Every time she sheds look her over, the most important parts are the eye caps and the tail. I always look at the tail very carefully, if there is a little bit still on it you can usually just roll it very gently between your thumb and index finger and it will roll off. If not, soak it for a few minutes and use a washcloth and try again. Once it turns brown it won't heal, but you can prevent it from happening again by carefully examining it and taking care of it before it becomes a problem.
