When my wife lost her hair to chemo treatment for her cancer, I thought a good supportive husband would take his hair off. Skull shaver Pitbull Gold made it possible and, it did such a good job at keeping my skull shaved, many people asked me to keep my skull shaved. Alas, my wife's chemo is done so I am growing my hair back (hoping it comes). I still use it for my face and it does a great job there too. Thanks skull shaver for making an excellent shaver and for helping me help my wife. Love the product.
