Hair, skin, and nails are really important in looking good. Oils are very important in keeping these features heathly, and lively. For example scientists are starting to research the effects of lavender on the body and have discovered that lavender has anti-microbial, anti-fungal, and anti-inflammatory properties. Skin problems like acne, eczema, proriasis, are shown partly to be related to Omega 3(flax oil) deficiency. It is important if you want good skin to keep the essential oils in close supply.
