Those who struggle with hair issues are most likely familiar with castor oil and its benefits. After all, everyone recommends it, even the experts agree that castor oil can do wonders for hair. And they’re right! Topical use of castor oil can improve scalp condition and hair quality on all fronts — from strengthening strands, promoting hair growth, stimulating the scalp, castor oil has it all. TBH, there’s always something castor oil can help with, and thinning hair is not an exception.

Castor oil for hair growth

Thanks to the nutrients it contains, castor oil can defend the hair follicle from outside cellular and tissue invaders that destroy them, creating a healthy environment for hair to grow thicker and stronger. Castor oil also acts as an anti-inflammatory agent, protecting the hair follicles by preventing their inflammation. Last but not least, castor oil is rich in omega-6 fatty acids and can boost blood circulation in the scalp, allowing more nutrients to reach hair follicles.

Is it safe?

Although it’s generally considered safe, applying castor oil to the scalp may lead to skin irritation, inflammation, and dryness. So start slow and try not to overdo it. You may as well do a patch test — rub a small amount of castor oil on your elbow area to test for any allergic reaction before use. Also, avoid contact with the eyes because it may cause irritations. And yes, pure castor oil can be applied to all hair types, including thin and fragile.

How to apply castor oil for hair growth?

You can directly apply the pure castor oil to the scalp. Bear in mind that it’s very slippery, so it will be challenging to make it all stay on your head.

Apply by warming up a small amount of oil in your hands and massaging it into the scalp. Then apply castor oil to the rest of your hair until it’s all moist — you can use an applicator brush to ensure even coverage. Put the shower cap on and leave it for at least 1 hour to give oil enough time to penetrate the scalp and reach hair follicles. Finally, wash as usual with shampoo and conditioner. 

How to pick the best castor oil for hair growth?

There are a few things to consider, such as purity level or concentration of hexane, to make sure you get the best castor oil for hair growth. We made sure that the products we’ve picked have 100% purity, which means they are not mixed with any other oil or artificial ingredients that could diminish the hair growth effects. The best castor oils for hair growth should also be hexane-free. Hexane is a chemical solvent used to extract oil from plant seeds to make the process easier. This solvent, in most cases, causes impurities to remain in the oil, affecting the quality of castor oil.

It turns out these are the best castor oils for hair growth.
