What is a crucial step when performing a chemical straightening treatment?

Assessing the condition of the hair before application is essential in a chemical straightening treatment because it allows the stylist to determine the health and integrity of the hair. This step helps identify any existing damage or weaknesses and informs the stylist about the most suitable treatment approach. Different hair types and conditions may respond differently to chemical processes, so a thorough assessment ensures that the correct product and technique are chosen to minimize the risk of further damage and to achieve the desired results.

By evaluating factors such as porosity, elasticity, and texture, the stylist can make informed decisions regarding the strength of the product used, the processing time, and any necessary preparatory treatments that may enhance the overall outcome. This level of care and consideration is necessary for achieving optimum results while maintaining hair health.
