Eyebrow Texture Help

Eyebrows aren’t displaying properly. The lashes are solid, instead of being individual strands. Eyebrow and eyelash textures are one file. If I use the .png versions of the texture, it’s black. Can anybody help?

Node setup -
Image texture > Base colour (Principled BSDF)

Image texture > Normal Map > Normal (Principled BSDF)

If there was a link to a .blend with the eye area and the image packed in the .blend, maybe.

It does sound like it’s missing a mix with transparent shader and image alpha as mix factor to make the geometry transparent. The brows might be mapped on the head itself, and mixing those in colors or shaders with image alpha as a factor should do it. But that’s enough guessing.
