I wish I could give some advice here, since I damp bun every time I wash my hair, but I've never used any of these products, or gel. Gel makes my hair feel stiff and crunchy and I don't like that. Instead I use oil, or a mix of oil, aloe vera gel, glycerin, and water.
Anyway, just showing support for my fellow damp bunners and I hope you found the advice you were looking for.
