Hi There, I am currently tackling this problem myself. (I am irritated that my grays are not as smooth as my regular brown).
What I’m doing with clients is taking medium hair and going back to the curling iron, so they get the Eva Longoria look. Also…the blonde on Desperate Housewives is sometimes straight sometimes curled…and that is a very relate-able current look for women over 40.
Long hair is iffy. This is not what women want to hear, but it is true. Once hair is past the clavicles if your face isn’t young-looking and your hair isn’t luxurious it is often just not flattering. But extensions do help, and can make over 40 hair look a little less over 40.
The problem is the texture. Texture changes (as does face/weight/body proportions) and just blow and go hair isn’t as easy as it once was. You kind of have to create the illusion of ‘blow and go’ with products that have protein in them (to strengthen the hair).
Another a reason shorter hair tends to work better is because it not only looks like you didn’t have to work so hard, but it still looks good later in the day.
If it is longer, make sure it’s shiny. (Using the curling iron, flat iron, etc. helps) It can look sort of Farrah if you don’t’ start curling at the base first and click the hair through, rather than pulling the curling iron to the ends and wrapping it up.
