The Benefits of Jojoba Oil on Hair

Dry hair results from a lack of sebum production in the scalp. This can be caused by the use of an aggressive treatment that distorts the structure of the hair fiber or by a decrease in cell activity with age. However, this lack of sebum can be compensated for by providing essential fatty acids. Jojoba oil, which is mainly composed of omega-9 fatty acids (approximately 70% gadoleic acid), can provide this supply. It can be used in the form of a hair mask or oil bath to be spread on the scalp and all the lengths. Moisturizing the hair also gives it suppleness and shine. In the case of curly hair, jojoba oil helps to define curls, while strengthening the elasticity of hair fibers. This makes the hair easy to style and detangle.  

Unlike dry hair, oily hair produces an excessive amount of sebum. This can cause hair to become sticky, shiny and flat. Oily dandruff is also common. In fact, it is the result of an inflammatory reaction following an accumulation of pollution and impurities on the scalp. To cleanse this area, opt for a massage with jojoba oil before each shampoo. At the base of the hair, apply the equivalent of a tablespoon of jojoba oil and massage the scalp. You can leave this oil in for a few minutes to an hour before shampooing.

In addition to its effect on the appearance of hair, sebum is part of the composition of the protective film of hair, namely the hydrolipidic film. As its name suggests, this protective layer protects the hair fibers from external aggressions, mainly pollution. The presence of vitamin E and minerals such as zinc in its composition also makes jojoba oil a protective agent against UV rays. UV rays can weaken the hair by attacking keratin. As a reminder, keratin is a protein that makes up hair fibers and ensures their cohesion. It thus prevents hair from breaking. In addition, UV rays are also responsible for the multiplication of free radicals that cause dullness and grayish hair color. To benefit from this protective effect, we recommend applying jojoba oil to the lengths before any exposure to the sun.
