Thermal Protection
Hi all, I came across this claim on a hair styling product:
Thermal Protection: up to 500°F (260°C).
Is this a “loose marketing claim” or does this claim need substantiation? If so, how? Can’t imagine a hair strand will survive this temperature for a long time regardless of the hair styling product used. -

I should have added that it is not a product specially made for blow drying

OK, I’m giggling. It’s awful, but really dark humor. Healthy hair burns at Just over 450F, (actually 233C/451.4F). I’m just imagining someone taking that claim seriously…
I know, I’m a horrible person before I’ve had enough coffee.

Perhaps they have in vivo test results

Love it.

That’s indeed really funny, didn’t realize hair starts to burn at that temperature. 🙂 Croda however promises “outstanding heat protection” up 220C with their Mirustyle, Sounds still pretty high to me…

I have done some hair straighteners but to a very basic level as it was dropped eventually for reasons we all know, nothing better than Methylene Glycol (aqueous formaldehyde solution) but regulations won’t let you go beyond 0.2% maximum. During those trials we used to have silicones in formulations to claim thermal protection but that was it. Maybe the link below further gives away something.

For sure that it will not protect from infinite high termal exposition but i wonder if it can do it temporary at least. In theory the mechanism is to avoid water evaporation and reducing heat transfer. Do they really do it?
I wonder if this last property it is true, would not be contradictory if you are precisely trying to heat it? -
@PharmaSpain good point.
