This is not the lights' fault - even though this effect seems less visible with some lights. This problem is the reason why I had to issue updates to all my hairstyles as freebies, and also P11 and P12 materials for the latest ones separately. P12 wasn't understanding anisotropic highlights the way P11 does. Latest versions seem to have corrected this.

Try updating your P12 to the latest version. If that doesn't solve the issue, then I'm afraid you'll have to tamper with the materials. Ghostship2's hair materials work wonders in P12.
