Wen is a patented hair line, so nothing will be just like it.
I've been using it since earlier this year and I love it. I'd continue to use it if I could afford it. My hair is super curly and coarse and probably tangles much more than yours. I haven't found a product that can eliminate the tangles but it does make my hair easier to manage. After consistent use I've noticed my naturally dry hair type begins to retain moisture better. I don't really use it to condition or deep conditioner because I want to save product, so I only use it to wash (but I have used it to dc and cond.).
At first I didn't really think it was doing much to my hair except helping it retain moisture, significantly reducing frizz, and making it super soft. That is until I used shampoo one day. At first I used this soap called Black Soap on my hair because it has all natural ingredients, so I wanted to try it out. It didn't completely dry out my hair, but made it drier than Wen. It also made it completely frizz - I had a giant frizz ball for hair. My hair was so frizzy that I ended up washing with Wen the next day just to get rid of it.
The last time I deviated from Wen was about a week ago. To clean with Wen you have to massage it in your hair for a few minutes, and I was too lazy to do that, so I used shampoo instead. This was my favorite shampoo and I used this before I bought Wen and thought it was perfect for my hair because it didn't completely dry it out. Well, I wash with this shampoo and it tore up my hair. My hair ended up dry, frizzy, brittle, hard, and unmanageable. Apparently, I thought that was okay before using Wen, and only after using Wen and going back to my other (cheap) products did I realize that Wen is a much superior product and is definitely doing great things for my hair, even though it's not always obvious - I didn't know until I deviated from it for those two times. I'm throwing away the shampoo.
There is a knock-off called Hair One that's sold at Salley's Beauty Supply. I've heard from people who have used both Wen and Hair One that Wen is far superior. You can also look into buying a cream shampoo and these won't dry out your hair as much as regular shampoos, but they can be just as expensive as Wen. The lather from the shampoo indicates that it's stripping your hair of moisture.
I'll definitely say it's worth the money if you can afford it. I bought mine at QVC.com where it's much cheaper. I've used all the formulas except Cucumber. My hair is dry, coarse, and thick so the Lavender and Tea Tree work best on my hair.
