Premier League referees have been told to change the way they judge hair pulling after three players were sent off for the offence last season.
Officials will also be asked to place a greater emphasis on grappling and holding inside the area after it became commonplace on corners and set-pieces.
The measures were agreed at the Premier League AGM earlier this month after consultation with the game improvement advisory board.
All three red cards for hair pulling came through a video assistant referee review, and led to criticism from the managers of the players involved.
Everton's Michael Keane, Manchester United's Lisandro Martinez and Sunderland's Dan Ballard were all sent off for hair pulling after a VAR intervention.
United boss Michael Carrick called it "one of worst decisions I've seen" but lost an appeal to get the three-match ban overturned.
Stockport County defender Josh Dacres-Cogley was dismissed for the offence in the League One play-off final too.
But from next season, not every time a player is seen to pull an opponent's hair will a red card be shown.
Instead, greater emphasis will be placed on both the level of force and the intention.
Everton boss David Moyes criticised the red card shown to Keane, claiming his player had received a ban for "absolutely nothing".
However, the new guidance does not mean hair pulling will suddenly be tolerated.
It is likely that Keane would still be sent off - his holding and pulling the hair of Wolves' Tolu Arokodare deemed violent conduct.
But Ballard and Dacres-Cogley would probably be judged to be yellow-card offences - though the VAR cannot intervene for bookings.
The change is in intended to give more latitude to players who may accidentally hold onto an opponent's hair.
