What is the effect of using a hot tool on wet hair?

Using a hot tool on wet hair can indeed cause severe damage. Wet hair is in a more fragile state than dry hair due to its increased elasticity and the presence of water, which expands the hair shaft. When heat is applied to hair that is still wet, the moisture trapped inside the hair can rapidly turn into steam, which can lead to a number of negative effects.

This includes causing the hair to bubble, which can create weak spots, split ends, or even lead to breakage. The high temperature can destroy the protein structure of the hair, leading to irreversible damage and a generally unhealthy appearance. Practicing caution and ensuring hair is fully dry before using hot tools is essential for maintaining hair health.

The other options don’t accurately reflect the reality of using heat on wet hair. While it may seem that heat would enhance styles or curls, doing so on wet hair can prevent effective styling and yield poor results.
