When is it appropriate to perform a relaxer retouch?

A relaxer retouch is specifically performed when there is new growth that needs to be treated, which is typically about 1 inch or more of new hair that has not undergone the relaxing process. This measurement is important because the new growth often has a different texture than the previously relaxed hair, and applying the relaxer at this point ensures that all hair is uniformly straightened.

Performing a retouch allows the stylist to maintain consistent results and prevent visible demarcation lines where the relaxed hair meets the new growth. This practice helps in achieving a smooth and cohesive appearance throughout the hair, ensuring that the relaxed hair and new growth blend seamlessly.

While the state of the hair being wet can be relevant in other contexts, it's not a determining factor for when to do a retouch. Additionally, simply requesting a new hairstyle does not warrant a relaxer retouch if there is not significant new growth. Faded color, though important in certain treatments, does not relate to the need for a relaxer retouch specifically.
