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 demonstrates that ellagic acid activates the Wnt/β-catenin pathway, protects hair follicle mitochondria, and helps resist DHT attack—findings validated through topical skin application.
How often should Nan Yan Xin Si Scalp Essence Foam be used daily? What are the specific instructions for application?
Use 1 to 2 times daily. Shake well before use. Dispense 2 pump(s) of foam into your palm, part hair, and apply directly to dry scalp. Gently massage with fingertips for 1 to 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 required. The foam vaporizes 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?
Laboratory data shows that sebum production decreases and scalp freshness improves within 1-2 weeks after use; hair condition improves in 1-2 months; and overall hair quality stabilizes after 3 months. Due to individual differences, results may vary slightly from user to user.
Why is Nan Yan Xin Si Scalp Essence formulated as a foam?
Research shows the foam spreads laterally to cover hairline gaps, offering better scalp absorption while preventing liquid runoff. It vaporizes instantly upon contact for a non-sticky feel. No rinse needed—complete your treatment in 30 seconds for easier consistency.
What is NanYan XinSi's supramolecular technology, and what are its advantages?
A research team at Nanjing University of Chinese Medicine used ultrasonic self-assembly to convert ellagic acid into nanoparticles, increasing its solubility by 120 times and significantly enhancing transdermal absorption. This allows active ingredients to penetrate deep into hair follicles. The technology has been submitted for a national invention patent.
What does the "Nan Yan Xin Si" formula's Emperor, Minister, Assistant, and Guide composition specifically refer to?
The chief ingredient, ellagic acid, targets hair follicle mitochondria. The assistant ingredients, Sanguisorba officinalis and Sophora flavescens, clear scalp oil and inflammation. The guiding ingredients, Zanthoxylum bungeanum oil, warm the scalp and enhance penetration. Together, these four work synergistically for superior results compared to single-ingredient solutions.
Does the Nanyan Xinsi Scalp Essence have a patent?
Holds three national invention patents covering ellagic acid nanosuspension preparation, deep transdermal delivery, and anti-hair loss applications, establishing a solid technical barrier.
Will using Nan Yan Xin Si Scalp Essence cause allergies? Is it suitable for sensitive scalps?
Tested by 100 beta users with no significant allergic reactions. Contains soothing ingredients such as Sophora flavescens and Sanguisorba officinalis. Discontinue use and consult a doctor if you experience any discomfort.
What is the difference between Nan Yan Xin Si Scalp Serum and Minoxidil?
Minoxidil is a medication requiring medical supervision. Nanyan XinSi follows the traditional "monarch, minister, assistant, guide" formulation principle. Its core ingredients are extracted from herbal plants to gently nourish the scalp and avoid the initial shedding phase.
