During a haircut, what is the best way to prevent split ends?

Regular trims are vital in preventing split ends because they help remove damaged or dry ends of the hair, which can lead to further splitting if left unattended. By getting trims every six to eight weeks, you maintain the overall health and appearance of your hair, allowing it to grow healthier from the roots down. This practice not only eliminates the split ends that have already formed but also acts as a preventive measure against future splitting by reducing the chances of hair being caught on clothing or snagged during styling.

The other options may not effectively address the causes of split ends. While using more hair products might condition the hair temporarily, it can also lead to product buildup, which may weaken hair in the long run. Avoiding hair washing can actually lead to a buildup of oils and dirt, leading to other hair issues. Limiting styling tools is beneficial for hair health, but if you don't address split ends with regular trims, the existing damage will persist and possibly worsen over time. Thus, regular trims remain the most straightforward and effective method for maintaining healthy hair and preventing split ends.
