Hi There, your question is not stupid, actually it's a very good point you brought out that never occurred to me. My guess is that moisture may mean moisture on the hair superficially but hydration may mean moisture absorbed into the hair. If you're thinning, then Tea Tree is really good for that, Chaz would probably say stay with it and use the Tea Tree oil at night. Just use the dropper and apply it to scalp and massage it in. I use the oils and I don't need anything to cover my head, it doesn't rub off. Don't feel bad, on very humid days I get frizz too. I use the replenishing spritzer to try to tame it. Remember curly/wavy hair will tend to frizz way more than straight hair. The styling creme....I think it's the oils that are in them that make them heavier than the others. I believe Sweet Almond Mint is for coarse hair and Pomegranate is middle of the road, Cucumber and Lavender are lighter. As far as any tsv, I feel it's just a matter of preference. I have hair that's just about to my waist, I don't color, it's wavy and turning platinum and I use any one I choose. You really can't make a mistake it's just make sure you really use enough to cleanse and if your hair is fine not too much leave in and not too much styling creme. I'm sure other posters can add their thoughts. I learn by trial and error. I've used Wen for four years and it really does make hair stronger and imparts deep shine, it really is remarkable. Women of color don't have to use chemicals too, they only need to add enough leave in and styling creme and their curls will be bouncy and soft and not dry. I hope this helps. On QVC's site, you know, where the Wen stuff is, next to each item (most of them) there is a link video just click there and you get the little video where Chaz is showing the item. Good luck, my friend.
