There's no reason to be annoyed. You said you wanted realistic ... but then you say Desir actually is realistic. That sounds to me like you have what you want; you just can't turn it inside out and upside down.

Now, if you really want realism, compare your Desir renders (or for that matter, the vendor's own promo renders) to photographs, or better, real hair on people around you. There is no comparison, even though this is, as I said, a good hairstyle so far as transmapped hair goes. Heck, a very good one.

But.

The hair strands have movement, and that's great, but they don't look like real hairstrands. (This is particularly obvious when you look at the last few inches of the hair.) It looks like the work of someone really skilled with a quality Photoshop brush.

Likewise, it has some realistic colours painted into the texture (kudos for not choosing oversaturated colours that a lot of people do), but it doesn't interact with light the way real hair does. (Strictly, neither does Poser dynamic hair, but it's far superior to this, given good material settings, which is why Carodan's gallery images look so realistic.)

The bottom line is that transmapped hair serves its purpose, and is an easy way to get to a certain point. Beyond that level, however, it really cannot take you any further in terms of realism.
