KLORANE's BIO nettle shampoo-mask powder presents a revolutionary 2-in-1 solution in a cleansing powder format designed for application on damp hair. Crafted specifically by Klorane's research team for those with oily hair and scalps, it offers a gentle yet effective cleansing experience, targeting impurities and excess oil from the roots. Featuring a "drying" action, it swiftly removes unwanted buildup and helps re-establish scalp balance, allowing for intervals between washes of up to 48 hours. This eco-friendly formula is made with plant-derived active ingredients, including purifying white nettle root and highly absorbent clay. As a result, hair feels soft and airy while maintaining cleanliness for an extended period. In addition to its performance, the product is environmentally responsible, utilizing 100% recyclable packaging and needing 80% less water compared to traditional shampoos. *Sebum levels were evaluated through biometric testing in a group of 31 participants 48 hours post-application. **As per OECD Standard 301B. ***An independent life cycle assessment was completed by DURACONSULT in 2020.
