Does castor oil help hair growth? That's the first thing we need to think about before going with the popular advice of "Just put castor oil on their hair. It’ll make it grow.”
This has been one of those haircare tips that gets passed from one parent to another, especially when you’re trying to help your child grow and maintain their curls.
But does castor oil actually help hair growth?
The honest answer is a little more than what social media makes it sound.
First, let's understand what the oil is, what it does, and how it improves hair quality.
Castor oil comes from the seeds of the Ricinus communis plant. It is particularly rich in ricinoleic acid, which makes up roughly 89–92% of its fatty acids.
In cosmetics, castor oil is primarily used as a conditioning ingredient, among other formulation functions. A recent Cosmetic Ingredient Review safety assessment showed that castor seed oil and related ricinoleate ingredients are safe, but that doesn't mean it has been proven to stimulate hair growth.
One of the most useful things to understand is that an ingredient can help care for hair without directly making it grow faster. Castor oil is also often associated with longer, thicker-looking hair.
Now the question is, what exactly does the oil do?
So what can castor oil actually do for hair?
This is the point where you have to think less about making new hair grow and more about caring for the hair you already have.
Castor oil is used in haircare formulations for its conditioning properties, and there is evidence that it improves the appearance of hair, including luster.
For curly and coily hair, that can be useful because everyday hair care involves a lot of handling.
And the truth is, the better you care for the existing hair, the easier it is to maintain the length your child is already growing.
Hair growth vs length retention: the part parents often miss
One thing that parents often miss is the understanding that your child's hair can be growing from the scalp while you struggle to see any extra length.
So the most important question you must ask is,“How can I help my child's existing hair stay soft, conditioned, and easier to handle?”
That shift can make your hair routine much more practical.
Here are a few simple things that can help your child's hair
- All detangling should be done from the ends upwards, rather than dragging a brush from root to tip.
- Don't wait until the hair is extremely dry before adding your moisturising product.
- Give products a little time to settle into the hair before styling.
-
Keep hairstyles comfortable, particularly around the hairline.
- Pay attention to how the hair feels, rather than adding more product simply because you're chasing length.
Benefits of castor oil on your hair?
Here are some of the reasons it has earned its place in haircare.
1. It helps condition the hair
Castor oil is an emollient oil, meaning it can help make the hair feel softer and smoother. This matters particularly for textured hair, which can sometimes feel dry or rough between wash days.
2. It helps hair feel less dry
One of the reasons oils are commonly used in haircare is their ability to sit on the hair and help reduce moisture loss from the surface.
Castor oil is particularly rich and viscous, so it can give hair that soft, conditioned feeling many parents are looking for after moisturising.
That doesn’t mean pouring more oil onto the hair is always better. The goal is comfortable, conditioned hair - not hair weighed down with product.
3. It can add softness and shine
Well-conditioned hair tends to look smoother and more lustrous, and castor oil can contribute to that finish.
4. It can make textured hair easier to manage
For curly and coily hair, haircare isn't only about how quickly the hair grows from the scalp, it’s also about what happens to that hair after it grows.
A child’s hair may be growing perfectly well, but frequent tugging during detangling, rough handling, tight styles, and unnecessary manipulation can make it difficult to retain length.
Keeping the hair conditioned and manageable can help you handle it more gently.
5. It can support length retention
Castor oil isn't proven to make hair grow faster. But caring properly for the hair can help you avoid some of the everyday things that contribute to breakage.
Why FORHALLE uses castor oil in Her Product
At FORHALLE, we've never believed an ingredient needs to be famous before it earns a place in a formula.
Our haircare tradition goes back five generations to 1905, and that has always shaped how we think about ingredients: what does it actually bring to the hair, and how does it work alongside everything else?
That's why castor oil is part of the ingredients for our Seriously so soft Blueberry Curl Butter.
We use it as part of a considered formula designed to help make curls feel softer, conditioned, and easier to manage.
And castor oil isn't working alone.
It's one part of a formulation alongside ingredients such as blueberry, shea, cocoa, sweet almond, and jojoba oils.
That's important because good haircare isn't usually about finding one magical ingredient.
It's about how the ingredients work together.
How to use castor oil for your child's hair
You don't necessarily need to buy a bottle of pure castor oil and apply it directly to your child's hair.
A formulated hair butter that already contains castor oil can be a much simpler way to include it in your routine.
For example, with Blueberry Curl Butter, start with damp hair and work section by section.
Then give the product 2–3 minutes to settle into the hair before styling.
That small pause can make a difference to how the product feels and gives you time to work through the hair without immediately piling on more.
The aim isn't to drench the hair in oil.
It's to give the hair the conditioning care it needs before you move on to detangling and styling.
Here are Some FAQs By Parents
Does castor oil make children's hair grow faster?
There isn't strong evidence that castor oil makes hair grow faster. It is better understood as a conditioning ingredient used in cosmetic haircare formulations.
Is castor oil good for children's curly hair?
Castor oil can be included in haircare formulations designed to condition and care for curly hair. The finished formulation and how it suits the child's individual hair are more important than relying on castor oil alone.
Can castor oil help with hair breakage?
Castor oil isn't a proven treatment for hair breakage. However, using a well-formulated conditioning product can make haircare and detangling more manageable, which is part of a gentler routine.
How often should I use castor oil on my child's hair?
There isn't one universal schedule for castor oil. If you're using a formulated product containing castor oil, follow the product's intended use and adjust based on how your child's hair responds.
A better way to think about castor oil
The most important thing here is understanding what the ingredient can realistically contribute - and choosing a formula that supports the way you actually care for your child's curls.
