I have fine hair that used to be thicker, but I think due to aging (and hormones), it's not quite as thick as it used to be.
That said...if you have some sort of underlying medical problem, or just natural aging and hormone changes (like me), WEN can only do so much. I have been using it for quite some time, and am very pleased with how strong and shinny my hair is. I don't expect miracles and know it will never be as thick as it was 20 years ago
Since Shaunac bumped a list of abbreviations I won't go into that, but yes, we regulars get in a hurry and instead of typing out the full scent name like Tea Tree, we type TT. or instead of cleansing condition or styling cream, CC or SC.
My advice, try the cleansing condition first and see if it works well for you. Each formula addresses a specific hair issue, but there are several that are universal - Sweet Almond Mint, Pomegranate, Bamboo Green Tea, and all of the seasonals (these are limited edition scents, the current one is Winter Cranberry Mint). There are combo packs where you can buy three or more different scents to try them out. There is usually a combo for thin/fine hair.
If you just want to try one, I would suggest Sweet Almond or Pomegranate. If you need extra moisture, I would suggest Fig. There is a really nice set with Fig available right now, which includes the oil. Some people cleanse and then add a pump as a leave-in. I would suggest trying it without the leave in at first (as I find this weighs my hair down, although some people swear by it). Also, for faster growing hair, a lot of people swear by Tea Tree.
Oil you say! Yes, Wen has really great oils that do a lot of wonderful things. I use a dropperful a couple of times a week massaged into my scalp. It helps make my hair stronger. I also use a few drops (nearly every day in the winter) to help with flyaways and dryness on the ends (since I blow dry and frequently hot roller my hair).
The styling creme is mostly for heat protection, so if you don't use hot tools, this is probably not something you need to try right away.
You use a lot of product -although when I think about the total amount of shampoo plus conditioner I used to use, it's not that much more product, I just use it all at once instead of three steps.
As for me - I use almost every scent, but then I am a beauty junkie. I have tried every seasonal, there are some that I like, some that I will never buy again. Also I live in a climate that is really dry in the winter and really humid in the summer, and so I tend to change formulas with the seasons. If I had to choose two scents, I would use Tea Tree in the summer and Fig in the winter.
