I have straggly hair...it is long (a sprinkle of grey). I am absolutely hopeless with doing anything with it...I wash, comb it and let it dry. Is there an easy way to make it look more cohesive? So it all waves together (maybe like Kate Middleton) Is there a ’thing’ I could have done at the hairdresser to make this happen (I don’t really ‘do’ hairdressers normally!) I’ve tried a babyliss big rolling drier but can’t get the hang of it. Thanks!
