Each item must be 3.4 ounces or less and must be able to fit inside a one-quart size clear zip-top bag. The limit is one bag per person. Typically, travelers put their toiletries in the bag such as shampoo, hair products, make-up and toothpaste.
Can I bring full size shampoo in my checked baggage?
Liquids, gels and aerosols must be placed in containers no larger than 3.4 ounces, with all containers fitting into a single 1-quart plastic bag. Those limits don't apply to checked bags, so pack full-size containers of shampoo, lotion, toothpaste and other restricted items in this bag.
In these notices the TSA is making the assumption that the shampoo in question is a liquid or a gel. Liquids & gels are restricted in carry on bags. You can bring liquid shampoo in your carry-on luggage in bottles that are less than 3.4 oz (100 ml). That doesn't mean that you can't bring more than 3.4 oz.
