How Much Time Do You Allot For Haircuts?

Is it ethical for me as a professional to book more time when not allotted? A lot of stylists I work with book a woman’s haircut to be a half hour to 45 minutes booking (and it’s pretty much on par for how the salon is run) but I prefer an hour to an hour and 15 minutes to conduct a thorough consultation and provide a quality cut. Having their hair done is a big deal to clients and I take pride in quality work over quantity. I have refused to do sloppy work because of time restraints…
