Hi Alana, My curls last around a week, but I usually wash my hair 2 times a week. I use the 20mm long barrel which is slimmer so it makes tighter curls. I use mousse and dry until 90% then use the round brush and then the barrel. Before bed I put my hair up in a sleepytie dupe I got from amazon. My hair is naturally straight. Great video and excellent tips ❤it.
