3D US-hair??

Addrrr • 👼🏻👶🏻👼🏻. Trying for baby #2

The us tech said he has a little bit of hair. Is that starting at beginning of hairline or in the neck? Can’t ever tell what I’m looking at in these. Also/ due July 14, do they grow a lot more hair towards the end or does he have about what he’ll have already?
