There are also quite a few studies that have found essential oils to be helpful for hair growth. One such study, conducted in 2015, evaluated the efficacy of rosemary oil on patients with androgenetic alopecia, or male or female pattern baldness. Patients were randomly assigned to rosemary oil or minoxidil (a medication commonly used for hair loss) for a six-month treatment period. Researchers found that both groups experienced a significant increase in hair count at the six-month endpoint. They also indicated that scalp itching was more frequent in the minoxidil group. (17)
Despite the sudden burst in popularity, essential oils are not a new thing. The ancient Egyptians were among the first people to use aromatic essential oils, incorporating them into their daily lives. Pure essential oils were incredibly valuable and saved for priests and royals. Ancient books such as the Bible also talk about the use of essential oils. According to the book, Essential Oils for Beginners, the Old and New Testament reference essential oils over two hundred times.

DO: Learn to compare apples to apples when shopping for oils. Anise, Lavender, Bay, Cedarwood, and Eucalyptus are examples of the common names of plants used to create essential oils. There, however, are different varieties of each of these plants. To differential these varieties, the botanical name (also referred to as the Latin name) is used to tell them apart. For instance, two different oils are referred to as "Bay essential oil," yet they come from two different plants. The properties and aroma of each oil do differ as does the general cost between the two. It, therefore, is important to pay attention to the botanical name. In the case of Bay, the common botanical names for the two oils used in this example are Pimenta racemosa and Laurus nobilis.
