Healthy hair starts with a healthy scalp. The Hair Serum from Caldera + Lab helps support scalp health. Its ExoDense Complex combines biotechnology and plant bioscience to deliver one billion plant-based exosomes per dropper, along with adaptogenic (antioxidant) botanicals, caffeine, and essential minerals to fortify the scalp microbiome, support the hair growth cycle, and enhance hair strength. Biomimetic amino acids, peptides, and plant proteins mimic hair's natural building blocks, and phytonutrient extracts derived from Swiss botanicals help fortify follicles. Just 2-3 pipettes at night are enough to keep hair stronger, fuller-looking, and healthier.
