Does anyone know of any good sources for burdock root oil? Is it sold diluted in a carrier oil or is it sold as a EO? I have heard that burdock root is good for promoting hair growth and thickness, and would like to try it. Has anyone tried this? (I did a search but did not come up with anything on just burdock root oil.) Good, bad, indifferent? Any suggestions on where to buy it and how to use it?
Thanks!
