Dimorphism
Hair

How the hairline reads, and how hair length and facial hair are treated.
How it's assessed
Each region below is graded for how strongly it reads as typical for the sex you select, on a 1 to 10 scale against people of the same sex, where 5 is typical. A region that reads strongly as the other sex scores lower. The full explanation is on the Dimorphism overview.
Hairline
In men, a strong, straight, mature hairline reads as masculine, and a low, rounded, juvenile line as less so. In women, a soft, lower, rounded hairline reads as feminine, and a high or receding line as less so.
A fringe or hat can hide the hairline, in which case the model has to estimate it, so keep your forehead clear in the photo.
Hair Length
Hair length is a style choice, not a structural trait. For men, short to medium hair that is neat scores well, and it is only marked down if it looks unkempt. For women the score reflects how well the style suits, and a short or long cut is never penalised for length alone.
Facial Hair
For men, facial hair is grooming rather than a requirement: a neat clean shave, stubble or a full beard all score well, and only patchy or messy grooming scores low. For women, smooth skin with little to no visible facial hair scores highest, and visible coarse hair scores lower.
A note
Hair is the most changeable part of Dimorphism. Hairstyle, grooming and facial hair choices affect these items far more than anything about your bone structure.
