Others are vaporized in different molecular forms — for instance, silicon monoxide, silicon dioxide and iron monoxide.[/FONT][/FONT][/FONT][/font]
This gives me an idea... the next time I get a bunch of breakage I should turn the iron up to max and see what happens...
1000 degrees??Where did you read that?? I know that certain silicones can handle that type of heat before the bonds break, making them superb heat protection, but I don't think product-free hair can stand that
...
Are you referring to the thread Navsegda posted?
what does that equal in farenheit? i guess i could google it but i feel lazy
Lmao...Yes, I am reffering to Navsegda's post! Maybe I am a tad off.
so let me see if I can expound on the topic...
That makes so much sense. Thanks for posting, I printed this out
It's ok. I studied under the tutelage of the Great Navs
Um, generally speaking anything above 450 on a flat iron would cause damage (even with the heat protection). But the thing to keep in mind is that just b/c the iron is turned up to 420 degrees doesn't mean you can just run the flat iron through the hair all willy nilly. The heat doesn't immediately leave the hair once it's come in contact with the strand; the temp builds up. Like when you add cold veggies to a pot of boiling water...the water doesn't immediately go back to room temperature. It's still hot and actually not too far from the boiling point. So if you take 2 or more passes of an iron at 400 degrees that's double the heat setting...which means that heat damage is EASY to do. It's pretty safe to say that 350 degrees and lower is ok for the hair (provided you make 1-2 passes with the iron). If that doesn't work, review your prep for the hair prior to the flat iron (like how you dried the hair, what products you have on there, etc).

for the evening. 
No prob, you guys. Also keep in mind that even if you add more than one heat protectant, you are helping to prevent damage, but that still doesn't mean that you should turn the heat up either. The protection of the different silicones do add compounded protection, but why compound the heat to test out the strength of those products?!
Another thing I wanted to bring up: Actual heat damage actually occurs due to the temperature. Go to PG.com and you can see pics of hair strands that have bubbles in the strands that exploded b/c the moisture boiled over inside the strand. If you don't have the appliance at an excessive temperature, the hair won't get damaged (especially if using a heat protectant, b/c the heat is buffered by the bonds of the silicone compounds).

Do you know where she got her information?? I've searched for a link that could explain this for a very long time, and I still was unable to find one. I would like to understand the science, too.
I do the same thing, but my background is in psychology (don't worry I'm not "analyzing" all of you 
lol!)Essentially, from chemistry and physics textbooks. Navs has a degree in neuroscience. Once you understand the fundamentals of biology/chemistry/physics, and work with it on a regular basis, it's kind of difficult to not apply your studies to everyday life and look at everything through those kind of eyes. Like looking at the "grid of the Matrix"
I'll check the web and see what sites I can find for you though. Give me a bit and I'll come back to this thread
ETA: Here's one site I always find interesting...http://www.hair-science.com/_int/_en/index.aspx
