My stick straight hair can't hold a curl, it'll go back to its natural straightness after a couple hours of curling with most wands. I usually aim for waves/soft curls, and I picked it up after I had a lob haircut. Initially this gives me tight ringlets on the second heat setting, a look I wasn't going for. But these curls did last two days on my hair (including showering with my hair up) getting more relaxed as time went on. It kinda got frizzy but I combat that with a little styling creme or hair oil on the ends. I found that curling my hair the night before, I would wake up with those relaxed curls, perfect for rushed mornings. The one downfall of this wand, is how easy it is to accidentally hit the off button while curling. It is not a huge issue since the wand heats up super quickly, but still, between not burning yourself, getting the curl right, the last thing I need is to know that come away with an uncurled strand. I didn't purchase this (perks of living with two sisters) but I'm sure this wand was from the drugstore and wasn't more than 40$ CAD.
How I curl: section off from ear to ear, clip up top layer. Start with bottom section, take 1-1.5 in sections, alternating direction of curls, twisting the hair before coming into contact with the wand, leaving out the ends. Hold for 10-15 secs. Twisting the hair creates a less perfect wave.I always make sure that the front pieces would curl away from the face. Repeat on whole head. Once the curls cooled, run hands through to break them up. I find that since these curls hold so well, I don't need hair spray but I like a small bit of hair oil in the ends.
