Question: 1 / 400

Why should you avoid using a hot tool on wet hair?

It can cause damage and hair breakage

Using a hot tool on wet hair can lead to significant damage and breakage because water in the hair creates steam when exposed to high temperatures. This steam can cause the hair cuticle, which is the outer layer of the hair, to swell and lift, which compromises the hair’s structural integrity. The high heat combined with moisture can lead to a situation known as "hydrothermal damage," resulting in frizz, split ends, and overall weakened hair.

In contrast, using heat on dry hair allows the cuticle to remain intact, which helps to protect the hair shaft and maintain its strength and health. Therefore, for optimal hair care, it’s crucial to ensure that hair is completely dry before applying hot styling tools.
