Yes, and access to feminine hygiene products is treated as a basic necessity rather than a privilege in correctional facilities across the country.
For inmates who have money on their commissary account, several brands and product types are typically available for purchase. Tampons, pads, and other feminine hygiene items appear on most commissary lists and are generally priced comparably to what you would find at a grocery or drug store. Having funds on the account gives women the ability to choose the products they prefer and stock up as needed.
For inmates with no money on their books, the facility is required to provide basic feminine hygiene products at no cost. The standard issue items may be more limited in terms of brand or type, but access to something suitable is not withheld based on inability to pay. This is one area where the system recognizes a fundamental need and addresses it accordingly.
If you want to support a female inmate with commissary funds specifically for hygiene needs, putting money on their books is the most practical way to ensure they have access to the products they prefer rather than relying on whatever the facility provides. Even a modest amount covers hygiene essentials for a full month at most facilities.
