And so it is that often, I find myself pondering the wonders of the universe and all of its glorious minutiae. (Let's just say that I rarely get bored.) And often, I think about things that just don't quite make sense to me, and I question whether I'm the only one, or if others are perplexed as well. In other words, is it just me?
So I'm starting a new feature here on my blog where occasionally I will bring up a topic that I've been pondering, just to see if it makes sense to anyone else. Comments are wholeheartedly welcomed but not necessary. I think I'll be happy enough just knowing that a few people out there might be thinking along the same lines as me. Strength in numbers and all that.
My first topic for consideration is... hair dye. Specifically, the difference between permanent and semi-permanent colour. I didn't say that this was going to be earth-shattering, important stuff, did I? :-) Now I know that one of the things that sets the two apart is that with semi-permanent colour, you can only make your hair darker, not lighter, because it doesn't contain any peroxide or ammonia. That part I get, but what I'm questioning is, how long it lasts.
They say that "permanent" colour lasts longer, but that doesn't make sense. Here's the quandary: If our hair grows out from the roots and not the other way around, the old colour will start to show at the root at the same time, regardless which type of colour we use, right? Therefore, in order to last longer, hair dye would either need to control how quickly your hair grows, or be able to penetrate your scalp and colour the hair beyond the root, which obviously, it can't.
It seems to me, then, that there really is no difference between how long the two last.
Does that make sense to anyone else, or is it just me?
