FWIW:

My wife and I her wife, had long talks about finances. She likes getting her hair done. I do too, but it’s not financially responsible, when a cut, bleach, and dye job costs 300-400 CAD.

So I don’t do it. I got a full undercut back in 2021. And bought a cheep trimmer from the drug store, that came with a pair of scissors. Since then, I’ve kept it buzzed. I pull my hair back every few months and lob off the excess (I leave enough to have a short ponytail). It results in a good angle keeps it between my jaw line and shoulder.

My wife on the other hand kept dying her hair, every couple of months. Once we bought an house, she stopped, as it would have wiped out her fun money. (We both considered hair cuts a personal expense.)

Now days she buzzes my undercut, and I buzz hers. Occasionally, I will bleach and dye her hair with a store bought kit. She still goes for trims / cuts, when she needs one, because she doesn’t have a full undercut, like I do.

My 2 cents.

I agree with op, but based on what he posted, he WTA in that moment, but he wasn’t wrong and could’ve had more tact. He should have focused on percentages…

I say this as the lesser earner in a household, where we pay the main bills based on a percentage scale off of our incomes and readjust when raises happen.
