Research source} Castor oil is derived from the bean of the castor plant, and it's great for treating an irritated scalp and dry hair. But it can also be tricky to wash out and remove all of the oily residue when you’re finished. Luckily, you can use shampoo to remove castor oil from your hair so you're left with shiny, healthy strands.

Shampoo your hair twice if there’s still some excess oil. Sometimes, 1 shampoo may not be enough to get rid of the oily buildup and residue that castor oil can leave behind. If you aren’t satisfied after 1 wash, no problem. Shampoo your hair again to see if that helps.^{[4]

Treat irritated scalp, excess oil, dandruff, and dry hair with castor oil. Although castor oil is often touted as a hair growth product, the scientific evidence doesn’t seem to fully support the idea.^{[8]

Choose Jamaican black castor oil for thick hair and cold-pressed for thin hair. Jamaican black castor oil is boiled with ash, which gives it its distinctive dark color and lovely roasted scent. It’s also a little thicker, making it a better option if you have naturally thick or curly hair. Cold-pressed castor oil is pure oil pressed from the castor bean, and it’s a little thinner than Jamaican black castor oil. Use it if you have thinner hair so you don’t add extra weight or oily residue to your hair.^{[10]

- There are other castor oil products that have added colors and scents you can choose from if you prefer.

Test a tiny amount of the oil on your inner arm for 24 hours. Castor oil can cause an adverse or allergic reaction in some people, especially if you’re using it for the first time. Take a dime-sized amount of the oil and rub it on a small spot on your inner arm. Leave the oil in for a full day to make sure you don’t have a negative reaction.^{[11]

Dip your fingers into the oil and gently massage it into your scalp. While your hair is still dry, open up your container of castor oil and coat your fingers in the oil. Work in sections and gently massage the oil into your scalp. Continue applying the oil until all of your scalp is nicely coated.^{[12]

- Applying the oil to dry hair can make it easier for you to distribute it evenly.
- Take your time and apply the oil all over your scalp.
5
Apply castor oil as a pre-shampoo treatment 1-2 times a week. Spread the oil over your scalp, comb it through the ends of your hair, and leave it in for at least an hour (or sit under a hair steamer for 30 minutes). Then, wash it out of your hair with shampoo. Use the treatments only once or twice a week to hydrate your hair and scalp without too much oily buildup in your hair.^{[13]

- Shampoo your hair twice to remove the oil if necessary.
6
Leave the castor oil in your hair overnight for deeper conditioning. Spread the oil all through your scalp and hair and then slip on a shower cap to keep from getting it onto your pillow. Leave the oil in while you sleep and then wash it out the next day for an even deeper hydrating treatment.^{[14]

- If you’re leaving the oil in overnight, you only need to do it about once a week. Any more than that and your hair could become too oily.

Hair oils are great for shine and manageability. If you apply them to wet hair and blow-dry your hair, you'll get great added shine. You can also use it on dry hair to add some luster and help with flyaways and frizziness.
