Tonight I washed and towel dried my hair. (Micro fiber towel, of course. I've been using those for years before I'd ever heard them being recommended for curlies.) Once it was towel dry, I used one of my recent product junkie purchases, Neutral Protein Filler (NPF) (from Sally's) on my hair. I worked it through my hair roots to ends, and left it on per the instructions.
Only to discover, a few minutes later, that NPF gives me a mild asthma attack. So, whether it works well or not, I won't be repurchasing :) I'm willing to do a lot of things for curls, but regular asthma attacks is not on the list :)
