@bluenvy you may want to incorporate some type of gel. I think the gel is needed to lock in the moisture. Also think about about shingling either with fingers or even a denman brush (be very careful only use on small sections).
I've attempted the Anthony Dickie method before but it yielded subpar results compared to what I get now.
Shingling and working in sections works wonders for me. It may take a long time to do however I'm only doing my hair once a week. My hair stays moisturized all week very rarely do I reapply products. I will reapply if I feel the need to usually it's just my bang area that gives me problems.
As far as products I find I like to use a cleanser (con argan oil moisture & shine shampoo, as I am coconut cowash etc), a rinse out conditioner (I almost always use Aussie moist conditioner), a leave in (as I am, Camille rose, mop top, shea moisture), and a gel (as I am curling jelly, Camille rose curl maker, mop top curly custard, twisted sister amazing dream curl cream gel).
This may be an unpopular opinion but I choose not to staighten. I think it kills your curls. I haven't gotten my staighten since last year. When I did my hair felt different/limp when I washed it. It took a couple of washes before it felt normal again. I also had anxiety the whole time so for me it's not worth it and it didn't stay straight for very long.
I hope this helps.
