DESCRIPTION
Rosemary has had a considerable revival lately, mostly as a scalp and hair oil - a few drops diluted into jojoba or castor oil, massaged in and left before washing. It is worth saying plainly that it needs diluting; undiluted rosemary on a scalp is a fast route to irritation. Beyond hair, it is a bright, resinous, distinctly herbal oil for the diffuser, and it holds its own in a surface spray. A 25ml amber glass bottle, which at a few drops a time is a great many applications.
