Unfortunately, you won't know what works for you until you try! It's really a matter of trial and error. Struttswife has a great e-book that I can't recommend enough. It really helped me figure out my own hair and how to manage it!
Here is a link to Jessicurl's info on alcohols
, which ones are good and which ones are bad (click on "Ingredients Philosophy").
But you don't necessarily need to be well into CG in order to start figuring out what works and what doesn't. I realized pretty quickly that glycerin makes my hair look wet and greasy. I looked at the ingredient list of those products and realized glycerin was pretty high up on the list for each one. So now I look for the glycerin free labels. (The labels don't mean that it's something everyone should avoid because it's bad for hair in general, by the way--other than sulfates and silicones. it just means that it's something a lot of people want to avoid for themselves because it doesn't work for them.)
On the other hand, my hair can handle larger amounts of epsom salt (magnesium sulfate) than others as long as I add some aloe to counteract the dryness, but nothing compensates for how dry too much of the chlorides makes my hair.
It can be overwhelming, so start with the general recommendations and go from there. Avoid sulfates and silicones for now and don't worry about 'quats, etc., yet. You would probably want to avoid proteins and focus on deep conditioning since you have coarse hair. Butters and heavier oils, like coconut oil, would work better for you than they do for my fine hair.
Otherwise, as you go you'll notice that certain products or treatments turn out "wrong" or don't really work. It takes a little bit of detective work (ie looking at the ingredients to figure out which one your hair doesn't like), but you'll figure it out.
One thing that helps is looking for others here who have similar qualities to their hair and see what did and did not work for them. If nothing you do seems to work, look for any common ingredients that are higher up on the list and do a search to find out what they do to hair. For example, salts can be drying, others, like agave or honey, can make people's hair sticky or crunchy.
Good luck and HTH!
