GSE STOPped is a product line based on Grapefruit Seed Extract and natural, functional components, devised for the prevention and elimination of head lice. GSE STOPped Shamppo and GSE STOPped lotion helps in preventing infestation because by enabling the formation of a protective film on the hair, nits have greater difficulty in anchoring on it: this way, lice cannot reproduce and stop infesting the scalp. In case of infestation, GSE STOPped Gel and GSE STOPped Foam act against lice and nits by suffocating them. Together with the barrier effect that makes it difficult for nits to cling onto the hair, infestation can be eradicated in a definitive, yet harmless way. GSE STOPped Comb, instead, is recommended for the mechanical removal of nits.
