Flat ironing very wet hair is not recommended because moisture in the hair can cause damage when exposed to high heat. When hair is wet, the water inside the hair shaft turns to steam, and this steam can cause the hair to expand and potentially lead to breakage or frizz. High heat applied to wet hair can also lead to what is called "steam damage," which compromises the hair's structure and can result in long-term damage.

In contrast, using heat protectant spray helps to safeguard the hair against potential heat damage during styling. Properly sectioning the hair ensures that the iron can effectively straighten every section without applying excessive heat, which leads to better results and reduced risk of damage. Additionally, using the correct temperature for the specific hair type is crucial because different hair types have varying heat tolerance levels. Adhering to these best practices promotes healthier hair and helps achieve desired styling outcomes without causing harm.
