I find that short term protective styles are the best for me. I have not mastered low manipulation styles, so I do those rarely. And long term styles wreak havoc on my fine strands...so I get the most length retention from short term styles.
Same for me! I have to wash my hair; I can only go, at most, two weeks, and even that is pushing it. So it's better for me to do two-strand twists for a week, wash, condition, and retwist, than to do a month or two month long protective style
