How does a curling iron damage your hair?

Protein denaturation caused by high temperature

When a curling iron’s temperature exceeds 300°F, the hair’s keratin structure begins to irreversibly denature. This temperature is the default setting for most ceramic curling irons in the United States and is particularly common for people with coarse hair.

Water loss and lipid layer disruption

Each use of a curling iron reduces the hair’s moisture content by 15-20%, while also damaging the protective lipid layer. This is why many American women find their hair becomes dry and frizzy after long-term use of curling irons.

Mechanical injury

In my salon in Los Angeles, I see too many clients whose hair breaks due to incorrect use of curling irons. Improper wrapping and excessive tension can cause mechanical damage to the cuticle layer of the hair.
