However, it's important to note that:
* This is a general guideline. The exact temperature at which hair burns can vary depending on factors like hair type, thickness, and moisture content.
* Hair damage can occur at lower temperatures. While burning is a visible sign of extreme damage, heat styling tools like flat irons and curling irons can cause damage to hair structure even at temperatures below 450°F.
It's best to use heat styling tools at the lowest temperature possible to achieve your desired style and always apply heat protectant products to minimize damage.
