What is the purpose of leaving the ends out of a thermal iron?

Leaving the ends out of a thermal iron primarily serves to avoid damage. When heat is applied to the ends of the hair, which are often the oldest and most fragile part of the hair strand, it can cause additional dryness and breakage. By not leaving the ends in direct contact with the heated barrel, you essentially protect them from potential heat damage.

The ends of the hair can often become brittle and weak from excessive heat exposure, leading to split ends and compromised hair health. This technique also helps in maintaining a more natural look, as the curled sections near the roots can create shape and volume without compromising the integrity of the ends.

This method not only protects the hair but may also help in creating a softer, more diffused look to the style, which can enhance the overall appearance without sacrificing hair health. Therefore, leaving the ends out of a thermal iron is an effective practice for preserving hair quality while styling.
