Reason for shorter hair, longer hair more hastle, people
are hitched so attracting someone else is less important and
one important thing, hair density.
Most women slowly lose hair density, especially after menopause
(estrogen and progesterone protects hair density)
as they age and by the time they hit 50, long hair will make the
hair look very thin and the part will show a bit of the scalp.
So, shorter hair for those women, by the time they hit 65-70,
short hair alone is not enough and you have to curl them
also to hide density problems. That's why many older women
have those perms. I hate them.
Also, is in all things, there's peer pressure, why on earth would
you want to look "your age". Never understood why that would
be a good thing.
