|---|---|
| Iris Root Extract (Rhizome de l'Iris) | Known for its ability to provide antioxidant protection and prolong nourishment, helping to counteract the reappearance of dry hair. |

💰 Is It Worth It? – Value & Cost Efficiency
| Aspect | Positive | Negative |
|---|---|---|
| Longevity of Results | Users often report that the softness and manageability last well into the next day, reducing the need for extensive morning styling. | Some users with very damaged hair felt the effects were temporary and required continuous daily application for noticeable change. |
| Amount Needed Per Use | The serum is generally perceived as concentrated, requiring only a small amount per application, which makes a single bottle last longer. | A few users felt that the initial investment for the bottle size was high, despite its concentration. |
| Overall Perception of Value | Many consider it a worthwhile investment for its effectiveness in transforming dry hair, viewing it as a salon-quality treatment at home. | For those with only minor dryness, the product's benefits might not justify the cost compared to less intensive conditioners. |
