The Benefits of True Lavender Oil for Hair.

Used since ancient times for its olfactory qualities, true lavender oil also has several beneficial properties for the hair and scalp. Its antibacterial action, combined with its soothing properties, makes it an excellent purifying agent. Learn more about its hair care and even hair growth properties.

Overview of True Lavender Essential Oil.

The essential oil of true lavender (Lavandula angustifolia) is extracted from the flowering tops. It grows between 600 and 1,400 meters above sea level, in the sunny valleys and mountains of Provence, and certain regions of Spain and Italy.

The flowering tops of true lavender are used to make essential oil by steam distillation (hydrodistillation). It differs from lavandin, a hybrid between true lavender and spike lavender, by its low yield.

Mixed with other ingredients, true lavender oil for hair brings softness and it soothes the scalp. It is used in the composition of several hair care products such as lotions, shampoos or masks.

The Benefits of True Lavender Oil for Hair.

True lavender essential oil has various benefits and is suitable for all hair types. These are some of its actions on hair and scalp: 

  • True lavender essential oil soothes the scalp.

Irritation and discomfort of the scalp can be reduced thanks to the soothing properties of true lavender essential oil. Its sedative and calming actions complement these properties and ensure the well-being of the scalp. The linalool and linalyl acetate that compose it are indeed able to inhibit certain nociceptors, receptors responsible for the transmission of pain in the body. Itching is thus attenuated, which also limits the desquamation of the scalp and the formation of dandruff. In addition, the antimicrobial properties of true lavender oil for the scalp allow it to fight against bacteria and fungi, thus sanitizing it.

  • It acts against certain parasites.

The presence of linalool and terpinene-4-ol in True Lavender essential oil makes it an effective repellent against scalp and hair parasites, such as lice. Indeed, these molecules inhibit acetylcholinesterase, an enzyme found in these parasites and leading to the degradation of their neurotransmitter acetylcholine. This mechanism is at the origin of the neurotoxicity of the essential oil of true lavender for the lice. To fight against them, apply a drop of essential oil pure or diluted in a vegetable oil behind each ear and massage. This treatment can be done in preventive or corrective action.

  • Lavender oil may help with hair growth.

Indeed, a study has shown that its use in synergy with essential oils of thyme linalol, rosemary, and Atlas cedar would help to mitigate alopecia. A comparison of hair growth was conducted over 12 weeks between two groups of individuals suffering from alopecia: one applied the essential oil blend to the scalp and the other used a placebo. The results showed that hair growth was significantly greater in the group using the essential oil mixture that also contained lavender oil. However, the exact mechanism behind this hair growth has not been elucidated.

  • It has purifying properties.

True lavender oil for hair and scalp with an oily tendency is perfectly suited. The active ingredients in its composition (mainly linalool and linalyl acetate) give it an absorbing action, thus limiting the negative effects of hyperseborrhea. The scalp, as well as the hair, appear less fatty. A decrease in sebum levels has been observed when using a combination of lavender, tea tree and eucalyptus essential oils.

It is also suggested that true lavender essential oil would promote hair growth by stimulating blood microcirculation, but these properties remain controversial.

Precautions To Take Regarding the Use of True Lavender Essential Oil.

True lavender oil is suitable for all types of hair and scalp and is very mild. It is one of the most recognized essential oils in aromatherapy: it can be used pure and does not cause skin irritation. Nevertheless, its use is not recommended for pregnant and breast-feeding women, and for young children. To avoid any risk of overdose, it is advised to people with sensitive skin to dilute it in a vegetable oil.

It is also important to note that true lavender essential oil contains potentially allergenic biochemical compounds, such as geraniol, linalool, coumarin and limonene. It is therefore recommended that a tolerance test be performed before incorporating it into a hair care product.

To test true lavender essential oil, apply two drops to the hollow of your elbow and wait at least 24 hours. If no adverse reaction is observed, it can be used on the scalp or skin.
