Helps prevent lice infestations and reduce the risk of reinfestation, keeping hair clean, soft, and easy to comb. Déparaz Preventive Shampoo is a hair care product developed to help protect hair against lice, especially during periods of increased risk of contagion, such as returning to school, attending daycare, or close contact with other children. Its formula incorporates Crystalysine technology, of plant origin, which forms a physical barrier on the hair fiber, making it difficult for lice and nits to attach. This technology provides protection against reinfestation for up to two months, according to the product information. In addition to its preventive action, the shampoo gently cleanses the hair and scalp and can replace your usual shampoo during periods of use. The formula is non-greasy, contains no silicones or sulfates, and was developed to facilitate washing without leaving hair heavy or sticky. It is suitable for all hair types, including curly, frizzy, and difficult-to-detangle hair. It can be used by adults and children from 1 year of age, including during pregnancy and breastfeeding, respecting the instructions on the packaging. The 150 ml packaging offers a practical solution to integrate into the hair hygiene routine during periods of greater exposure to the risk of infestation.
