Choose the length you want to explore, which may be your current length or a possible change. If you are curious about a shorter outline, selecting Short makes that question visible. If you mostly want a new styling mood and are not considering a cut, you can stay near your familiar length or leave the choice open. The finder does not infer your starting point.
Read a length label as a broad category rather than an exact cutting measurement. Open a result to understand where the fullness, front and perimeter sit. A short reference might interest you because of its clear neckline, while the useful everyday experiment could be gathering longer hair away from the neck. You can borrow that detail without deciding on the same haircut.
