Evelyn Lozada has a few words for Chad Johnson after his arrest for allegedly head-butting her -- first, stop blaming me ... and second, get help for your problems, now.

Evelyn tells TMZ, “I am deeply disappointed that Chad has failed to take responsibility for his actions and made false accusations against me." As TMZ first reported ... Chad told police that it was Evelyn who actually head-butted him during their blowout argument Saturday night.

Chad was arrested and booked for domestic battery.

Evelyn also says ... "It is my sincere hope that he seeks the help he needs to overcome his troubles. Domestic violence is not okay and hopefully my taking a stand will help encourage other women to break their silence as well."
