Using castor oil for hair is a natural and easy way to revitalize your locks and protect your hair from damage when used properly. Castor oil is a very effective remedy for your hair health, and it is something that can be used every day. However, most regular users claim that using it 2-3 times per week is more than enough to see measurable results.
Castor oil is the oil extracted from castor seeds, which come from the castor oil plant, scientifically known as Ricinus communis. These seeds contain a high concentration of essential oil, ranging from 40-60% of the total volume. The oil is colorless, but it has a very clean flavor and odor and is considered a triglyceride. The majority of the benefits that castor oil can provide comes from its active ingredient, ricinoleic acid, along with various other volatile compounds and antioxidants. 
What Type of Castor Oil Should You Use?
If you want to use castor oil on your hair, you want to be sure you choose the right variety.
- Castor oil blends: Some people like to make their own castor oil hair treatments with a combination of castor oil and other hair-healthy oils, such as jojoba oil or coconut oil.
- Cold-pressed castor oil: It is always best to use organic or cold-pressed castor oil, as this will have more nutrients and fewer additives or chemicals.
- Jamaican black castor oil: Many frequent users claim that Jamaican black castor oil is particularly effective, as it isn’t as thick or viscous as other varieties, which makes it easier to spread through the hair. 
- Hydrogenated castor oil: People also use this variety of castor oil. However, this is best avoided as hydrogenated castor oil often comes in the form of hard wax, and it will harden when exposed to water.
