Can I just ask a barber to do whatever?
While it's generally acceptable to give a barber some creative freedom, it's important to provide them with some guidance or parameters to ensure you're both on the same page about the desired outcome. You can express your preferences in terms of length, style, and overall look, and then let the barber use their expertise to achieve that look in the best way possible. However, if you're completely open to any style or change, make sure to communicate that clearly as well. Keep in mind that communication is key to ensuring you're happy with the result.
