How does one choose a haircut?

I’ve never had my hair professionally cut. The closest I’ve ever come was having a friend who was in cosmetology school cut my hair about seven years ago. It was the first haircut after 11 years of religious non-cutting-ness.

Anyway, my hair’s thinned quite a bit in the last couple of years and the length just doesn’t look as good as it used to.

I’m trying to research what the best options are for my kind of hair, but between the eleventy billion affiliate marketing blogs and a thousand monthly magazines trying to pad columns, the amount of contradictory information is baffling.

How do women do this all the time?

Is there a good source for professional information on what hair does when cut one way vs. another?

I’m terrified of commitment. For context I’ve wanted the same exact tattoos for almost ten years and haven’t gone through with any of them yet. Choosing a haircut, I’m sure, won’t take quite that long, but I feel like I’m not making an informed decision yet.

I’m really bad at this whole being a girl thing.
