Castor Oil Side Effects on Hair and Scalp

Most people use castor oil to help their hair grow faster, longer, and thicker. It restores moisture to both the hair and the scalp when used in this manner. Many of the side effects of castor oil relate to issues with ingesting it, something we do not recommend. That doesn’t mean that you’re completely in the clear with using it on your hair and scalp though.

When it comes to your hair, the worst thing that could happen is that you won’t see a noticeable difference in the quality of your strands. Perhaps your hair is already healthy and properly moisturized. This may explain why it doesn’t do much for you.

Applying it to your scalp could be a different story though. Any kind of topical application could result in skin irritation. It may look like a red spot with patchiness, an intense itch, or a prevalent rash. It will resemble an allergic reaction in the area where the castor oil was applied.

It may be difficult to see these issues on the scalp underneath all of your hair. If you feel any pain or scabs through your hair after a treatment, discontinue your use of the oil immediately.

Side Effects on Skin

Castor oil is a natural product that can help to restore moisture to dry and damaged skin. It’s a key ingredient in many homemade lotion recipes, but it can also be applied on its own. You can use it to wash your face, calm irritated skin, and more.

Much like the castor oil side effects for your scalp, a topical application can cause some potential side effects for skin in other areas. First, you might develop sensitivity in the spot where castor oil touched the skin. It may present with redness, itchiness, or general irritation.

In more extreme instances, you may develop a rash that could signal an allergic reaction. In this case, you may want to make an appointment to see your doctor immediately.

Side Effects on Baby

Parents struggling to find natural products to take care of their baby’s skin may turn to castor oil as a solution. As a general rule, a baby is more at risk for issues with their skin than an adult. This is the result of a thinner epidermis that has yet to fully develop.

Because their skin is so sensitive and is still in the process of developing, you need to proceed with any remedy for babies with caution – castor oil included! Be aware of any potential side effects with your baby before you try our DIY baby balm to nourish their dry skin.

Similar to an adult, babies can develop a sensitivity to the ingredients and chemicals naturally found in castor oil like ricinoleic acid. If it seems like your baby finds their skin overly sensitive following an application, you may want to abandon using it. It could also lead to redness, itching, or a widespread rash if they are allergic to or extremely sensitive to the oil.

Castor Oil Side Effects During Pregnancy

You can use castor oil for a wide variety of applications during your pregnancy. Expectant mothers may use it on their skin to help stretch makes fade away or to soothe their dry skin. With this in mind, the castor oil side effects will be the same as they are for skin application in general.

Many people do attempt to ingest castor oil to induce labor but this is not recommended. It is an extremely powerful laxative and could potentially be fatal for you or the baby. The side effects are too great to risk ingesting castor oil, especially if you happen to be pregnant.

Castor Oil Side Effects on Eyelashes

One of the most prominent uses of castor oil is to help thicken and extend the eyelashes. Particularly when using an ingredient on such a sensitive part of the body, what can you expect?

While the list of benefits for using castor oil on your eyelashes is far longer than the risks, you should know that there are a few side effects. They may not occur with every individual, much as with any specific side effect. There are three major effects possible when you use this ingredient to help thicken your eyelashes:

  • Excess drying around the eyes
  • Increased sensitivity around the eyes
  • Can impact vision over a long period of time by drying out the eyes

You can minimize these side effects by using a small amount of the ingredient around your eyes as a tester. Try it for a few days but always take caution not to put it directly in your eye. Your beauty routine should never include putting anything in your eye. You should only use a few drops on a clean mascara wand to apply to the eyelashes.

I highly recommend purchasing only high-quality castor oils for use on these sensitive parts of the body. My personal favorite is the Foxbrim organic castor oil, but anything you use on the eyes should be hexane-free, organic, and cold-pressed to ensure that it has the maximum properties you would want.

Final Thoughts

In general, there aren’t many side effects that you should be concerned with as long as you aren’t ingesting it may lead to constipation. Also, always test your oil before taking a bath as it may lead to castor oil bath side effects

Many of the side effects result in skin irritation or allergies, which should be fairly obvious if they present themselves. Always test castor oil on the palm of your hand and decide for yourself. However, make sure that you’re taking care of castor oil detox side effects while including it in your diet.
