Castor oil: for skin, hair and more!

Updated on 2026-04-22

Summary: Castor oil: for skin, hair and more!

The chronicle looks at hair loss as a phenomenon that is increasingly present, amplified by social networks, but which has very real and varied causes. Beyond genetics and ageing, it can be influenced by hormones (particularly in women with postpartum or stopping the pill, and in men with DHT), stress, lack of sleep and certain nutritional deficiencies such as iron, zinc or vitamins B and D.

The importance of a good diet and a balanced lifestyle is therefore emphasized to support hair health. Last but not least, castor oil is presented as an effective natural solution for stimulating scalp circulation, strengthening hair and promoting greater density, provided the follicles are still active.

A phenomenon amplified by social networks

Hair loss has become an omnipresent topic, especially on social networks where miracle solutions and revolutionary products are circulating. But more than just a trend, it's an issue deeply linked to self-image, for men and women alike.

Multiple causes (different for men and women)

Contrary to popular belief, hair loss doesn't just depend on genetics or age.

• For women It can be linked to hormones (postpartum, stopping the pill), stress or aggressive aesthetic practices (coloring, heat).
• For men It is often hormonal, notably linked to DHT (derived from testosterone), which progressively weakens the follicles.

The importance of the basics: nutrition and lifestyle

Several factors can accelerate the fall:

• stress and sleep deprivation
• deficiencies in iron, zinc, B vitamins and vitamin D

Simple gestures can help:

• eat enough protein
• sun exposure
• make up for deficiencies (as needed)

Castor oil: a proven classic

A well-known natural remedy, castor oil :

• stimulates scalp circulation
• nourishes follicles
• helps thicken and strengthen hair

How to use it in practice

• apply to scalp
• massage for 2-3 minutes
• leave on for 30 minutes to 2 hours
• then wash
• repeat 2 to 3 times a week

Tip: mix with coconut or jojoba oil for a lighter texture.

Frédéric Bisson - Host 104.7FM:

Today, with Lynn Goneau, we're diving into a subject that's very, very sensitive for everyone. I'm on the verge of buying a plane ticket to Turkey to get my hair glued back on. You'll see if you're on social media, hair loss is everywhere on Tiktok, on Instagram. It's a big topic. It's a real phenomenon. Lynn Goneau naturopath in La Boite à Grains. Hello Lynn.

Lynn Goneau - Naturopath of La Boite à Grains:

Hello Fred. Yes, we are talking about hair loss.

Frédéric Bisson - Host 104.7FM:

Yes, it's hard to miss. Especially on social media.

Lynn Goneau - Naturopath of La Boite à Grains:

Ah, it's incredible. For the past few months, it's been impossible to scroll down without coming across a video about hair loss. They talk about miracle tricks, revolutionary products. It never ends and then you know Fred, it's because it's about something deeply human.

Frédéric Bisson - Host 104.7FM:

Or yes, that's it.

Lynn Goneau - Naturopath of La Boite à Grains:

In the past, we used to associate hair loss with genetics or aging. But now we're forced to admit that it's much more than that.

Frédéric Bisson - Host 104.7FM:

Yeah. Or, and I think, I don't know, it's a biological difference, but image-wise, men, women, it's not the same. Our system doesn't work the same way or for hair. It's all the same.

Lynn Goneau - Naturopath of La Boite à Grains:

There is a slight difference in women. You can associate a drop in hormones with stress, postpartum syndrome after childbirth or when you've stopped taking the pill. Uh, it's very important to point out that there are also beauty trends like straightening and repeated coloring. It's even more acceptable to go au naturale.

Frédéric Bisson - Host 104.7FM:

Or that, a flat iron, it cooks the hair at a given moment, it's not very good there.

Lynn Goneau - Naturopath of La Boite à Grains:

In men, it's a completely different scenario: hair loss, in other words, the hairline changing, or the beard growing unevenly. But that starts younger and younger. It's a matter of genetics, but above all it's hormonal in the famous DHT. It's a hormone derived from testosterone. We talked about testosterone last week, but this is like saying DHT to the men in your hair. Thank you for your services. We don't need you anymore, it's just that, quietly, it's that, it doesn't grow anymore, then it doesn't work anymore.

Frédéric Bisson - Host 104.7FM:

Okay, the damned, I'll try to address it. So, for those who are losing their hair, let's start with maybe some natural solutions. 

Lynn Goneau - Naturopath of La Boite à Grains:

Yes, it's true that there are several factors that can accelerate weight loss, such as intense stress and lack of sleep. Then there are nutritional deficiencies. We're talking about a lack of iron, zinc, it could be the B complex of all the B vitamins, vitamin D. And when there's a lack, the hair becomes thin. And when there's a lack, hair becomes thinner, more fragile, and then falls out more easily. So it's important to include good animal or vegetable proteins at every meal. If you're stressed, maybe add a B complex and, uh, maybe check your zinc levels, eh? You can find it in oysters and pumpkin seeds. We talked about this last week, then, uh, don't forget to get some sun, your vitamin D.

Frédéric Bisson - Host 104.7FM:

Uh, castor oil.

Lynn Goneau - Naturopath of La Boite à Grains:

Well, Fred, this is really, really interesting. Castor oil is a classic. It's the natural solution for hair regrowth. Our grandmothers even used it. And today, science has really confirmed that it works. It stimulates scalp microcirculation. When circulation increases, the little follicles receive more and more nutrients, more oxygen, which promotes denser regrowth. It also deeply nourishes the follicles. It naturally thickens hair. Helps reduce breakage.

Frédéric Bisson - Host 104.7FM:

It's funny because I use castor oil on my plants, like my orange trees, to remove bugs.

Lynn Goneau - Naturopath of La Boite à Grains:

There are many, many, many functions. Well, it can be for hair, beard, eyebrows and eyelashes. And especially for ladies. It's a nice alternative to glue. Extensions. Uh, yeah. Well, yes, and it damages them. It's also important to know that coconut oil won't make hair grow back if the follicle is dead. Okay, yeah. That's it. It's important. So if your hair is weak and hungry, you're going to lose density. It can really make a big difference.

Frédéric Bisson - Host 104.7FM:

So here's how it's used here, because on plants, it's easy. I imagine it's the coconut. It must be pretty much the same.

Lynn Goneau - Naturopath of La Boite à Grains:

You apply it directly, as you say, to your scalp, massaging it in for two or three minutes. Leave it on for 30 minutes to two hours, then wash your head. You do this two or three times a week. When we're talking about eyebrows, well, you can apply it with a little cotton bud there. Then, you'll, you'll really have a more beautiful, full beard. Pis. If you like it, because it's thick, you can mix it with a little jojoba oil or the coconut oil you have at home. You can mix it with a little jojoba oil or coconut oil that you have at home. Then it'll make application a little easier.

Frédéric Bisson - Host 104.7FM:

Yes. Then there's a little smell, but I'm angry about it, it looks like ben. I've been rubbing castor oil on my orange leaves for 10 years. To have known that Lynn. I've wasted ten years of my life, but, uh, you have a product.

Lynn Goneau - Naturopath of La Boite à Grains:

Well, there's the Palma Christi company, which has organic castor oil. And it's really great. And so inexpensive. It's amazing. Yes, it really works for hair loss. I personally use it. And I can tell it works.
