What does pumpkin seed oil contain?

Pumpkin seed oil contains fatty acids, mainly linoleic and oleic acid, plus phytosterols and tocopherols from the vitamin E family. The amounts vary with the pumpkin variety, growing conditions and how the oil is extracted.

So oils sold under the same name are not identical, and cold-pressed culinary oil is not interchangeable with the standardised capsules used in studies.

How is it linked to DHT and hair follicles?

One mechanism studied in genetic hair loss is the conversion of testosterone to dihydrotestosterone (DHT) by the enzyme 5-alpha reductase.

The possible effect of pumpkin seed oil on this enzyme rests mostly on experimental research. How much it lowers DHT in the human scalp is not established, so “natural DHT blocker” should not be read as a proven treatment effect.

What does research on oral use show?

A double-blind, placebo-controlled study published in 2014 included 76 men with mild to moderate male-pattern hair loss, who took a capsule preparation containing 400 mg of pumpkin seed oil a day for 24 weeks.

Mean hair count in the measured area rose by about 40% from baseline in the active group and 10% in the placebo group. This does not mean 40% denser hair across the whole scalp or the same result for everyone, and hair thickness did not differ between groups.

The small sample, the use of one specific capsule and funding by the company that supplied it limit how far the results apply to other products.

Can applying it to the scalp help?

A 2021 study of 60 women with female-pattern hair loss compared pumpkin seed oil applied to the scalp with 5% minoxidil foam over three months. The pumpkin seed oil group showed some dermoscopic improvements, such as fewer fine (vellus) hairs and more signs of regrowth.

Both groups improved within themselves, but the study does not show pumpkin seed oil to be better than minoxidil, which has stronger evidence in female-pattern hair loss.

Can capsules, pure oil and shampoo be judged the same way?

Results for an oral preparation cannot be applied to oil rubbed on the scalp, and results for leave-on scalp products do not apply to quickly rinsed shampoos.

Concentration, formula, route and duration matter. Containing pumpkin seed oil does not make a product clinically proven against hair loss. In Türkiye, capsules are usually sold as food supplements and oil-based serums and shampoos as cosmetics; neither is a medicine.

What to look for when choosing pumpkin seed oil products in Türkiye

In Türkiye, pumpkin seed oil comes in three forms: cold-pressed culinary oil, capsules sold as food supplements, and cosmetic serums, tonics and shampoos for the scalp. None of these is a medicine, and none may be marketed as a treatment for disease.

• For capsules and tablets, look for the Ministry of Agriculture and Forestry food-supplement approval or permit details on the pack.
• Cosmetics should list the manufacturer and the company responsible in Türkiye.
• Check that the label clearly states the amount of pumpkin seed oil and other active ingredients; only then can it be compared with products used in studies.
• Patch-test pure oil on a small area before applying it to the scalp, and avoid it if you have redness, itching or eczema.
• Be cautious with products that promise to “definitely stop” hair loss.

Hair loss can be caused by anaemia, thyroid disease, hormonal disorders, stress or medication side effects. For patients in Ataşehir and Istanbul, the right approach is to find the cause first and then, if needed, plan options such as hair PRP, hair mesotherapy or medication alongside plant-based products.

How long before results can be expected?

Studies assessed results over three to six months. This is not a promise; without knowing the cause of hair loss and the product, no one can say hair will grow within a set time.

Pumpkin seed oil has promising findings for hair health. If you are considering it, the cause of hair loss should be found first and product choice and follow-up tailored to you. Sudden, patchy or rapidly progressing hair loss should not be managed with plant products alone. For patients in Ataşehir and Istanbul, the first step is a medical assessment.
