Rosemary oil is derived from the evergreen shrub rosemary. Traditionally, it has been used for medicinal and cooking purposes. Today it is also found in fragrances, soaps and cosmetics, either for health or for its pleasant aroma. If you are suffering from an itchy scalp, understand how rosemary oil can be used to treat several sources of the problem — anxiety and stress, infections and improper way of cleansing the hair and scalp.


Use rosemary oil for thin hair with an itchy scalp. This hair texture is prone to excess dirt and impurities that can cause an itchy scalp. An old folk remedy is that rosemary oil cleanses the scalp. It is high in vitamin B, calcium and iron, which can help the hair combat conditions such as dandruff, oily scalp and brittleness.


Treat an itchy scalp with rosemary oil if the problem is caused by anxiety. One of the symptoms of anxiety is profuse sweating. On the scalp, excess sweat provides an ideal sit for bacteria, as the hair “traps” the sweat. When the scalp becomes populated by bacteria, it begins to itch. Rosemary oil can be used in aromatherapy to reduce anxiety as some studies have shown that pleasant smelling oils calm the mind and reduce stress. By treating anxiety you may sweat less, and, in turn, have less “itchy” bacteria on the scalp.


Use rosemary oil to treat an itchy scalp that is caused by an infection. Pityrosporum ovale is a type of fungus that lives on the scalp and can overgrow causing irritation and an itch on the scalp. When regular shampoos cannot combat the problem, rosemary oil can be used as a treatment. Studies have shown that rosemary oil has antimicrobial effects. In a study performed at the Council of Scientific and Industrial Research, rosemary oil proved to be useful in counteracting bacteria and fungal infections that were resistant to drugs.


Use precaution when using herbs and oils to treat health problems. Interaction with other herbs, supplements or medications can trigger side effects. It’s recommended that you consult your health care provider beforehand. Bear in mind, rosemary oil should never be taken orally, as it is toxic if ingested. It should always be used in small doses externally on the skin or hair.
