Can Castor Oil Help with Hair Loss?

Hair loss is a common concern for many people within the UK. Factors including stress, hormonal imbalances, age, and genetics all playing a key role. While medical treatments like minoxidil and finasteride are widely used (particularly for male pattern baldness), many people are also exploring natural remedies to support hair growth. One particular remedy that has become quite popular is the use of castor oil.

But can castor oil help with hair loss? And how should you use it?

What Is Castor Oil?

Castor oil is a thick vegetable oil derived from the seeds of the Ricinus communis plant, and has been used for centuries in traditional medicine, skincare, and hair care. It is a nutrient rich oil, especially in ricinoleic acid, a type of omega-9 fatty acid known for its anti-inflammatory and antimicrobial properties. This makes it a potentially useful oil for promoting scalp health, a key factor in reducing hair shedding and supporting regrowth.

How Might Castor Oil Help with Hair Loss?

While there is limited clinical research directly linking castor oil to increased hair growth, many people have reported castor oil’s benefits; some stating that using castor oil once a month helped their hair grow to three times their normal rate. While there is no clinical evident to support this, many have theorised how exactly castor oil may benefit hair regrowth and hair health.

Improved Scalp Circulation

Ricinoleic acid in castor oil may help improve blood circulation to the scalp. This could ensure that hair follicles receive the nutrients and oxygen needed to grow stronger, healthier hair.

Anti-Inflammatory Properties

Conditions like dandruff, seborrheic dermatitis, or other forms of scalp irritation can cause hair to thin or fall out. Castor oil’s natural anti-inflammatory properties may help calm the scalp and reduce hair loss linked to these conditions.

Moisture and Protection

Castor oil is an excellent emollient. It locks in moisture and coats the hair shaft, which can prevent breakage and split ends. Healthier, hydrated hair is less likely to fall out prematurely.

Antimicrobial Effects

The oil’s antifungal and antibacterial effects may help prevent scalp infections, another potential contributor to hair thinning.

How to Use Castor Oil for Hair

If you are looking to try castor oil for hair health, it is important to first know which type to use. Cold-pressed, pure castor oil is extracted with extreme pressure similar to a machine used for juicing. Black castor oil uses castor oil seed which are roasted, then heated before extraction. Jamaican castor oil is created from castor oil seeds which are roasted, crushed, ground, and boiled before they are pressed. For hair use it is recommended to use either pure castor oil or Jamaican castor oil though which you use is up to you.

Precautions and Side Effects

Castor oil is safe to use on the scalp, and in hair, and has many anti-inflammatory and antibacterial properties which may benefit your skin. However, as with any new product, it is important to use a patch test before use as castor oil may irritate parts of the body if used incorrectly. It is important to note that castor oil should not be used on irritated skin (active rash or broken skin). If castor oil should get into your eye(s), this may cause irritation but can be washed out using warm water.
