When we look at the data, typically clean shaven or short stubble are the most attractive hair styles to women.

In this data set, a clean-shaven look was overwhelmingly the top choice. However, due to the scoring method, short stubble was ranked first by factoring in the third-choice preferences.

Generally, both a clean-shaven look and short stubble are ideal, but clean-shaven seems to have a slight advantage.

Studies suggest that a stubble length of 4-5mm is ideal. It’s important to avoid the awkward transition phase between short stubble and a full beard.

A longer stubble length reduces facial definition, giving a rougher look that appears less clean and refined.

It's also crucial to avoid stubble that is too short, as it often looks worse than being clean-shaven. Instead of a defined stubble, it creates an unaesthetic beard shadow.
