I am not certified in aromatherapy so I do not advertise or suggest using certain scents to affect the client. I do however dab a drop of an essential oil or two on a Kleenex and place the tissue on the headrest bar to create a smell scape, this allows the client to remove the tissue if they do not want the aroma. When using hot rocks I use oil that contains a blend of essential oils I feel is appropriate for the client and season.
