In my Fry Eggs, Not Your Hair experiment I demonstrate the effects of heat transfer on an egg to emphasize the importance of incorporating a heat protection product into your thermal styling regimen. If this demonstration does not convince you that heat damage is real, I really do not know what will. Heat softens the keratin in hair to become more pliable; however, if you are not careful, too much heat penetrating the hair too fast will cause water to boil on the inside of the hair shaft, which will instantly weaken the hair.
If you are going to use heat on your hair, there is no way that you can completely eliminate the damaging effects that it will have, but you can decrease the amount of damage by protecting yourself. To read more go to NaturallyCurly.com.
