yeah my hairs pretty long and I adore it. I don’t use it so much for styling reasons though, more for the health of my hair, so depends what you’re looking for. It’s a very good styler but if you already have a good dryer/straightener/curling iron then it’s not worth the money unless you’re looking to use significantly less heat on your hair.
It works great for my long hair though. You’re meant to dry your hair 80%ish first but I don’t, i usually just dry my hair from wet with the smoothing brush and it leaves it pretty much dead straight but without flattening it like straighteners do, and really soft and glossy.
from my own experience/reviews I’ve read the curling bits seem to work great if your hair usually holds a curl, not so much if your hair doesn’t. Mine doesn’t but I still use them occasionally cos it drops pretty quickly into a nice wave. I don’t notice and difference in the time they hold when I use it on damp or dry hair either so it’s handy to add a few waves quickly on dry hair if you don’t have time to style your whole head. the round brush attachment is great for lifting the root on long hair, though I don’t use it all that often as you can get the same effect with the smoothing brush by just drying your hair upside down for a few seconds.
