I used the keep the very bottom of my nape shaved (the first time I got my hair braided in HS they did it so I just kept it up) I just started letting it grow out about a year ago. It's too short to braid, but I do a very small flat twist and tuck the end, or use a clip b/c it's too short to fit into my bun.
When I had nape damage, LOTS of moisture and protective styling is what helped me through it. The friction from wearing it down and over processing made it break. I understand that you don't want your hair weighed down, but keeping the hair supple and heavily moisturised + protected could really help with your retention.
