I have very thin hair all over. And I use this product instead of shaving cream and it works the best under my arms. I think that it lathers well and you skin doesn't feel tacky after using. No razor bumps and no ingrown hair.
Olay beauty bars are good but not great. I prefer the body wash over the bars. They tend to dry out and leave your skin tight. They are inexpensive and the smell is ok. I would buy body wash instead of these bars
