The collection includes hard shampoos made from olive oil, made using the cold process. Solid shampoo is an extremely economical form of shampoo, as it lasts longer than liquid shampoo. At the same time, we make sure that we do not burden the environment with waste. Our shampoos are therefore carefully packed in sustainable packaging. They only contain ingredients that are biodegradable and do not accumulate in aquatic organisms. The hard shampoos of the Nona Luisa® brand ensure that your hair will regain its natural shine, that your scalp will restore balance and therefore no longer get greasy, the tips will remain intact, and as a result, your hair will become stronger.
