Salmon sperm and especially its precious polydeoxyribonucleotide (PDRN) content have been the beauty industry's latest rising star ingredient. While generally embraced for regeneration, anti-inflammation and other skin repair benefits, PDRN has more recently followed the "skinification of hair" charge — into several KeraFactor brand products.
Nutrient Boost, Inflammation Reduction and Growth Activation
According to KeraFactor, PDRN holds the ability to repair tissue, reduce inflammation and activate growth signals. The ingredient was therefore incorporated into brow and lash serums, as well as KeraFactorMD brand scalp treatments to provide optimal conditions for regrowth, especially after procedures like microneedling or platelet-rich plasma (PRP) therapy.
Touted benefits, per the company, include:
- Enhanced blood flow: PDRN nourishes hair follicles by stimulating vascular activity.
- Inflammation reduction: It alleviates scalp inflammation, a common contributor to thinning hair.
- Growth activation: Dormant follicles are reactivated, promoting natural hair regrowth.
Peptides to Amplify PDRN
KeraFactor also adds biomimetic and copper peptides to the PDRN for a comprehensive hair restoration solution. The company reports:
- Biomimetic peptides: Mimic natural signals to stimulate follicle activity, and
- Copper peptides: Strengthen strands and improve scalp health, acting like a "fertilizer" for growth.
Science-based Revolution
According to KeraFactor, PDRN is a groundbreaking development in hair restoration and, when paired with peptides, it delivers a multi-targeted approach that "goes beyond hype and into true innovation."
