1. Diagnostic Technology — The K-Scan
Exclusive salon tool
K-Scan — AI-powered diagnostic camera
The K-Scan is a patented diagnostic camera that allows you to "see the invisible." Powered by Artificial Intelligence trained on over 12,000 images, it offers an integrated O+O (Online + Offline) experience for an ultra-personalized product prescription.
AI trained on 12,000 images 8 indicators analyzed 3 lighting technologies Scores: Low / Medium / High
The 3 lighting technologies
| Light | What it reveals |
|---|---|
| White Light | Surface, shine, general pore condition, density, diameter, dryness, dullness, sebum |
| Cross-Polarized Light | Eliminates reflections — reveals redness, inflammation, and blood circulation |
| UV Light | Detects porphyrin (bacteria as fluorescent spots) and dandruff invisible to the naked eye |
The 8 key indicators measured
| Indicator | Technical description | Light used |
|---|---|---|
| Porphyrin | Bacterial accumulations — fluorescent spots | UV |
| Dandruff | Analysis of desquamation and type of dandruff | UV / White |
| Sebum | Lipid level at the hair root | White |
| Redness | Scalp sensitivity and inflammation | Polarized |
| Density | Number of hairs per cm² — evaluation of hair mass | White |
| Diameter | Fiber thickness — detection of thinning | White |
| Dryness | Skin barrier hydration level | White |
| Dullness | Fiber's ability to reflect light | White |
Hair Loss Risk Index: The K-Scan calculates a specific index combining density (hair quantity) and diameter (fiber thickness) to detect and prevent hair thinning before it is visible to the naked eye.

3. In-salon steam treatment rituals
Why steam? Warm humidity opens pores and cuticles, improves blood circulation, promotes collagen production, purges excess sebum, and optimizes active ingredient absorption. Results: reduced breakage, dandruff control, growth stimulation.
Common reference protocol (8 steps)
- K-Scan Diagnosis — Initial "Before" evaluation.
- Double shampoo — Extended massage during the 2nd wash.
- Fiber steam — On hair only, 5 minutes.
- Targeted treatment — Application of mask or Fusio-Dose.
- Mixed steam — On scalp AND lengths, 5 to 20 minutes depending on the ritual.
- ⚠ Mandatory cooling — Allow scalp and fiber to air cool (massage or comb). Never rinse directly after steaming.
- Rinse with lukewarm water + apply heat protector.
- Final K-Scan Diagnosis — "After" proof of efficacy for the client.
Absolute rule: Complete cooling before rinsing is imperative to close the cuticle and lock nutrients into the fiber.

4. Frequently Asked Questions
Why use the K-Scan's UV light?
UV light detects porphyrin (bacterial accumulations that appear as fluorescent orange spots) and dandruff particles invisible to the naked eye under white light. This is essential for accurate anti-dandruff diagnosis.
Is the K-Scan's AI reliable?
Yes. The AI was trained on a database of over 12,000 hair images analyzed by Kérastase experts. It generates scores (Low / Medium / High) for each of the 8 indicators with maximum precision.
Should hair be rinsed immediately after steaming?
No — this is the most important precaution. After the steam phase, it is mandatory to allow the scalp and hair to cool naturally. This cooling time closes the cuticle and locks in nutrients. Rinsing with lukewarm water comes after.
Which iPads are compatible with the K-Scan?
The K-Scan app works on iOS 14 to 17 with: iPad Pro 12.9" or 11", iPad 10th generation (10.9"), iPad Air (10.9"), and iPad Mini (8.3").
How do I set up the K-Scan for the first time?
Connect the iPad to the Wi-Fi network emitted by the camera (factory password: LOREAL35 or Kscan#@839). During the first pairing, the app requires you to create a new personalized secure password for the salon.
