The actress was sentenced to 90 days behind bars on Tuesday for violating the terms of her probation and is expected to surrender herself on July 20.
Her father, who previously spent three years in prison for insider trading, told US Weekly that he and fiancee Kate Major will do everything they can to make Lindsay's time in jail more bearable.
"It's not going to be a good experience for her. Right now, she should be working on rectifying the situation and getting better," he explained.
"It's just a horrible experience. Twenty-three hours a day, she'll be locked up. I'm going to get her out of that cell as much as I can. And Kate will be there, and we'll work to get her out of that cell as much as possible."
Michael added that Lindsay is currently refusing to speak to him because of his insistence that she get help for an alleged prescription drug problem.
"She knows I still want to throw her in [rehab]. I've been trying to tell her how much I love her, that I'm behind her, that when she's ready, I'm ready to help her," he said.
"If she would just realise that what she's taking is toxic... Dina has denied that Lindsay is on prescription meds. Lindsay has denied that she is on prescription meds. Her friends have. Everyone has! And look at her! They're lying."
Michael recently admitted that he was glad to see that Lindsay's lawyer Shawn Chapman Holly had resigned.
