Pumpkin Seed Oil and Grape Seed Extract: How Plant-Based Ingredients Strengthen Your Hair Growth from Within
Plant-Based Active Ingredients in Focus: How Nature Supports the Hair Cycle
When it comes to hair loss, the term DHT (dihydrotestosterone) inevitably comes up sooner or later. This hormone is one of the main triggers for genetically caused hair loss because it causes hair follicles to shrink and shortens the growth cycle. While medical DHT blockers are often the first choice, natural alternatives are increasingly coming into focus in 2026 research. Plant extracts can be a valuable, gentle addition to the daily care routine.
One of the most promising discoveries in recent years is the so-called proanthocyanidins, which are particularly abundant in grape seeds. Current clinical data show that these powerful antioxidants not only neutralize free radicals but also improve the microcirculation of the scalp. A well-blood-circulated scalp is essential for the hair roots to be optimally supplied with nutrients. Furthermore, studies suggest that proanthocyanidins stimulate collagen synthesis in the scalp, giving the hair more structure and hold [1].
Pumpkin Seed Oil: The Green Gold for Hair Roots
In addition to grape seed extract, pumpkin seed oil is also gaining popularity. The phytosterols contained in pumpkin seeds are considered natural, gentle inhibitors of the enzyme 5-alpha-reductase, which is responsible for converting testosterone into DHT. Although the effect of plant-based blockers cannot be equated with prescription medications, studies show that regular use—whether internally or as a scalp massage—can positively influence hair density [2].
Additionally, pumpkin seed oil provides important nutrients such as zinc, magnesium, and vitamin E. Zinc is indispensable for keratin formation and ensures strong hair, while vitamin E protects the scalp from oxidative stress. A holistic approach that considers both the inhibition of DHT and nutrient supply forms the foundation for healthy hair growth.

Holistic Care: From Inside and Outside
Insights from naturopathy have long been integrated into modern care concepts. To achieve the best results, a combination of internal nutrient supply and external stimulation is recommended. Dietary supplements specifically tailored to the needs of hair roots can provide the body with essential building blocks. At the same time, the scalp can be treated directly with special serums and shampoos.
The KÖ-HAIR Circulation Serum Spray stimulates scalp blood flow and promotes nutrient absorption directly at the hair root.
A healthy scalp microbiome and an intact skin barrier are just as important as reducing DHT. Mild, nourishing shampoos optimally prepare the scalp for subsequent active ingredients and gently remove residues without attacking the natural protective layer. Regular scalp massage during washing additionally promotes microcirculation.

Conclusion: Harnessing the Power of Nature
Research in 2026 confirms: Nature holds a strong arsenal of active ingredients to counteract hair loss and promote healthy hair growth. While grape seed extract supports blood circulation and cell health, pumpkin seed oil offers a gentle way to reduce the influence of DHT. A well-thought-out routine that relies on high-quality, clinically tested products like the KÖ-HAIR care series combines the best of science and nature for strong, full hair.
