Key Benefits

Voluminous Shampoo adds natural lift and body while cleansing the hair and scalp. The formula features rahua oil, an omega-9-rich extract from the Amazon that penetrates deeply to fortify strands, lock in colour, and support scalp health. It contains lemongrass to balance oil production and add bounce, helping extend time between washes.

With added green tea antioxidants, the formula protects against damage while clarifying without stripping natural oils. It includes shea butter to soften, hydrate, and seal in moisture, while eucalyptus offers purifying benefits and lavender provides a calming, uplifting aroma.

This award-winning formula creates a balanced lather that removes build-up and delivers fullness without dryness. Designed for fine to medium hair, Voluminous Shampoo leaves hair clean, bouncy, and healthy, with lasting volume and vitality.

Rahua creates every formula with its Symbiotic® Standard, sourcing ingredients directly from the Amazon rainforest in a way that protects both the land and its people. Each ingredient grows in an untouched virgin forest, harvested with indigenous knowledge, and purchased at a fair price that sustains local traditions, builds economies, and empowers native communities. This approach ensures every product delivers plant-powered, vegan, and cruelty-free performance at salon level, while remaining colour-safe. Free from phthalates, sulphates, parabens, silicones, mineral oil, microplastics, petroleum, and artificial colourants, Rahua offers clean, ethical haircare that respects people, animals, and the planet.

Rahua was founded in 2008 by Ecuadorian-born hairstylist Fabian Lliguin and trend forecaster Anna Ayers, inspired by the extraordinary strength and shine of Amazonian women’s hair. The secret lay in rahua oil, a nutrient-rich extract packed with omega-9s and active botanical compounds. Determined to share this natural wonder while protecting the rainforest, Fabian and Anna built a brand rooted in clean, plant-based formulations and sustainable practices that empower indigenous communities. Through Rahua, you experience the power of the Amazon’s most potent ingredients while supporting the preservation of its people and environment—helping you nourish your hair naturally and responsibly.
