Did you mean Oligomeric Proanthocyanidins?

Glossary Oligomeric Proanthocyanidins

Oligomeric proanthocyanidins (OPCs) are a class of flavonoids found in various plants, particularly in grape seeds, pine bark, and certain fruits. They are known for their antioxidant properties, which can help protect hair follicles from oxidative stress, a factor that contributes to hair loss. OPCs may also promote blood circulation and improve nutrient delivery to hair follicles, potentially supporting hair growth. Their relevance in hair biology lies in their ability to combat inflammation and promote overall scalp health, making them a subject of interest in hair loss treatments.
