I started using WEN towards the end of January, the 480ml Cucumber Aloe one lasted about 8 weeks. I've got short hair, fine but lots of it and greasy at the roots (grown out crop now similar to Jackie Kabler's style) and have never used as many pumps as recommended. I tend to use 2 pumps, rinse then 3 pumps. I don't reapply any as a leave in conditioner. I still need to wash daily with WEN because of my greasy roots, will leave it one day without washing at the weekend if I'm not going anywhere. No wow factor results from WEN for me, but when it ran out end March and I went back to a few days of Liz earle shampoo and conditioner it prompted me to reorder WEN. When my hair was a layered crop my hair was in good condition, as it only ever needed a quick blast with a hairdryer. Having grown it to one length albeit still short, if I don't use WEN it tangles the instant I shampoo it. For me the advantage with WEN is the tangle free aspect. I suspect, however, that WEN is contributing to drying my hair out. I can't say WEN is solely to blame, as since starting with WEN end January my hair has been coloured, grown a bit, and consequently now gets blow dried all the time. Nonetheless, my hair is dull and drier looking than it's ever been in my life with split ends. If the price of the latest TSV is good I'll likely buy it because of the tangle free aspect, and see how my hair is after it's next cut to judge whether WEN's been having an impact on the condition.
