What is important to assess before applying chemical treatments to hair?

Assessing hair health and previous chemical exposure is crucial before applying any chemical treatments. This evaluation allows the barber or stylist to understand the condition of the hair, including factors such as porosity, elasticity, and strength. Analyzing previous chemical exposure helps in identifying any potential damage or adverse reactions the hair may have had in the past, allowing for better decisions about which chemicals can be safely applied.

Taking into account hair health can prevent over-processing, breakage, and ensure that the treatment will deliver the desired outcomes while maintaining the integrity of the hair. This assessment is fundamental in customizing services to each client's unique hair characteristics and history. Failing to consider these aspects may lead to unsatisfactory results or damage to the hair.
