What is castor oil?
Also known ascastor oil, castor oil is a vegetable oil derived from the cold pressing of seeds from the common castor oil plant, a shrub of tropical origin from the Euphorbiaceae family. Originally, castor seeds are toxic due to the presence of an enzyme, ricin. Fortunately, the extraction of castor oil requires high levels of heat, which can neutralise the ricin and make castor oil safe for cosmetic use. Castor oil has a dense and clear oily texture. It is pale yellow in colour, or even colourless. Its discreet scent is sweet and pleasant.
Castor oil is primarily composed ofricinoleic acid (ranging from 83% to 88%). It also contains oleic acid (omega-9), linoleic acid (omega-6), palmitic acid, and stearic acid. Thericinoleic acid has antimicrobial properties, making it effective against certain skin conditions such asacne ; in medicine, it is recommended for treating certain gum diseases. When regularly applied to the hair and roots, castor oil purifies the scalp and combats hair fibre loss.
Thus, this oil can provide benefits to the skin, hair, beards of varying thickness, as well as to nails and cuticles.
The effects of castor oil on nails.
Nails are daily subjected to numerous external aggressions, such as manual labour, hand washing, semi-permanent varnishes, etc. Over time, their condition can deteriorate, becoming soft and brittle. Just like skin and hair, it is also essential to take care of them. Castor oil can provide the following benefits to your nails:
Combat against brittle nails and prevent fungi thanks to the presence of undecylenic acid, a powerful fungicide present in its composition. Its application will protect the nails and cuticles from infections and fungal diseases;
Hydrating the cuticles in order to provide them with a certain flexibility and enable them to be effective in preserving the matrix of our nails. The fatty acids present in castor oil will thus hydrate and nourish the cuticles well;
Protecting the nails from external aggressions and free radicals thanks to the vitamin E.
How can one best benefit from the effects of castor oil on the nails?
Firstly, castor oil should be applied regularly. Its benefits on the nails will be visible after one to four weeks of use. The nails will be healthier, better hydrated and stronger.
Castor oil can be applied either directly with the finger, or like a nail varnish using an applicator brush. To allow it to penetrate, the nails should be gently massaged in circular motions.
For nails in poor condition, it is possible to perform an oil bath approximately once or twice a week. Simply pour castor oil into a bowl in which you immerse your nails for about fifteen minutes. Afterwards, gently massage the nails before rinsing and drying them.
Note : During the treatment of damaged nails, it is advisable to let them "rest" by spacing out manicure sessions.
