I don't know about Florida, but in Cali defendants have the right to be presentable. They do have full salons in prison....I don't know about jail.....if you look at several male trials, you'll see that they clean them up for their court appearances....shaves, hair cuts, etc., wish I could remember the most recent one where the defendant was heavily bearded with long scraggly hair......he was in custody and arrived in court looking entirely different......short hair, business suit, clean shaved.....they must have to provide the same services for women because their presentation is part of their defense....FWIW
One of the first ones I thought of was Melissa Huckaby in the Sandra Cantu case. She was transformed into a different person the way her hair had been cut and styled, almost unrecognizable, at her appearance in court.
