Heads-up about oils:
When people talk about certain oils being able to withstand certain high temperatures:
1) the experts speaking on the matter are usually those within the culinary arts community and
2) they are usually referring to the smoke point --the temperature after which the oil changes in taste and consistency.

You may hear the terms "smoke point" and "heat stable" together. The term heat-stable is often mistaken for heat-absorbing in the CG community, but the two do knot mean the same thing. An oil that is heat-stable will not necessarily shield your hair from heat.

For an oil to have heat stability only means that the molecular composition (which makes the taste of the oil) has a high tolerance for heat --it does NOT mean that the oil will not get hot!

Think about how we cook: We apply heat to oils so that that heat can transfer to and FRY our food.

That being said, the oil will not get any hotter than the source of the heat. Even so, 425degrees F is not child's play, as we all know.

Keratin is NOT heat stable, so please, be careful with your heat-styling. Use your protectants when using high heats, not oils in lieu of them. Oils will not protect the hair.
