Hair loss and thinning hair are common concerns affecting millions of people worldwide. While there are many treatments available, natural remedies have gained popularity due to their minimal side effects. One such remedy is pumpkin seed oil, a nutrient-rich oil that has shown promising results in promoting hair growth.
In this article, we will explore the benefits of pumpkin seed oil for hair, how it works, the best ways to use it, scientific research backing its efficacy, and expert opinions from dermatologists in Pakistan and the USA.
What is Pumpkin Seed Oil?

Pumpkin seed oil is extracted from the seeds of the Cucurbita pepo plant. It is rich in essential nutrients, including:
- Fatty Acids (Omega-3 & Omega-6): Nourish the scalp and strengthen hair follicles.
- Phytosterols: Help block the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT)—a hormone linked to hair loss.
- Vitamins A, E, and K: Provide antioxidant protection and improve scalp health.
- Zinc and Magnesium: Essential minerals for hair growth and follicle strength.
How Does Pumpkin Seed Oil Promote Hair Growth?
Pumpkin seed oil helps hair growth through several mechanisms:
- DHT Blocker: High levels of DHT cause hair follicle shrinkage, leading to hair loss. Pumpkin seed oil inhibits the enzyme responsible for DHT production, promoting hair retention.
- Anti-Inflammatory Properties: A healthy scalp is essential for hair growth. The oil reduces scalp inflammation, preventing hair follicle damage.
- Improves Blood Circulation: Massaging pumpkin seed oil onto the scalp stimulates blood flow, delivering essential nutrients to hair follicles.
- Moisturizes and Strengthens Hair: The fatty acids in pumpkin seed oil deeply hydrate hair strands, preventing breakage and split ends.
Scientific Evidence Supporting Pumpkin Seed Oil for Hair Growth
Research studies have highlighted the effectiveness of pumpkin seed oil for hair growth:
- 2014 Study (Randomized Controlled Trial): Conducted on men with androgenetic alopecia (male pattern baldness), the study found that participants who took 400 mg of pumpkin seed oil daily for 24 weeks experienced 40% hair regrowth, compared to a 10% increase in the placebo group.
- 2021 Comparative Study: Found that pumpkin seed oil was as effective as 5% minoxidil (Rogaine) in treating hair loss in women with female pattern hair loss (FPHL).
How to Use Pumpkin Seed Oil for Hair Growth
Pumpkin seed oil can be used in two primary ways: topically and orally.
1. Topical Application (Directly on the Scalp)
Steps:
- Take 1-2 tablespoons of cold-pressed pumpkin seed oil.
- Warm the oil slightly (optional) and apply it directly to the scalp.
- Massage in circular motions for 5-10 minutes to enhance absorption.
- Leave it on for at least 30 minutes or overnight for deeper nourishment.

How Often? 2-3 times per week for best results.

- Coconut oil (for deep conditioning)
