light and hair

[blast]

Hi everyone.
I'm making an underwater scene
I'm using a corona hair material (and tried with a standart corona material ) .
and I'm using ornatrix for the hair.

In fact even if I move the light nothing change on my hair . and I've got caustic every where except on my hair.

If someone already did that ....

I'm sorry, but I don't understand this report. Can you please share some image showing the issue?
