During a curl reformation service, which factor is crucial to determine the effectiveness of the treatment?

The effectiveness of a curl reformation treatment is significantly influenced by hair texture. Hair texture refers to the individual characteristics of the hair strands, including their thickness, porosity, and overall condition. Different hair textures will respond variably to chemical treatments, such as relaxers or perm solutions. For instance, coarse hair may require a different formulation or processing time compared to fine hair in order to achieve the desired results without causing damage.

Understanding the hair texture helps the stylist to select the appropriate technique, chemical strength, and processing time that will yield the best outcomes for the client's specific hair type. On the other hand, while factors like client preference, humidity level, and type of perm solution are relevant in the overall process, they do not directly impact how effectively the treatment will reform curls based on the way the hair structure interactions with chemical agents. Therefore, assessing hair texture is paramount for achieving successful results during a curl reformation service.
