Okay, so I broke down and bought the Wen shampoo. My hair was really damaged and struggling. I have fine hair and I have a lot of it. I was having issues with dryness, breakage, and just over all yuckiness.
I'm in week 3 of using this stuff. I've been able to get back down to 2x/week cleanings already. The biggest differences I've seen is that I'm having barely any breakage in the morning, almost no frizz, and I can comb it without shuddering at the knots and dryness. Also, there is volume, so much volume. I've even been able to go back to doing my curls and they are pretty damn va-va-voom now, instead of just looking frizzy.
It does take a chunk of time in the shower. And I can tell if I don't leave in on long enough because my hair feels a bit heavy. I did the leave-in portion a few times, but you have to be careful. It's never felt greasy, but it was pretty obvious the time I used too much of it.
Overall, I'm really happy with how my hair looks and feels. Even DH noticed it. And I don't really use all that much, 6 pumps at a time. I'm hoping to make a bottle last about 2 months, which realistically makes it only about $5/month more expensive than what I was using anyway. 2 thumbs up so far.
