Newcastle second-rower Tyson Frizell has advised Jarome Luai to invest in a hair tie after he conceded a costly penalty for pulling the Penrith five-eighth's locks.
Luai recoiled in pain when the stand-in Knights captain pulled his hair at McDonald Jones Stadium in Saturday night's game and with the ensuing penalty, Penrith moved into position to score the try that levelled the scores.
