 To relate our hair status with the physical-thermic processes that we usually submit it: (straightening, ironing, perms, hair dying, etc). |

| Understanding the different results of the hair coloration connected with the sebaceous level and the hair changes during the sexual maturation. |
| Differentiating the needs of the root or scalp from those of the hair fiber or stem. |
| Adapting the haircut (do not use razor for weak hair). |
| Interpreting the increase of the hygroscopy as a reason for the unwished frizzy hair. |
| Effective election of the washing product (shampoo or soap) and products for restoring treatments. |
