Now don't get me wrong, I do on occassion butcher the nog' when I get too eager in my morning shave ritual. Speed and the neck-meat, mmmmm.... not a good thing! But I actually have less head irritation being sly. With hair I have these outbreaks of little sores. Yikes! I used all sorts if differing shampoos (tea tree seemed to work best...) but yikes! Sly is much much better. I would rather deal with the occassional nick or burn.
