We asked Lesley Stahl, Mary Wells, Jane Wagner and Sheila Nevins about their hair, its care and feeding.

LESLEY: When I get up and do my hair, I spray it so completely — with cement — that if you called me at five o’clock it would still be cement. I’d be able to run out.

MARY: It doesn’t look that way.

JANE: No, Lesley, your hair looks gorgeous all the time. It looks layered and so thick.

LESLEY: This business of just getting it in place and not having a hair move started when I was covering the White House for CBS. I could be called on to be on camera at any second. No time to play around, not even, really, time to put lipstick on. So you had to be ready at any point during the day. Cement was the solution I came to and it worked. And so I just keep doing that.

SHEILA: You don’t have to have it done by anyone? You can do it all by yourself?

LESLEY: Well, you have to learn to do that.

SHEILA: I can’t. I can’t. I can’t learn to do my own hair.

JANE: I sometimes use a root-lifter spray, but what good is it if your roots stay up but the rest of your hair falls down limp? Why shouldn’t you use the root lifter all the way up?

SHEILA: Well, it depends how I want to look. If I want to just go to work and schlump around I can do it. But if I want to look good, I have to be primped up by someone else. I can’t primp up. I can’t use a blow-dryer. I can’t do any of those things properly. I don’t know how people do it. You actually blow-dry your own hair?

LESLEY: Yes.

SHEILA: I am just hateful. I mean, it always looks good because I work on it outside the house. But inside its very hard to — I’ve tried. People always ask me what’s wrong with my hair when I do it by myself.

JANE: The secret is a good haircut, but I’ve never had one in my life. In fact, my bad hair days are usually when I’ve been to the beauty salon and had my hair cut.

SHEILA: No, no, but it also depends on whether you have straight or curly hair. You see, I have curly hair. But I have the affect of straight hair. So I’ve been fighting whatever it is I was born with my whole life, you know, by either putting rollers on when I was a kid and sitting with that big blossomy hair-dryer, or finding the cheapest place to blow-dry my hair. Hair is a major issue in my life because I can’t just jump up and go, because I don’t know how to do it.
