Why is it important to check the hair before and after shampooing prior to cutting?

Checking the hair before and after shampooing is crucial for assessing its condition, texture, and any damage, which informs the cutting technique to be used. It allows the stylist to determine how the hair behaves when wet versus dry, influencing the final style and ensuring a more accurate cut. Additionally, this practice helps identify any underlying issues, such as split ends or excessive dryness, that need to be addressed during the haircut. Overall, it enhances the overall quality and precision of the haircut.
