French police tear-gassed fans before the match on 28 May and some supporters were attacked by local youths afterwards.
Liverpool fans have complained of fearing for their safety in a crush while trying to get into the stadium and of local gangs from the Saint-Denis area descending on crowds after the match, stealing phones and watches and threatening them with knives.
Hogan said the club is working with “a number of expert mental health organisations” who can “offer urgent support to fans” affected by the trouble.
“I can’t say that a day has gone by where I haven’t had multiple conversations with supporters about what happened in Paris,” Hogan added.
“I’ve had a number of conversations and all of them have been very difficult.”
Hogan said 9,000 fans had filled out a form to feed back on their experience of the final but stressed that these were not statements of crime and anyone wishing to report an offence should do so through the French embassy website.
A French government report published earlier on Friday said a lack of preparation for travelling fans, huge numbers of people without tickets or fake ones, and security failures at the stadium were all factors in the fiasco.
The report found that 2,700 Liverpool fans with valid tickets did not make it into the stadium.
Uefa, who have commissioned an independent report on the events, have taken down a statement on their website which previously claimed Liverpool fans with fake tickets were responsible for the issues.
