But anecdotal evidence aside, does using castor oil for hair growth actually work? WH tapped up a trichologist, hair stylist and two afro hair experts to find out.
What is castor oil?
A natural elixir, castor oil is extracted from the seeds of the castor plant and one of the key reasons castor oil has become a trending hair growth solution is its unique composition. It is packed with essential nutrients, including vitamin E, proteins, omega-6 fatty acids, and minerals such as magnesium and calcium. These components are thought to work synergistically to nourish the scalp and hair follicles, providing a conducive environment for healthy hair growth.
It has a rich history, dating back thousands of years, and it has been utilised for various medicinal purposes. Fun fact; it was mentioned in ancient Egyptian medical texts as a cure for eye irritation. However, its potential benefits for hair growth have gained significant traction in recent times, leading to its rise in popularity and recognition within the beauty community.

‘We have to be very specific when addressing hair growth. Castor oil has the amazing hair health benefit of helping to lock in moisture and is extremely nourishing and therefore will help the condition of the hair, preventing moisture loss helping to keep hair hydrated – great for dry hair, and preventing breakage, ‘ reveals Anabel Kingsley, Brand President and Consultant Trichologist at Philip Kingsley. ‘However it will not stimulate hair growth from the root,’ she adds.

Is castor oil good for thinning hair?
While castor oil is often touted as a remedy for thinning hair, there is no conclusive scientific evidence to support this claim. ‘Its moisturising properties may benefit the hair, but its effectiveness for hair regrowth is uncertain,’ explains Paul Windle, Founder of Windle London salon and Windle Lab haircare range.
‘There is a huge differentiation between thinning hair and thin hair. Thinning hair or hair thinning refers to female or male pattern hair loss, also known as androgenetic alopecia. This type of hair loss is genetically predetermined and the only FDA medically approved solution is Minoxidil, ‘explains Kingsley.
Philip Kingsley provide Minoxidil topical scalp drops at their Trichological Clinics to provide follicle protection FYI.
‘Thin hair however or hair feeling thin, can happen for a number of reasons such as breakage and even nutritional deficiencies. Castor oil would be of benefit if maintaining the healthy condition of hair, and thus in the case of breakage,’ she adds.
Is castor oil good for afro hair types?
Castor oil is a very rich oil, which can be beneficial for afro hair types as it provides high levels of moisture and helps combat dryness, which is a common concern for this hair type. Castor oil also helps with managing frizz and enhancing shine,’ says Windle.
‘It’s an ingredient that is well loved and used widely by those with afro-textured hair, where the coil is quite tight in appearance. There are many products on the market which contains this ingredient, including one of my favourites which I’ve been using recently by Cantu called Protective Styles Daily Oil Drops. You literally point the nozzle and apply directly to the scalp. Over time it works to aid growth and soothes the scalp,’ adds Hair Stylist Adjoa Obeng.
What is the best way to use castor oil on hair?
Castor oil can be applied directly to the scalp or hair. It is typically massaged into the scalp and hair, left for a few hours or overnight, and then washed out. Alternatively, castor oil can be mixed into a hair mask or conditioner for an extra boost of moisture, reveals Windle.
If using on afro hair types, Obeng recommends that you ‘apply to a clean scalp and limit to maximum three times a week in between shampooing and conditioning the hair. You can also mix with your conditioner and create a DIY hot oil treatment, by covering your hair with a towel or cap to seal in heat for 30 minutes.’
Is castor oil good for the scalp?
If you have a very oily scalp then Kingsley advises to steer clear. ‘This can exacerbate oily scalp conditions such as dandruff and seborrheic dermatitis which can lead to hair loss. If your scalp is irritated or flaky look for an anti-microbial shampoo to gently exfoliate and soothe inflammation.’
However, Windle adds that is can be useful if have for ‘reducing dryness on the scalp.’ This is because castor oil is renowned for its high concentration of ricinoleic acid, a monounsaturated fatty acid known for its anti-inflammatory properties.
Ricinoleic acid is thought to promote blood circulation, which plays a vital role in stimulating hair growth.

Cold pressed castor oil is always best to use because it ensures that none of the precious nutrients are lost during the manufacturing process.

It’s really easy. Mensah says ‘apply castor oil to your scalp and roots using your fingertips. and leave it on for 2-3 hours before shampooing.’
