Dermatology
Some essential oils are recognised for their moisturising, softening, nourishing, astringent, firming, and anti-acne properties. However, caution is advised, applying pure essential oil directly to the skin is not recommended. It is always better to dilute it in a vegetable oil.
Dosage recommendations vary depending on the essential oils, but generally, it is appropriate to mix 30 drops of essential oil into 50 ml of vegetable oil. The blend can be applied to all parts of the body, avoiding mucous membranes and the eye contour. In local application, this mixture can alleviate various skin problems (acne, redness, dryness...) as well as insect bites, knocks, bruises...
Caution! Some essential oils are photosensitising and it is advised not to expose oneself to the sun for at least 4 hours after application. Others can be allergenic. Always perform a preliminary test in the crook of your elbow.
Here is a list of essential oils containing allergenic molecules in significant quantities: aneth, angelica, bergamot, bergaptene-free bergamot, cajeput, cinnamon (bark), lemon, clove, coriander seed, rose geranium, fragrant inula, bay laurel, lemongrass, green mandarin, lemon balm, lemon myrtle, sweet orange, compact oregano, Spanish oregano, palmarosa, grapefruit, turpentine, exotic verbena, fragrant verbena.
Haircare
Whether it's to combat scalp dandruff, hair loss, excess sebum, or even the dehydration of hair fibres, it can be relevant to incorporate a few drops of a carefully selected essential oil into your shampoo and/or hair mask, depending on your specific issue.
For instance, to purify the scalp and eliminate dandruff, tea tree essential oil, as well as lavender essential oil and palmarosa essential oil, are recommended.
Regarding oily hair, the ones from Rosmarinus officinalis with cineole, fromYlang-Ylang or even fromSweet Orange Citrus sinensis are more suitable.
To strengthen one's hair and combat premature hair loss, it is advisable to rely on essential oils that stimulate micro-circulation, such as grapefruit essential oil (Citrus paradisii) or Atlas cedar oil (Cedrus atlantica).
