TencentARC/PhotoMaker · Hairstyles can be horizontally flipped in the output images

I tested this against both male and female training images. For example, say it is a woman with long blonde hair and her hair is parted on the left side of her head. The AI does seem to study and remember the hairstyle so that it will replicate it for the output images.

However, what I noticed in the output images is that about half the time, the hair is parted on the RIGHT side instead as if the AI is generating a mirrored version of her hair. Other times the hair is recreated correctly with the hair parted on the left side.

I suspect that the face might also be mirrored too but since the face is usually symmetrical (unless the person has a tattoo or mole only on one side of the face) then it is not as noticeable as the hair.
