Frequently Asked Questions

What is the Nanyan Xinsi brand, and what is its background?

Nanyan New Silk is a scalp care brand incubated by the hair research group at Nanjing University of Chinese Medicine. Our core team consists of current professors and graduate students, including 15 professionals across pharmacy, traditional Chinese medicine, and other disciplines. With an academician of the Chinese Academy of Engineering serving as our Chief Advisor, our multidisciplinary collaboration provides a solid foundation for continuous product innovation and iteration.

What are the core ingredients of Nan Yan Xin Si?

Key ingredient: ellagic acid (a natural polyphenol extracted from plants like raspberries and pomegranates), supplemented with Sanguisorba officinalis, Sophora flavescens, and Sichuan pepper oil, formulated according to the traditional "monarch, minister, assistant, guide" principle.

What is the scientific evidence for ellagic acid in treating hair loss?

A 2024 study in the Journal of Ethnopharmacology found that ellagic acid activates the Wnt/β-catenin pathway, protects hair follicle mitochondria, and helps defend against DHT attacks—effects confirmed via topical skin administration.

How often should Nan Yan Xin Si Scalp Essence Foam be used daily? What are the specific instructions for application?

Use 1–2 times daily. Shake well before use. Dispense 2 pump(s) of foam into your palm, part your hair and apply directly to a dry scalp. Gently massage with fingertips for 1–2 minutes until absorbed. No rinsing required.

Do I need to rinse out the Nan Yan Xin Si Scalp Essence Foam after use? Will it feel sticky?

No rinse needed. The foam instantly evaporates upon contact with the scalp, leaving behind active ingredients for a fresh, non-sticky feel that won't interfere with styling. If you prefer to wash it out, let the serum sit for at least 30 minutes.

How long does it take to see results with Nan Yan Xin Si Scalp Essence?

Lab data shows: reduced scalp oiliness and increased freshness within 1-2 weeks; improved hair condition in 1-2 months; and stabilized overall hair quality after 3 months. Individual results may vary.
