I'm also a type 4B/A and was dealing with WL hair with tons of SSKs. I primarily wore my hair in mini braids or cornrows but when I wore it out, it wouldn't hold a twistout/braidout or press. I can still do my cornrows and mini braids but now my braidouts last all day and my straight hair lasts weeks without restraightening.
I use a mild, lye relaxer (Motions). I've learned that adding conditioner/oil to my relaxer gives me more texture than if I apply the oil and conditioner directly to my virgin hair before relaxing. I believe that is how I'm able to achieve a blow out texture vs. curls.
The night or two before my relaxer, I pre-twist my hair into the sections I'm going to relax in. Then I can quickly apply my relaxer and smooth with my fingers only. I rinse as soon as I'm finished. There might be a 5 minute delay or so for me to clean up and put away the relaxer items, prep the sink and wait for the water to warm.
I've also learned that if I do the midstep protein, my hair becomes less processed. So I've started doing my protein after neutralizing (3-5 times). I always follow that with a moisturizing DC with heat and then let my hair airdry after rinsing out.
So I don't believe in promoting specific products because we all have different hair. But I believe that that the techniques are important.
One of my biggest regrets when I relaxed my virgin/natural hair is that I left too much texture in it. I was looking to be able to WNG, something I could never do when natural, and I ended up suffering a setback from SSKs. So my advice is if you're gonna do it, try not to leave in too much texture.
Sorry for the novel - I hope this helps!
I don't have a lot of pictures on here but here are my twists before and during relaxing and also a pic of my airdried hair.
