I'm new to all this too, but what I have come across is that it depends on the product. There are products, I think more towards "jelly" types that indicate if you want to elongated the curl, apply to soaking wet hair. and if you want shrinkage the scrunched into wet hair...so I think it really depends . on the product you are using and the results you want... as far as order of products I believe is LI, then curl enhancer/cream then gel. I would think creams before gels...but hopefully someone with more info will chime in...
