Castor oil benefits for hair 

Hair growth  

One of the major castor oil benefits for hair is that it helps in hair growth. Since it is loaded with vitamin E and other fatty acids, it strengthens hair roots and stimulates blood circulation needed to grow hair, and regulates the hair growth cycle. It also acts as a shield against pollution and free radicals that threaten to damage hair. 


Castor oil also has ricinoleic acid which is anti-inflammatory. It lessens irritation on the scalp that may inhibit healthy hair growth. And – you’ve guessed it – it also soothes the consequences of dandruff. 

Shiny hair  

Packed with nourishing and moisture-locking properties, castor oil adds an extra dash of shine to the hair. It also conditions dry and damaged hair. The antioxidants in it even stimulate keratin production in the hair, making it stronger. 

Healthier hair growth 

Okay, we’ve already established that castor oil is a super ingredient of sorts. So, don’t be surprised if we continue to list castor oil benefits for hair. It not only helps hair growth but also makes sure that it is healthy in the most unconventional way. It dilates blood vessels which leads to better blood flow which supplies oxygen and essential nutrients to the hair roots. So, say goodbye to split ends and brittle strands. 

Thicker hair 

Why is castor oil a second favourite after the popular coconut oil? It is because it is said to increase hair growth by about four to five times the normal rate, while also encouraging your hair to grow thicker. This is why you must have heard of castor oil as a home remedy for thin eyelashes. There are also decades-old testimonies that it seemingly grows back bald patches. 

Slows down greying 

Castor oil is also an excellent treatment for preventing premature greying. Applying small amounts of castor oil to your hair can help retain its colour for relatively longer, keeping it from turning grey too early. 

Gets rid of dandruff 

Castor oil is a natural elixir for your mane. Since it is antifungal and antibacterial, it kills the fungus that causes dandruff and other infections, which reduces flakes and calms itching and irritation. Plus, it maintains the pH balance of your scalp so that you don’t get dandruff in the first place.
