My husband went to a family funeral last week and spend the night, I had to work so did not go with him. When he returned, I saw suddenly there is a bottle of Dettol antiseptic liquid in our bathroom. I asked him about it and he said it was at his mother's house and just took it to use when he shaves his hair. Last night he was getting ready for work and after he showered, I could smell the bathroom reaking of Dettol. Why would he suddenly be bathing with an antiseptic? Is this something I should be worry about?

Forgot to mention that he has not shaved his hair yet, so why the smell in the bathroom last night?
