What is the effect of using too much heat on hair styling tools?

Using too much heat on hair styling tools can lead to potential damage to hair and a loss of moisture. Hair is made up of proteins and has a specific moisture balance that is vital for its health and appearance. When excessive heat is applied, it can break down the protein structure of the hair strands, causing them to become brittle and leading to issues such as split ends, breakage, and overall dullness. Additionally, high temperatures can strip the hair of its natural moisture, making it dry and prone to frizz. Maintaining an appropriate temperature while styling is crucial for preserving the hair's integrity and keeping it healthy.
