Oils were once regarded as things we would never want to put on hair. Why would we want to add even more oil to greasy roots? Innovative oil-based shampoos have made us reconsider our stance. They prove that the right oils can actually be lightweight and help rebalance the scalp and nourish hair. Argan oil, olive oil and coconut oil are some of the most popular hair care oils. Castor oil for hair also belongs on everyone’s radar, especially those who want to grow longer hair.
Castor oil may be relatively new to a lot of people, but WEN founder Chaz Dean explains that it has actually been widely used in beauty products for years. The reason it is such a popular ingredient is because it’s rich in proteins, minerals and vitamin E. What also makes castor oil for hair so great is that it has anti-inflammatory and antibacterial properties. This makes it able to fight itchy scalps and dandruff, condition dry strands and reduce split ends. Castor oil even helps boost shine.
Because it balances the scalp, castor oil can also help hair grow longer. CURLS founder and CEO Mahisha Dellinger explains that castor oil also carries ricinoleic acid and omega-6 essential fatty acids, which accelerate blood circulation to the scalp and help increase hair growth.
It can be tempting to slather on the castor oil after hearing about all of its benefits, but Dean states that it should be used on all hair types sparingly. A little bit of castor oil for hair goes a long way because the oil can sometimes be heavy. Because of this, castor oil is best for those who have dry, thinning or damaged locks.
Castor oil for hair can be purchased as a pure oil or it can be found as an ingredient in hair products, including shampoos, conditioners and even styling products. Dellinger explains that pure castor oil can be applied to the scalp to prevent dandruff and increase hair growth. It can also be used on the ends of hair to treat and prevent split ends.
For those who prefer to incorporate the oil into the hair products they already own, Dean recommends mixing a small amount with conditioner, a hair serum or a styling cream. And for those who don’t feel like mixing their own products, there are lots of premixed ones that feature nourishing castor oil. Try some of the products above.
