Going back to the female dress code at my previous place of work; both heels and makeup are potentially harmful to women. I've seen many slick TV spots put out by the big oil lobby that say, basically, that there is no need to feel negative about our reliance on oil since petroleum products are in so much, including cosmetics and hair dyes. The FDA is (was) doing what it can, but many ingredients in cosmetics are unregulated. If researched, you find statements like, "In such low quantities (in cosmetics), harmful ingredients are not likely to cause harm in humans." But women use (or are required to use) these products daily over decades of their lives. It is impossible to find definitive answers about other harms in cosmetics (including carcinogens), because what would that say, that cosmetics should be avoided? The horror!
Why is it socially acceptable for men to go gray, but not so much women? Answer: male domination.
I saw Jane Fonda on last night's Graham Norton show. She's turning eighty in December, but looks like she's in her late forties or early fifties. I believe that there is no way she'd be getting all the work coming her way if she had not had all that work done in this male-dominated society. Of course it's her choice, but there's a lot of pressure. They showed a current image of her with her costar from the sixties, Robert Redford, from an upcoming film, and the apparent (but untrue) differences in age are stark, but perfectly socially acceptable.
This true double standard could only occur in a male-dominated society, the source of so much harm, in so many ways, toward women.
