For those of you who know and love Living Proof's No Frizz hair treatments, you'll be excited to hear the company has just brought out a shampoo and conditioner ($24 each). At first glance, they both seemed so full of unpronounceable chemicals that I thought I was going to have to rain on the Living Proof lovers' parade. However, while there isn't anything that hasn't been concocted in a lab (there is barely a whiff of botanicals here), most of the ingredients (with a few notable exceptions - see below) are fairly benign.

Both the conditioner and shampoo major on PolyfluoroEster, the anti-frizz secret sauce that was supposedly brought to us by MIT scientists. Many of the other ingredients are newish variants on standard drug store shampoo fare that seem to have been chosen for being less irritating than those typically found.  Sodium lauroyl methyl isethionate seems to be benign and gentle and PEG-150 pentaerythrityl tetrastearate, a thickener that is a less irritating substitute for diethanolamide (DEA). Ditto for PEG-6 Caprylic/Capric Glyceride, which goes by the name of Softigen 767 and seems be non-irritating.

On the whole, the shampoo isn't too bad at all. Not surprisingly, the worst things are in the preservative department.Tetrasodium EDTA is a marine pollutant, methylchloroisothiazolinone and methylisothiazolinone are irritants, as is butylphenyl methylpropional. The conditioner, however, loses points for behentrimonium chloride, a toxic compound that can damage the eyes at very low concentrations.
