PurposeDS Laboratories Spectral.RS Topical Treatment for Thinning Hair is a minoxidil-free hair stimulating formula to treat hair-loss and encourage regrowth. Lacking all unwanted side-effects of minoxidil treatments, Spectral.RS has been clinically proven to provide the appearance of thicker hair. MethodApply 10 sprays of DS Laboratories Spectral.RS twice per day directly to the area of hair loss or thinning. Rub in liquid evenly over the entire affected area then wash hands with soap and water immediately after use. Do not rinse. It is imperative that once begun Spectral.RS be used regularly without interruption in order to not lose progress during initial stages of use. Why it worksDS Laboratories Spectral.RS is one of the World’s first formulations to use Aminexil, which combats perifollicular fibrosis – a condition where the collagen in hair becomes rigid, pushing up roots and causing premature shedding. Spectral.RS also uses advanced Nanosome technology to deliver the integral substances to, and absorb them into, your scalp.
