Not sure if this was the kind of answer you were looking for, but my top recommendation is to incorporate new products systematically and to do product or technique experiments.
I do this by splitting my hair down the middle and on one side doing my usual routine and on the other testing out whatever product or technique I'm curious about. That way I have a side by side comparison, under the same environmental conditions (so that I know the difference in results are the products or techniques and not how humid it might have been on one day versus another).
I would also recommend experimenting with sealing routines to keep in moisture (regardless of whether you use butters, oils or silicones to seal). For a long time I was doing the LCO method (before it was named that) and putting the oil on my hair last. In my mind it made sense to put the oil on last to seal in the other products. But I kept hearing about the LOC method, and putting the oil on before the cream. And though that didn't seem to make sense, I did a product experiment and tried the LCO consistently on one side of my head and did the LOC on the other side. And the LOC method, for me, by far had the better results. But I wouldn't have known that without experimenting.
And I learned that sealing is an important step, for me, by experimenting with skipping it in my routine for awhile and just using leave-in's and stylers. Not sealing my hair over time caused my ends to deteriorate much more quickly and my hair was drier and more tangly. So I reincorporated sealing.
I've learned a lot about my hair through experimenting like this. Doing this, I've found what works for me. Some of it follows popular recommendations (ex. finger detangling, frequent deep conditioning, sealing my ends and protecting my hair at night with silk or satin). And some of what I do goes against a lot of the popular hair advice (ex. using a brush, sulfates, silicones and petrolatum).
So my recommendation is to experiment, but do it in a way where you'll be able to tell what actually is and isn't working for you.
