Below are some of the active Ingredients for the LASH, BROW & HAIR formulas, and their roles in the hair growth cycle: Elastin — Active ingredient Targets both the anagen and late telogen stages of hair growth. It delivers elastin to the skin's matrix, which nourishes the cells responsible for producing hair follicles. Supports the body's ability to anchor the hair follicle "bulb" to the elastin root system, protecting the hair from premature shedding. Keratin – Active ingredient Addresses the telogen stage of hair growth and uses a unique DNA protein that is found in human hair. It visibly restores the density, shape and thickness of eyelashes and eyebrows. It's important to note that the quality of keratin can vary based on its source, with some being plant-based and others coming from animal by-products such as bovine blood plasma. We are always committed to being cruelty-free, and our unique proteins are one of the biggest breakthroughs you’ll find in our formula compared to other brands. Hepatocyte Growth Factor (HGF) — Active ingredient Effectively targets both the anagen and catagen stages of hair growth, providing significant benefits. It shortens the catagen phase while effectively extending the productive anagen phase of the natural hair follicle lifecycle. Furthermore, it works in close collaboration with the naturally occurring proteins that maintain the active phase of lash and eyebrow hair growth development, ensuring optimal results. Myristoyl Pentapeptide-17 — Active ingredient Addresses the anagen stage of hair growth, thanks to the powerful Liao-Oligopeptide, a bioavailable keratin-stimulating peptide that effectively signals the cells to significantly stimulate keratin genes. It thoroughly nourishes, stimulates, hydrates, and protects the hair follicle, providing unbeatable results. (+)-Cloprostenol Isopropyl Ester – Active ingredient Addresses the anagen stage of hair growth. Energizes the follicles and primes them to increase their rate of production, demonstrably invigorating the growth cycle.. Provides superior protection against breakage and thinning.
