Rahua Classic Shampoo
At a glance
Summary
Rahua Classic Shampoo scores 88/100 -- one of the cleanest commercial shampoo formulas on the market, with a near-flawless exclusion list. Zero silicones, zero PEGs, zero parabens, zero phenoxyethanol, zero MCI/MIT, zero EDTA, zero synthetic fragrance (Palo Santo Wood Oil provides the natural aroma), zero dyes, zero acrylates/microplastics, zero formaldehyde-releasers, zero ethanolamines (DEA/MEA/TEA), zero SLS/SLES. The plant payload is exceptional: Ungurahua (Rahua) Fruit Oil -- the proprietary Amazonian palm fruit oil sustainably harvested via Rahua's Symbiotic partnerships with Quechua-Shuar communities -- plus six organic-certified plant extracts (sugar cane gentle AHA, palo santo, aloe, green tea, rosemary, raspberry leaf). Hydrolyzed Quinoa delivers complete-protein conditioning (all 9 essential amino acids, unique among hair proteins). Glycerin + Panthenol round out the humectant-vitamin layer. Capryloyl Glycine + Caprylic Acid are coconut-derived preservation boosters; Potassium Sorbate is the only traditional preservative -- a food-grade clean choice. Citric Acid replaces EDTA as the pH adjuster/chelator. The one demerit holding it back from the BASED/Boe Natural 94+ tier is Sodium C14-16 Olefin Sulfonate as primary surfactant -- milder than SLS/SLES but harsher than glucosides (EWG 2-3, can be drying). Rahua Beauty is independent (founded 2008).
