How often should hair be trimmed after receiving a perm or relaxer?

The recommendation to trim hair every 6 to 8 weeks after receiving a perm or relaxer is based on the need to maintain healthy hair and manage split ends. When hair undergoes chemical processes like perming or relaxing, it can become more susceptible to damage, particularly at the ends. Regular trims help prevent breakage, keep the hair looking healthy, and enhance the overall appearance of the style. This schedule allows for the maintenance of hair quality while accommodating the natural growth cycles of hair, ensuring that any damaged ends are removed before they can affect the rest of the hair. Regular trimming also helps in reshaping the hairstyle, making it easier to manage over time.
