This small, deciduous tree grows well throughout Northern Europe, but excels in the Mediterranean where it is widely cultivated. Hazelnut trees can still be found growing wild in British hedgerows and woodland, bearing long, yellow catkins around March time.
The oil, which accounts for approximately 40% of the nuts weight, is extracted from the kernel by cold pressing. The oil is then left for several days to let the sediment settle before filtering.
The quality and ‘grading’ of the oil will vary according to its purpose – the cosmetic industry will often refine Hazelnut Oil Hair before adding to their own products, while the food industry tends to roast the nuts prior to extraction in order to enhance the oils flavour. Similarly, the quality of the oil will depend upon the quality of the nuts from which it is extracted. For the above reasons, it is also commendable to buy Carrier Oils from reputable suppliers who specialise in Aromatherapy products.
Main therapeutic uses
Hazelnut Oil is believed to be very nourishing for the skin as it is rich in vitamins (A, B and E), minerals and proteins. As it is easily absorbed and softens the skin, this oil is a favourite ingredient in many beauty products, particularly face, hand and body creams. Hazelnut Oil can also be found in many sun protection and after-sun lotions.

Do not use on clients with a nut allergy. Carry out a patch test if the client has a history of allergic reactions. Hazelnut oil is good for greasy skin as it is readily absorbed. The oil is amber/yellow in colour. Its Latin name means ‘little helmet’ which alludes to the shape of the nut.
