Oh, to have natural waves or curls (or shine) instead of poker straight locks! How lucky you are. I'd grow it.
I think long hair suits most face shapes, (maybe not long/thin) regardless of age. I don't agree that short or mid length makes people look younger. Often, less than pretty neck and ears are revealed.
It's easy to tie it back or up, plait it - or put it in a twisted 'hat platform' style - or leave it long, maybe tucked behind the ears!

Being asked for an honest opinion


, I love the picture you have sent, thank x
Not good at inserting photos, but I will try...sometime. So my advice, OP, is to find a new stylist and be assertive about your preference.
