She could still be itchy from other reasons than fleas. You didn't mention the condition of her skin, but if it seems irritated at all, she may have allergies to other things. Tensing of skin could also indicate that she is painful somewhere along her neck or back. Ideally, she should be seen by your veterinarian to determine if there is a medical reason for this tension. If she doesn't react in any other way than to tense her skin, it may just be a quirk of hers. In pets of all ages, fleas, food allergies and exposure to chemical irritants such as cleaners and soaps can be a cause. Any one of these may not be enough to trigger the breakouts, depending on how sensitive your pet is, but a combination can be enough to start the itch-scratch cycle. Finding out the cause and eliminating it is the best course of action. With flea allergies, if your pet is sensitive enough, a single bite can cause them to break out scratch enough to tear their skin. Check for fleas, a flea comb is a good way to find them. Look for fleas and/or tiny black granules, like coarse black pepper. This is the flea feces, consisting of digested, dried blood. Sometimes you may find tiny white particles, like salt, which are the flea eggs. Applying a good topical monthly flea treatment and aggressively treating your house and yard will help break the flea life cycle. Food allergies are often caused by sensitivity to a protein in the food. Hill's Science Diet offers some non-prescription options for sensitive skin as well as prescription hypoallergenic foods for more severe cases. Royal Canin carries limited protein diets that may also offer some relief. Your vet can recommend a specific diet that will help.
