My mom is a hair dresser, so I'm a bit biased.
I used to cut my hair every few months when it grew long enough again, do crazy hairstyles, dye it all different, colours, etc. She always said "Well, if you don't like it.. Hair always grows back."
Right now I've had the same colour for a few years now, dying it requires too much maintenance for me anymore. But I do get an inch or two off every month or few weeks.
Although my hair is consistently past the bottom of my shoulder blades, but not much further.
Except lately I decided to do the hair thing where people shave the one side of their head, except I did just a little patch.
Turned out pretty good!
P.S. Lovely, your hair is gorgeous and so are your pictures.
I like the new hair!
