Pumpkin Seed Oil For Hair Growth: Is It Effective?

If you’ve been researching hair growth options for men, you’re most likely familiar with the old standbys: minoxidil and finasteride

These treatments are tried-and-true and FDA-approved to treat male pattern baldness

But there are plenty of other folk remedies and over-the-counter options for treating hair loss, too. 

Some work better than others, and some don’t work at all. Case in point? Pumpkin seed oil as a hair loss treatment.

Yeah, it’s a thing — but is it legit?

When it comes to pumpkin seed oil for hair growth, what’re the facts and what’s the fiction? 

Does it really work, or is it all just hot hair? What does the science have to say? Well, let’s have a look.

Pumpkin Seed Oil: What Is It?

Pumpkin seed oil is pretty self-explanatory. It’s an oil that’s extracted from the roasted seeds of a pumpkin, and has many reported health benefits — many of which related to its high content of carotenoids, fatty acids and vitamins. 

But one of the more recently explored benefits of pumpkin seed oil is hair growth in balding men.

Is Pumpkin Seed Oil Effective for Hair Loss?

Androgenic alopecia (AGA), or male pattern baldness, is the most common cause of hair loss in men. AGA affects up to 70 percent of men — especially later in life. 

Dihydrotestosterone, or DHT, is an androgen that contributes to the development of male sex characteristics, and is a major player in male AGA.

Pumpkin seed oil has been linked to positive effects on hair growth, especially in men. 

One 2014 study found that men who took 400mg of pumpkin seed oil per day for 24 consecutive weeks had 40 percent more hair growth than men in the placebo group.

The study was one of the most comprehensive studies of pumpkin seed oil on hair loss to date — but pumpkin seed oil wasn’t the only ingredient tested. 

It was tested as only one ingredient in a multi-ingredient supplement. 

Other ingredients in the supplement included evening primrose powder, corn silk powder, octacosanol, mixed vegetable powder, red clover powder and tomato powder. 

This means that pumpkin seed oil may only play a small role, or that these other ingredients may amplify the effects of the pumpkin seed oil.

It should also be noted that the study also tested a fairly small sample size: less than 100 men were given the pumpkin seed oil supplement.

The Science of Pumpkin Seed Oil for Hair Loss

We’re the first to admit that the science behind using pumpkin seed oil for hair loss is a bit lacking. 

The mechanism of action is still unclear, but research suggests that pumpkin seed oil may inhibit 5α-reductase — which produces DHT from testosterone — thereby reducing hair loss and promoting hair growth.

According to several animal studies, it has also been reported that pumpkin seed oil inhibits testosterone-induced enlargement of the prostate. 

The studies also suggested that pumpkin seed oil may be beneficial for the management of prostate gland enlargement. 

This study also confirmed that the intake of pumpkin seed oil at 320mg/day over 12 months is clinically safe and effective as a complementary treatment for prostate gland enlargement.

What does this mean for hair loss? 

Well, as we mentioned before, male pattern baldness is caused by DHT levels in the body. And prostate enlargement is also caused by DHT. 

Because pumpkin seed oil has been an effective treatment for prostate gland enlargement, we can extrapolate these findings and postulate that pumpkin seed oil may also work to reduce male pattern hair loss in men.

Of course, we should note that this postulation is an obvious stretch.

Another study conducted in 2017 posited that the phytosterols in pumpkin seed oil promote hair growth. 

Phytosterols are similar to cholesterol but have tons of health benefits. It’s thought that phytosterols may block some of the enzymes and hormones in the scalp that cause hair loss. 

Other natural ingredients can also have a similar effect to pumpkin seed oil. 

A 2016 study demonstrated that saw palmetto works in the same way. 

Our Thick Fix Hair-Thickening Shampoo contains saw palmetto to help promote volume and moisture.

Who Should Use Pumpkin Seed Oil For Hair Loss?

The short answer is: any man who is struggling with male pattern hair loss can use pumpkin seed oil. 

Pumpkin seed oil may be a natural alternative for men who don’t want to go the traditional prescription medication route.

Prescription hair loss treatments have side effects that some men may dislike. For example, Finasteride can decrease libido and ejaculate volume or cause erectile dysfunction, and minoxidil can cause scaling and itching of the scalp. 

However, that’s also not to say that pumpkin seed oil should be considered a suitable replacement for hair loss treatment standards like finasteride and minoxidil — it isn’t. 

All we’re saying is that it probably won’t hurt your hairline.

How Should I Take Pumpkin Seed Oil?

From topical application to capsules and spoonfuls of oil, let’s explore some of the different ways you can take pumpkin seed oil for hair loss.

Topical Pumpkin Seed Oil

You can apply pumpkin seed oil directly to your scalp. In a study conducted on mice, topical application of pumpkin seed oil increased hair growth after three weeks of treatment. 

Pumpkin Seed Oil Supplements

Pumpkin seed oil is sold in oil gel capsules, too.

An important thing to note is that many supplements are not regulated by the FDA. That means the quality and dosage of supplements you get may vary from manufacturer to manufacturer. 

For your safety, make sure to always purchase your supplements from a reputable source.
