Scalp Fertilizer uses ReJuviance transdermal technology to deliver lactate stimulant across the scalp directly to balding hair follicles that need it. Recent research at the University of California Los Angeles discovered that increasing lactate production genetically in research mice affected their hair follicle stem cells which favorably affected hair growth. Delivering calcium lactate directly to your follicle stem cells provides the "scalp fertilizer" needed. The calcium lactate also surrounds existing hair strands, thickening them until the next shampoo, providing major "bulk" to your existing hair. This product also contains the DHT-blocker Beta-Sitosterol, Vitamin D3, and Vitamin E, all of which are needed by your follicles for normal hair growth.
