Always use only the smallest essay since I only have medium length hair. It makes great volume, super lots of shine and makes even dry ends completely disappear without making it worse. Pony is perfectly coiffed, apply on dry and wet hair well. Just buy it, because you have both hands free, it is not too hot, so you can even touch the essays by hand! The scalp or ears do not suffer, especially if you own so that works absolute plus! But curling? probably less. Faith also waves are very difficult. But I also did not want to, so for my purposes perfectly!
