Chaz Dean's Wen range has a trio of hair volumizing products that are best sellers on QVC. I think that it is brilliant that a guy who has pioneered the green movement, launched a shampoo-free shampoo and who has pledged to change the world one head at a time should capture the hearts of TV shoppers. Chaz's Wen Lavender conditioner, styling cream and volumizing spray are very good products. However, at the risk of splitting hairs with such a nice chap, I'd have to say that they could be greener. But I'll come back to that.

First, here are some of the good things that Wen achieves. Lavender Cleansing Conditioner ($26) is big on organic aloe, which will sooth the most irritated scalps as well as being an important anti-inflammatory. Of the handful of botanicals, there is rosemary, a great natural hair conditioner that gives body and lustre to dry hair. But what I really like is the petal power of marigolds, which contain something called luteins, a potentially indispensible source of skin protection. According to a Harvard research team, it may have the potential to act as a preventative agent against UVB-induced skin cancer and skin damage.

The Lavender Volumizing Treatment Spray ($32) has some of the heavy hitting ingredients that you would expect to find in a facial serum. There is marine collagen and a great peptide, palmitoyl pentapeptide-3 (which is our friend Matrixyl). There some powerful botanical antioxidants in the form of white tea, goji berry, with loads of vitamin C, and acai, rich in fatty acids.

I am afraid that in my book Chaz loses a few points for a fairly heavy handed use of silicones. Making, for example, the Styling Creme Water a fairly mediocre product. But the real let down comes from the number of irritants ,including: ethylhexylglycerin, methylisothiazolinone and aminomethyl propanol, which is restricted to concentrations of up to 7%, phenoxyethanol, an irritant that can also damage the central nervous system, and iodopropynyl butylcarbamate, which a Danish study found to be a toxin. DMDM hydantoin, which can contain small amounts of formaldehyde.
