identical screenshots and wildly different realities behind them. Some produce salon-grade previews; some are novelty face filters wearing an AI costume; some are subscription traps with a hair theme. Having built one ourselves (Crinis), here’s an honest checklist for evaluating any of them — including ours.
1. Does it change the hair, or your whole face?
This is the single biggest quality divider. There are two technical approaches:
- Dedicated hair-transformation models regenerate only the hair region of your photo. Your face, skin tone, expression, and background stay pixel-identical. The result answers the actual question: me, with that hair.
- General image-generation filters re-render the entire image in a flattering style. The output is pretty — and subtly not you. Smoother skin, adjusted jaw, different eyes. You end up evaluating a hairstyle on an improved stranger, which defeats the purpose entirely.
The test: run one photo through the app, then compare the before/after with your finger over the hair. If the face changed, the previews can’t be trusted for real decisions.
2. Does the style range cover your hair?
Many apps have 100+ styles that are really one demographic’s styles in 100 variations. Check the catalog for:
- Textured and natural styles — afros, natural curl patterns, not just straight-hair cuts.
- Protective styles — box braids, locs, cornrows. Their absence is a red flag for how seriously the catalog was built. (Why previewing matters most for braids: the cost math.)
- Men’s styles — actual fades, buzz cuts, and quiffs, not an afterthought tab.
- Color as a first-class feature — since color previews are half the value of try-on.
3. What happens to your photos?
You’re uploading your face to someone’s server; the privacy policy is not optional reading. Green flags:
- Photos processed for generation and not stored on the server afterward
- No account required — apps that demand email + name + login before one try-on are building a marketing database
- No sale or sharing of image data, stated plainly
Crinis’s answers, for the record: photos are never stored, no account exists to create, and saved looks live only on your phone.
4. Is the pricing honest?
Paid apps are normal here — inference on real AI models costs actual money. What matters is whether the price is clear before you subscribe:
- The price is on the plan, not buried in a trial. A “3-day trial” that starts billing at $8–10/week is a common trap. Read the weekly price before you continue.
- One-time packs exist if you only want a few looks and don’t want a subscription.
- Weekly-only pricing with the yearly price hidden is a churn-and-burn signal.
Crinis shows the price before you buy: one-time packs of 1, 2, or 4 looks, or Crinis Pro for unlimited try-ons. Looks never expire. Weekly has no free trial.
5. Can you actually use the result?
The end goal isn’t the app — it’s walking into a salon with a target. Check for the workflow features: a before/after comparison (essential for honest judgment), saving looks to revisit after your first excitement fades, and clean export/sharing so the preview can reach your stylist’s phone. An app that generates beautifully but exports a watermarked postage stamp misses the point.
The quick test protocol
Trying any AI hairstyle app (again, including ours)? Do this in your first five minutes:
- Generate one style you know well — your current hairstyle. It should come back looking like a normal photo of you.
- Cover the hair, check the face. Identical? Good.
- Read the photo-storage line of the privacy policy.
- Find the real price after any trial.
If an app passes all four, it’s a legitimate decision tool. Crinis was built to pass them — 69+ styles across every hair type, no account, photos never stored.
