Hair style

So I currently have an undercut that is cut about an inch from the hairline starting from one ear to the next. I was thinking about either 1, grow it out and get a shorter haircut or 2, extend the undercut so it is more visible.

I have thought about extending the undercut as I kinda unfortunately wear my hair in a low ponytail so I can comfortably wear as I ride my bike. My hair is wavy but I have been curling it.

I have also thought about cutting it short as I have seen some older photos of myself and I enjoyed the look.

I am debating on which one I should do. The undercut will be cheaper as once it is extended, I just will have to have someone in my house cut it every month inline having to go to the hairdresser every month or so. However, I will-am pretty sure I'll get more euphoria from the short hair.

I would like some input from strangers on the Internet.
