Found a stat about formaldehyde in hair straighteners that made me put down my brush
I was reading the FDA website last night after a client asked about safety and saw that some smoothing products release formaldehyde when heated above 300 degrees. I've been using a flat iron at 450 for years without thinking about it. Has anyone else switched to lower heat or different products after seeing those numbers?

Did you check what specific chemicals are in your current straightener or styling products? I looked into mine after reading similar info and found methylene glycol listed, which is basically formaldehyde in liquid form. Feels like a lot of these brands hide behind fancy names for the same stuff. Does your brand list anything that sounds like a chemical name you don't recognize?

Methylene glycol? Are you serious? I had no idea they could just rename formaldehyde like that and call it a day. I checked my bottle and sure enough, there's "methylene glycol" right there in tiny print. I always just assumed it was some harmless preservative, not the same stuff they use to embalm things. That's honestly a little terrifying

Oh gosh, I had the exact same shock when I looked closer at my own stuff... turns out my "protein smoothing spray" had methylene glycol listed third on the ingredient list. I felt so stupid for not checking sooner, honestly it's scary how common this is once you start looking. Makes you wonder what else they're slipping in there with a fancy name.
