twistouts in my experience are more defined when I use a gel. just a moisturizer will make it more bushy or frizzy which i dont mind if thats the look i going for. For a defined look I do my twist out with 6 to 8 flattwists going back( like cornrows)...I use sebastion wet liquid gel and it keeps it defined. when dry I take it out,very slowy as not to disturb the pattern..
