Castor oil benefits for hair are linked to its remarkable moisturizing properties. Its unique combination of fatty acids makes it one of the most replenishing oils on the market. This is also what contributes to its other health applications. 

It can be applied to the hair with other ingredients as a hair mask. You can also apply it by itself for full potency. The castor oil locks those fatty acids into the hair’s cuticle. 

The high concentration of omega essential fatty acids encourages the repair of mistreated locks. They leave a shiny healthy-looking head of hair.

Sealed and moisturized cuticles protect your hair from the damage caused by styling tools. The antimicrobial properties of castor oil also help prevent dandruff and other scalp irritations. It can also be used for psoriasis and may even help in cases of skin cancer.

The main component that sets castor oil apart is the inclusion of the very rare ricinoleic fatty acid. Castor oil seeds are one of the only natural sources of this fatty acid complex. It’s good for your entire body but, there’s clinical evidence that it’s especially effective for gut health. 

The natural properties of castor oil help hair health in many ways. It moisturizes the scalp, seals the hairs cuticle, and replenishes nutrients to the hair shaft.

Castor Oil for Hair Guide Part V: Castor Oil for Hair Growth & Hair Loss – Does it Work?

Castor oil will treat some forms of hair loss, but certainly increases circulation which is a key factor in increasing hair growth. 

Hair loss due to breakage or damage hair is easily cured by castor oil. It also cures piedra, ringworm, and folliculitis hair loss conditions.

The omega 6 fatty acids, vitamin E, and proteins will revitalize hair and moisturize each individual hair shaft.

Circulation is a key factor for hair growth. Thanks to the high concentration of ricinoleic acid the oil is great for increasing circulation.

Castor oil massaged into the scalp will stimulate blood flow, expediting the delivery of nutrients to hair follicles. That means hair will become thicker and healthier. 

It will be able to grow longer without getting frail or breaking. Castor oil is also known to help those struggling with postpartum hair loss or hair loss caused due to increased stress.

For those suffering from genetic hair loss such as pattern baldness (like alopecia areata), castor oil may have some benefit. Whether it grows lost hair or not is up for debate.

It is unlikely castor oil will stimulate new hair growth in dormant hair follicles. It may help purge scalp DHT as it is antifungal. However, most evidence that castor oil can prevent further hair loss is anecdotal.

Some that have experimented with castor oil and Rogaine have reported much better results than using Rogaine alone. 

Perhaps, this is because the essential fatty acids accelerate blood circulation. In theory, this helps the follicles absorb the minoxidil.

Castor Oil for Hair Guide Part VI: Castor Oil Hair Treatment – 5 Easy Steps

Do this treatment once a week to keep your hair healthy, shiny, and strong.

  1. Mix the three oils in a dropper bottle. Shake vigorously.
  2. Part your hair down the middle. For a thorough treatment, section your hair into 4-5 sections. 
  3. One section at a time, use the dropper to apply the oil to your scalp and roots. Work your way down the length of your hair.
  4. Massage the oil mixture into your entire scalp and work through the hair. Once the oil is applied to all sections, massage your scalp for about 5 minutes to increase blood circulation.
  5. Pin each section up on the top of your head. Place the shower cap over all of your hair. Leave it in place for 15-20 minutes. Then thoroughly wash with sulfate-free shampoo and conditioner as normal.

Recommended Application Tools

  • An old t-shirt 
  • A dropper for the oil
  • Sectioning clips
  • Rubber gloves 
  • A shower cap 
  • A wide-toothed comb or applicator brush
  • A large towel

Recommended Formula

We recommend the following natural oil mix: castor oil, jojoba oil, and coconut oil. The combination of oils will give you the best results.

You’ll want to use 3 times as much castor oil as the other two oils. 

Start with 3 Tablespoons of Castor Oil, 1 Tablespoon of Jojoba Oil, and 1 Tablespoon of Coconut Oil. 

Depending on the length and thickness of your hair, this will give you about 5 castor oil hair treatments.
