Before performing chemical services, it is essential to check the hair’s condition, porosity, and previous chemical treatments. This assessment provides valuable insight into how the hair may react to the chemicals being used.

Understanding the hair's condition allows the professional to determine if it is healthy enough to undergo chemical processing or if it requires special consideration or additional treatments beforehand. Porosity indicates how well the hair can absorb moisture and chemicals, which is critical in predicting how the hair will respond to the service. Additionally, knowing about previous chemical treatments is vital, as it influences the strength of the products to be used and helps avoid potential damage or undesirable outcomes.

This focused assessment ensures not only the effectiveness of the chemical service but also the safety and health of the client’s hair, leading to better results and client satisfaction.
