Iroiro Natural Premium Semi-Permanent Hair Color is the first natural vibrant hair color with natural ingredients. Our new, natural-ingredient-based formulation is free of peroxide, ammonia, PPD, alcohol, and toxic and harsh ingredients, thus helping to ensure damage-free extra conditioning results with brilliant color. Our colors contain natural certified organic coconut oil for extra conditioning, as well as natural preservatives and natural Yuzu-cranberry fragrance. We do not contain following harsh chemicals and synthetic ingredients commonly found in many semi-permanent hair colors today: Propylene Glycol (petro chemical used in anti-freeze & brake fluids), Methylisothiazolinone / Methylchloroisothiazolinone (synthetic preservatives named Allergen of the Year in 2013), PEGs (synthetic chemicals classified as a known human carcinogen), Methylparaben (synthetic preservative can act as potential hormone disruptors) and more.
