20 Apr 2020 --- Gelita’s Verisol bioactive collagen peptides have been found to improve hair structure by significantly increasing thickness and the proliferation of human hair follicle cells. This is according to a new randomized, placebo-controlled study by the Kiel Collagen Research Institute in Germany, which included 44 healthy women aged between 39 and 75, receiving a daily dose of 2.5 g of Verisol for 16 weeks. The discovery may point to the peptides’ potential for hair health and related NPD, beyond their already established benefits for skin and anti-aging.
