DS Laboratories Spectral. DNC-S Breakthrough Hair Support System is so advanced that it comes as two separate formulas until users combine them during application for maximum performance. The minoxidil-free product delivers hair-recovery effectiveness for both men & women. DS Laboratories Spectral. DNC-S Breakthrough Hair Support System is today's most complex innovation to optimize hair & prevent its thinning because it expresses years of research, contains novel ion-channel openers, & transports key compounds for maximum stability. Prior to this minoxidil-free formula, many of the most promising combinations of ingredients had proven unstable. But in Spectral.DNC-S, more of these materials can be combined successfully. It is laden with beneficial agents, & a dual-chamber delivery system expands the capacity of one product to contain them all. In the complex biology of scalp, novel combinations of ion-channel-opening compounds, similar to minoxidil but from natural sources, can mimic pharmaceuticals but without the side effects. In this product, they can be deployed through a unique cosmetic treatment, not a drug. This new modality shifts the paradigm of hair-follicle care, becoming a new standard to target a wider spectrum of symptoms. The passionate pursuit of more advanced biotechnologies guides all development at DS Laboratories, whose objectives are wide-spectrum activity, long-term efficacy, comfortable wear, & enhanced overall health. Spectral.DNC-S means high performance in a healthy environment, unlike minoxidil-based products, which can irritate scalp & leave a greasy, sticky residue.
