Thanks for all the responses. I haven't had a chance to come on here in a few days.
I forgot to mention my hair is relatively long. When it was shorter, I actually used to wet it several times a week, but these days even washing loose is not an option.
I've put my hair in loose twists now, and I think I'll probably stay in these for a couple of months (redoing them every 2 weeks I think). I've been wetting every other day, following up with conditioner and sealing.
Like you Ricotdorothy, I was a bit worried about the twists meshing (especially as they're quite loose), but so far so good. I've been taking some down randomly to see. I think the detangling properties of the conditioner stop them from locing. So I'll continue for a while and see how things go. Make sure to report back.
