Inspired by the Timotei thread where someone mentioned that their mum didn't believe in hair conditioner, I realised there is actually quite a long list of things my parents didn't believe in that still leave me, at nearly 50 with DC of my own, feeling like I'm being ridiculously extra for doing every day things:
Hair conditioner as above -deemed totally unnecessary, not a real thing, and drain blocking by my parents. I had long, dry curly hair...
Vitamins -I bought my own as a teen as I thought it might help with acne. They behaved like I was shooting up H.
Make up. My mum believed that all make up (but particularly foundation) was the cause of all skin aging and would tell me (when I was wearing it to hide teenage acne) that once I was 40 I would look older than her as a result.
Tampons. Apparently if you used tampons, you'd have to go for a D&C every year or so due to "build up".
Deodorant. Not necessary if you washed apparently. They considered it something dirty people used in lieu of washing.
Sunglasses, especially when driving. Could make you go blind. Like the reading in the dark old wives tale. As a result my mum spend many a summer gardening with no eye protection and got early cataracts. Yet she still looks at me suspiciously, like I might crash, if I put them on to drive on a sunny day.
Contact lenses -seriously dangerous in their view.
Sun block -they were of that generation that used baby oil and encouraged me to do the same because I was so pale and unhealthy.
Changing job -you got one job and stuck with it or your CV would be ruined forever. And they took this literally, expecting me to stick with chambermaiding as a 17 year old. When I was in a professional role and given rotating training -shifting every 6 months, they were horrified. I'd never work again etc.
Hobbies including sport. They simply did not believe in hobbies or interests unless you were going to make it your whole life's devotion, career or it was going to take you to the Olympics. The idea that you might try something out, and not stick with it was outrageous.
I think my parents might have been particularly odd. There are other examples I can't bring myself to say out loud.
Please tell me other people have similar tales of things their parents didn't believe in...
