Oops--guest asking about the tea tree oil was me. My Firefox browser doesn't have a cookie, apparently.

There are many products in the world that are here for good reasons. Cleaning products and cleanliness habits have changed over the years, rendering some products obsolete or at least not necessary at such strengths as originally developed. As we realise that the reasons and strengths aren't so good any more, leaving them behind is a prudent thing to do. I try to use detergent without perfume, I look for mild scented soaps and shampoos, and the gel that we use for hair styling is odorless, if possible. Otherwise you have quite a cocktail of smells not only around you to effect others, but to effect your own body.
