What Else You Need to Know: The Light-Activated Scalp Serum is a leave-in, no-rinse formula combining time-honored botanicals with advanced bioactives to optimize your scalp environment and encourage fuller-, stronger-looking hair over time. It's also uniquely formulated to complement the HigherDOSE Red Light Hat (sold separately), so every session you're already doing works that much harder. Powered by copper peptide GHK-Cu—a clinically studied peptide—it supports follicle health and helps improve the appearance of hair density. It's backed by two patented plant stem cell extracts, apple and bamboo, that work to protect from the stressors behind thinning and weakening over time. The rosemary hydrosol base delivers antioxidant and circulation-supporting benefits before the actives even kick in. Green tea leaf extract adds another layer of protection against oxidative stress while hyaluronic acid brings intense scalp hydration and panax ginseng root energizes follicles. It absorbs quickly, leaves zero residue, and fits seamlessly into the routine you already have. Pair it with the included Scalp Derma Stamp to encourage higher absorption, boost scalp circulation, and support the natural skin-renewal process.
