The Egyptian has scored in the Potters' last two Premier League games but was booked both times for his over-exuberant reactions.
“He jumped over the barrier and he should be aware you're not allowed to do that," said Hughes.
“Maybe that was his substitute for taking his shirt off and didn't realise he'd get booked for both!
“You have to be careful, if you do that and then mistime a tackle then you're at risk - so it's crazy to do it.
“I quite like it, it shows the joy of scoring, it's part of the show so why wouldn't you do it?
“But the powers that be frown on it unfortunately."
The Egypt international signed for £5m from Al Ahly in July 2016 and has made 15 Premier League starts and 16 substitute appearances but had not scored until his goal against West Brom.
Hughes added: “We like Ramadan, we like this attitude to his work, he's desperate to play, he's got a real youthful enthusiasm and a lot of experience - albeit in a different league.
“You sometimes forget how young he actually is, he's still learning his trade.
“And now he's having an impact in terms of goalscoring, which we feel he has the potential to get better at.
“He's a positive guy who wants to get at people and take them on, which we encourage."
