What is castor oil and what is it for?

Castor oil is a vegetable oil extracted from the castor bean seed, a plant found in several parts of and the world.

The seeds themselves are highly poisonous. They have the toxic protein called ricin which, even in small doses, can lead to death. However, during the extraction of castor oil this toxic component is eliminated, and this ensures the safe and healthy use of castor oil.

This is because, castor seeds are essentially formed by oil, reaching 49% of its total. Among its main components are fatty acids, including omega 6 and 9, as well as mineral salts and vitamin E.

Because of its composition, castor oil is generally used in three ways: in the chemical industry, in the cosmetics and pharmaceutical sector.


Industrially, castor oil is used in the manufacture of paints, plastics, glues and lubricants. But its great fame is with the cosmetic and medicinal use.

One of the most well-known medicinal uses of castor oil is as a natural laxative. However, it should not be used often, as prolonged use can bring health problems.

For this reason, the oral use of pure castor oil should preferably be done with a doctor.

In the cosmetics segment, castor oil is found in several beauty products, especially those that propose to moisturize hair and skin. You will often find castor oil under the name “Castor oil”, which is its English name.

What are the benefits of castor oil for hair?

One of the main actions of castor oil is to moisturize the hair strands and clean the scalp. But the benefits for the wires go beyond. Check out what are the effects of castor oil on hair:

    • Restores, hydrates and stimulates growth. Thanks to omega 6 and omega 9, castor oil can give more volume and help with hair growth. This is because fatty acids stimulate the scalp and the follicles where the strands are born. In addition, they seal cuticles, eliminating frizz and dryness
    • Combating dandruff: Castor oil also has antifungal properties, which cleanse the scalp and, thus, acts to combat dandruff.
    • Reduces oiliness: Widely used in shampoo compositions, castor oil helps to reduce excessive oiliness on the scalp.


Can I sleep with castor oil in my hair?

Many people choose to hydrate their hair at night. For this, the oil is passed on the wires, the hair is wrapped in a cap and the product is removed the next day.

However, you should not sleep with castor oil in your hair. Experts recommend that when you pass the pure castor oil on the strands you should remove it within 10 minutes – not to exceed two hours.



Did you know that castor oil is one of the most effective to perform hair moistening?

Humidification is a deep hydration that, in addition to nourishing, helps to recover damaged hair and split ends.

The use of castor oil as a humectant can be done on all types of hair.

The fact is that the prolonged use of castor oil in the hair can generate an effect contrary to that of hydration and promote breakage and hair loss.

To prevent undesirable effects, it is ideal that you avoid using pure castor oil in the strands. The most recommended is that you mix it with a cosmetic before applying it to the hair. For example, you can add a tablespoon of the oil to a 200 ml pot of conditioner.

Castor oil for skin and nails: how and when to use?

In addition to being beneficial for hair and scalp, castor oil is also widely used in hydration and skin treatments, in addition to strengthening nails.

However, it is essential that you have a dermatologist follow up before starting any treatment with castor oil.

This is because, as we will see later in this article, castor oil is not free to cause side effects. In addition, it is worth remembering that each person has a skin type with different needs and characteristics.


Experts also warn that the use of pure castor oil on the skin is not recommended. The safest is to mix it with a moisturizer. For this, you can add one tablespoon of castor oil for each 200ml of product.

For you to understand all the power that castor oil has on the skin and nails, here are some tips on how and when to use this vegetable oil:

  • To combat acne and greasiness: Castor oil promotes skin hydration while acting as an astringent, preventing bacterial proliferation, which is one of the causes of acne. So it is very suitable for those with oily skin.
  • To moisturize: If you have very dry skin, castor oil can be used as a natural moisturizer as its properties prevent water loss through the skin.
  • To heal: Castor oil also has a healing action due to the presence of vitamin E. Therefore, it ends up being widely used by those who have stretch marks. In addition, castor oil is an ideal after-sun cosmetic to treat sunburn.
  • Nails: Castor oil can contribute to the hydration of the cuticles, which also helps in strengthening brittle nails. In that case, it is possible to apply the pure castor oil to the nails and leave for a maximum of one hour.

Is it safe to use castor oil on eyebrows, eyelashes and beards?

Just as castor oil is good for hair, it is also suitable for eyebrows, eyelashes and beards. In this case, it is known to thicken the strands of these regions.

However, you need to take some extra precautions. If used on eyebrows and eyelashes, you need to avoid the eye area.

As it is not yet known what all the effects of castor oil are, dermatologists emphasize that you should not apply it to mucous membranes, such as the mouth, eyes and ears.


Therefore, it is recommended that you apply castor oil to the eyebrow and eyelashes with the help of a brush specifically for these regions, such as those used to apply mascara, for example.

In both cases, however, it is essential to have the follow-up and prior evaluation of a dermatologist to carry out a correct and effective application.

In the case of beards, castor oil acts in the same way as in hair and can be used to stimulate the growth of thicker and stronger hair.

What are the side effects and contraindications of castor oil?

As we have already mentioned, castor oil is not free from causing health problems and discomfort. Especially when it comes to its pure formula, whether used on hair and skin is ingested, the fact is that castor oil can indeed cause side effects. Here are the main ones:

The main advantage is, certainly, the high hydrating power of this oil, which is used for hair, eyebrows, eyelashes and beards, as well as for skin and nails.

In addition, because it contains fatty acids in its composition, castor oil fights fungi and bacteria that prevent hair growth. So it is widely used to stimulate hair growth.

Rich in linoleic acid, vitamin E and minerals, castor oil also has great cleaning power, which helps to reduce oiliness.


Another advantage is that, today, it is possible to find a huge variety of products such as shampoo, conditioner and hydration masks made from castor oil. Not to mention that oil in its pure form also has a great laxative effect.

On the other hand, not all people can and should use castor oil.

You will find castor oil costing between R $ 16 and R $ 300.

Still, it is not an expensive product, neither in the cosmetic version nor in pure oil. Therefore, you will find castor oil costing between R $ 16 and R $ 300.

However, it is more worthwhile to buy castor oil over the internet, in stores. That way, you get the product from the comfort of home and you will still have more product options and brands to choose from.


Purchasing Criteria: What You Should Consider Before Buying Castor Oil

As we have seen, some care is needed before starting to use castor oil, from the monitoring of a specialist to the form of use.

Likewise, attention is needed when buying castor oil, both to ensure the product’s efficiency and a good investment of your money. Therefore, we have listed below the main criteria that you must analyze before buying castor oil.

  • Goal
  • Cosmetic or fresh
  • Unit or kit
  • Amount

In the following, we will explain how you should analyze each of these factors.


is: Why do you need this product? Your answer will certainly define the purpose for which you intend to use castor oil.

As we have seen, castor oil can be used for different purposes, and in different regions of the body.

In general, the main purpose of castor oil is to moisturize. But you can also use it to fight oiliness, help with healing and stimulate hair growth.

So, in general, you will have to decide whether to use castor oil as a natural laxative; for hair and threads; or for the skin and nails.

Cosmetic or fresh

Once the purpose is defined, you must consider which way you will use castor oil: in the fresh version or in cosmetics.

In the pure version, castor oil is usually found in small bottles. It can either be ingested for laxative effect or mixed with other cosmetics to be used on hair, skin and nails.

Remembering that to use the safe dosage for your health you must consult a doctor or dermatologist.


In the cosmetic version, castor oil is found as a basis for the composition of moisturizing creams, moisturizing oils, nutrition masks, growth tonics, shampoos, finishing ointments and conditioners.

If you choose the cosmetic, take into account that, depending on the type, it can come together with other substances that are also beneficial, for example, coconut oil, argan oil, keratin, other vitamins and etc.

Unit or kit

Regardless of whether you buy the cosmetic already enriched with castor oil or pure oil, take into account what will be most profitable and economical for you: buy the unit or a kit.

In general, the kit comes with two or more products and ends up being more advantageous in relation to the final price.

However, if this is your first time to use castor oil, we recommend that you opt for the product unit.

That is, it is worth experimenting and seeing how the castor oil reacts in your hair or skin. If the result is positive, then yes, it is worth investing in a kit or more products enriched with castor oil.


Finally, note the quantity of the product you will buy. This criterion will vary greatly depending on the type of castor oil you choose.

For example, if you opt for fresh oil, you will find bottles that have between 5ml and 500ml.

But if you prefer to buy products like shampoo and conditioner, for example, the quantity varies more and will impact the final price.
