About
Garnier Olia Ammonia-Free Hair Color is formulated to provide maximum color performance while being very mild, gentle and helping to maintain hair quality. The formula is based on an ammonia-substitute called monoethanolamine, which helps the color to penetrate the hair with minimal disruption to the shaft. The product is oil-based and it has a pleasant floral fragrance which blends sweet, woody and citrus notes. Available in 24 shades.
