i dont comment on royal old ladies, because i find it "normal" to only wear 1 or 2 hairstyles when your reach a certain age, my grandmothers are the same and now even my mom doesnt change much.
on younger generations, my opinion is the opposite.
Princess Victoria wears ALWAYS a ponytail, and even though she can bring wonderdull updoos on galas and similar events (weddings, etc...), her ponytail appears regulary and making her hair down loose a supposed legend.
Princess Lalla Salma rarely wears updoos and wears her hair almost the same, but her case is diferent, her hair is always well arranged, so beautiful and elegant, and in her i much better perfer that way than a diferent hairstyle.
Catherine, Duchess of Cambridge is a totally disappointment for me, she has such a nice hair and why not try diferent hairstyles with it? always the down with curls and thus always touching it. why not try more updoos? ponytails? braids? it totally sads me.
on royal children, as they are just kids i dont take it to hard, they dont need arranged hairstyles. but i must comment a few.
Letizia does always the same haistyle for her daughters Infantas Leonor & Sofia, why is it always a braid to one side or "hook" aplication to one side? does it not hurt the girls to use always a braid?
Princess Isabella was using her hair long before, it was not pretty on her and it made her look older, thank god Mary cut it short and made her daughter looks so cute. Isabella looks so much better now and shes looking more prettier since her mom gave birth to the twins, also since then her fashion style got way better!
Hair can change so much a person, its their identity, their own personal style!
