I use ORS Olive Oil No Lye Super, I only mix half of the container for touch-ups, but there's always still at least a 3rd of that left over when I'm done. I only stretch 8-10 weeks though, and only relax my nape like every other touch-up or less. Edges probably every other touch up, depends on how they're behaving. I also use Affirm Protecto all over before I relax.
