Has any woman here over the age of 30 noticed your hair changing in your 30s or later even?

I've got a fair bit of grey hair and noticed within the past year its gotten a bit dryer in texture. I eat healthy and exercise etc...just curious if other women had changes in their hair in their 30s, later in life, what your experience has been and some steps you might have taken to keeping it nice and healthy. Cheers!
