That's good you already have a silk scarf! I usually use a bonnet for myself only because a scarf falls off during my crazy slumber and the bonnet surprisingly never has lol. As for dryness, how often do you moisturize your hair and what do you use? There are some people who wet their hair and then seal the moisture in with an oil or hair butter (shea for example), I prefer avocado butter.
As for the keratin treatment, I've seen quite a few mention those on another site I go to-naturallycurly-and some have said it did nothing for their hair; results seem to be varied? I've not tried one.
Ugh, knotting! >.< What works for me is finger detangling while I have my leave in conditioner globbed in my head. Some prefer to use a comb, while others may use a denman brush. My hair doesn't tangle often thank goodness, but there's the occassional knot! If you find that your hair likes oils or you are looking for strengthening your hair and decreasing hairfall you may want to look into incorporating aurvedic methods into your regimen. This thread would prove helpful in that case:

One thing you might also want to do is assess your hair on its: porosity and elasticity. There are tests all over the place that you can use.
There are definitely lots of products to choose from and lines specifically for curlies out there; just have to test out and see what works for ya!
Whew, sorry, that was a lot-it's all ramble, but I hope something helps!
