Eyelashes and eyebrows grow in cycles lasting a few months. During the cycle, hairs go through 3 different stages of life. They begin in anagen, the growth phase, in which they grow to a specific length and then stop. The hair follicle then enters the catagen phase where it will shrink down to hold onto the hair. Finally it enters the telogen phase in which the hair rests until it is ready to fall out and let a new hair grow through. The hair-anchoring plant extracts used in Full Lash & Brow promote a longer growth phase and a shorter rest phase. This gives each hair the time to maximise its health, eventually leading to longer and thicker lashes and brows. Eyelash-enhancing peptides stimulate the keratin growing genes to enhance density and the thickness of the hairs. Meanwhile, a combination of glycerin and hyaluronic acid keep the hair and its follicle hydrated for the perfect growth condition.
