Ever consider simplifying your hygiene routine? I'm not suggesting you stop showering or flossing your teeth. Please, don't do that! ;) I'm trying to get you to question things you've always seen as the norm.
I actually don't have a groundbreaking reason for shaving the left side of my head. I thought having an undercut would be rad, and it is. So I'll continue spending 45 seconds every 3 weeks maintaining my punk do.
On to more important things, a brief history of women shaving their underarms: In 1915 Harpers Bazaar showed an ad with a woman in a sleeveless dress. If you wanted to look great in this new fashion, you needed to "remove objectionable hair". And so, it became A THING, and most American women have been removing their bodily hair ever since. Here is a video that explains this history in 1 and a half minutes.
So why did I, myself stop shaving? It started to feel like a strange use of my time, removing hair that grows naturally on my body, and causes me no physical harm. I calculated that the five minutes per week I've spent shaving my legs and underarms has added up to over 100 hours over the course of my life. That's four entire days of my life spent shaving!
I actually started shaving at the first sight of a hair under my arms at age 13, and so in 22 years of shaving, I had never actually seen what it would look like to NOT shave. After all those years of prickly stubble, I enjoy the soft touch of my hair.
More importantly, I got tired of feeling embarrassed about the natural state of my female body, often apologizing to others for being hairy on those weeks that I forgot to shave. As if I had offended them by letting hair show. I'm fairly certain no man has ever apologized to me for having hair on his body (and I wouldn't want him to). In my mind it's like this: marketing people stand to make a lot of money making women feel ashamed of their body, and selling products so we can "improve" ourselves. Actually, now that I do less things to myself in an effort to "look pretty", I feel prettier than I ever have before.
I was a tiny bit afraid that my changed look would scare my husband from being attracted to me, but we are still A OKAY at loving on each others bodies :)
Moral of the story: if you like shaving, who am I to stop you. (I won't!) But wouldn't it be neat if we all made room for one another to live in our bodies, just as they are, without constantly changing ourselves? That would be beautiful.
