Where do y’all draw the line at beauty services?

Edit to note that I have a corporate job and do a lot of dinner and business development events, galas, etc with clients and potential clients in a major city. I am a female. Hoping to hear ideally from others in a similar position.

I am trying to do a “no buy” this year, and haven’t set strict rules for myself yet other than I’m only allowed to pay for things in physical cash. (I need to get out of credit card debt and build a savings account as well as save for some home improvement projects). Convince me to cancel my upcoming haircut (and do it myself based on a you tube video) and skip the Botox appt that makes me look so much more refreshed and attractive? Or tell me why these things are still ok?
